Thanks for the past—looking ahead to new adventures
This is my final editorial as Editor-in-Chief of Maintworld Magazine.
As of January 2025, Jari Kostiainen has taken over the role, bringing fresh leadership to the publication. We’ve also restructured our editorial team, and I’m pleased to welcome back two familiar faces—Nina Garlo and Mia Heiskanen.
For me, this marks the conclusion of my full-time working life, though I won’t be stepping away from the maintenance scene entirely. I will continue contributing to Maintworld as a freelancer, and in my role as a Board Member of the European Federation of National Maintenance Societies (EFNMS), I remain well-positioned to follow the latest developments in maintenance and asset management. Over the years, my work in this field has evolved into a passion, enriched by a strong professional network and many valued friendships.
The Growing Importance of Asset Management
Asset management is becoming an increasingly critical focus for many companies. However, its full implications for maintenance professionals and production teams are still being defined.
Another key topic shaping the future of our industry is artificial intelligence (AI)—a subject we’ve covered extensively in our magazine. Whether AI will completely transform maintenance remains to be seen. Some have already raised concerns about unnecessary hype surrounding AI and its effects.
While AI and asset management are important, we must not overlook the fundamental skills essential to maintenance. After all, industries worldwide quite literally keep moving thanks to a thin layer of oil within machines, components, and moving parts. The expertise required to maintain these essential systems remains irreplaceable.
As I step into a new phase, I would like to take this opportunity to say thank you to all the colleagues, professionals, and friends I’ve had the privilege of working with over the years.
This issue will also feature an overview of Jari Kostiainen, who will be leading Maintworld into the future.
We continue to welcome your feedback and story ideas.

Painting the Picture of Cybersecurity
Cyber threats are no longer confined to computer screens as they shape industries, economies, and even societies. In this exclusive interview, cybersecurity global expert Mikko Hyppönen paints the picture how the digital battlefield has evolved, what industrial leaders must do to protect their business operations, and why AI-generated art unsettles him.
The walls around Mikko Hyppönen tell a story. Abstract paintings, digital sculptures, and eerie sound installations inspired by cyber threats surround him. Standing in the heart of Museum of Malware Art, the world’s first cybersecurity-themed art gallery at
WithSecurity headquarters Helsinki, he speaks about a different kind of artistry, the symphony of cyber defense, where every note can make the difference between harmony and chaos.
Hyppönen, a legendary cybersecurity expert and global thought leader, has spent decades tracking the evolution of digital threats. But for him, the battle against cybercrime is more than just a technical challenge; it’s a fundamental aspect of modern society’s survival.
The evolution of cyber threats. Looking back at his career, Hyppönen reflects on how dramatically the cybersecurity landscape has changed. “When I started in the 1990s, viruses were mostly created by hobbyists—teenagers writing code for fun, sometimes destructive, but without a real financial motive. Today, we are facing highly organized crime syndicates and nation-state actors who conduct sophisticated attacks for power, money, and political gain.”
One of the most surprising transformations has been the industrialization of cybercrime. “Hackers don’t just create malware anymore,” he explains. “They run full-fledged businesses, complete with customer support for victims who are paying ransoms. The attacks are automated, efficient, and relentless.”
The industrial cyber war is a new battlefield. “Technology revolutions shape our world more than anything else,” Hyppönen states. “We’ve seen it with the internet, mobile technology, and now artificial intelligence. Each revolution brings progress but also risks.”
For industrial and manufacturing companies, these risks are no longer hypothetical. Cyberattacks on factories and production lines are becoming as disruptive as physical disasters like fires or power failures. “The difference is that no arsonist stands outside a factory trying to set fires every single day. But cybercriminals are constantly trying to break in, every hour and every second.”
Recent attacks have shown how organized and persistent cybercriminals are. “These aren’t lone hackers in basements,” Hyppönen warns. “These are fully structured organizations and the methods they use range from exploiting outdated systems to deploying sophisticated AI-driven phishing campaigns.”
The weakest link is connectivity and complacency. Many industrial leaders still believe they are not targets. “Why would they come after us?” is a common sentiment, Hyppönen says. “But when you analyze attack patterns, you see no logic in victim selection. One day, a steel manufacturer in Canada. The next, a furniture company in the Netherlands. Hackers don’t choose their victims; they find vulnerabilities and exploit them.”
What is a common entry point for these attacks? Poorly secured remote access systems. In the race for efficiency and digital transformation, factories have connected their networks in ways that expose them to threats. “Every system today assumes that electricity and the internet will always be there,” Hyppönen explains. “The moment one fails, production halts. In ten years, losing internet connectivity will be as catastrophic as a total electricity failure today.”
Seeing the unseen. When asked how companies can defend themselves, Hyppönen emphasizes one thing: visibility. “You can’t protect what you can’t see. Do you know how many devices are connected to your company network? How many are running outdated software and how many have unnecessary access to critical systems?”
Hyppönen recommends industrial companies to conduct regular security audits, penetration tests, and continuous network monitoring. “Think of it like tuning an orchestra. If one instrument is out of tune, the entire performance suffers. The same applies to cybersecurity. A single vulnerable device can be an entry point for disaster.”
One of the most effective ways to test a company’s vulnerabilities, he adds, is to order a controlled attack. “Ethical hacking exercises allow organizations to identify weak points before real attackers do. We conduct these penetration tests, and, in my experience, there is no system that cannot be breached. Once vulnerabilities are found and fixed, the test should be repeated to ensure security improvements hold.”
The AI dilemma: art or algorithm? Despite his fascination with technology, Hyppönen is not entirely comfortable with all aspects of artificial intelligence. “I don’t particularly like the idea that AI can create art, whether it’s music, poetry, or visual art pieces,” he admits. “Creativity has always been uniquely human, and the thought of a machine generating something deeply emotional feels unsettling to me.”
To illustrate his point, Hyppönen recalls an example. “Last year, a song generated entirely by AI made it to the German single charts. The AI composed the melody, wrote the lyrics, arranged the music, and even synthesized the vocals. No human intervention. And yet, it became a commercial hit.”
He pauses for a moment before adding, “That’s both impressive and terrifying despite the fact that I actually liked the song.”
What’s Next? Looking ahead, Hyppönen sees an even more disruptive technological shift on the horizon: quantum computing.
“Once we have sufficiently powerful quantum computers, they will break most of today’s encryption standards,” he warns. “This means that every piece of encrypted data stored today might become readable in the future. Organizations need to start preparing for post-quantum cryptography now.”
The implications for industry are profound. Secure communications encrypted financial transactions, and intellectual property protection all depend on encryption. “If we don’t develop new security standards in time, we could face a global crisis where everything we thought was safe, is suddenly exposed,” he adds.
The man behind the mission. For someone who spends his days battling digital criminals, how does Hyppönen unwind? The answer lies in a different kind of machine: the pinball machine. “I love playing pinball,” he says with a smile. “I even compete at the national level.” Restoring and maintaining vintage pinball machines gives him the same satisfaction as fighting cyber threats. Both require precision, patience, and an eye for patterns.
But ultimately, what keeps Hyppönen motivated is the bigger picture. “Cybersecurity isn’t just about protecting computers. It’s about protecting societies,” he says. “In a world where everything runs on technology, securing digital infrastructure is as crucial as securing physical borders.”
Hyppönen also highlights the value of working with a team of top-tier professionals from around the world. “The best part of this job is working alongside some of the most brilliant minds. Together, we help organizations during their worst moments: when they’re in the middle of a crisis and need real solutions fast.”
As he walks through the gallery, past an AI-generated piece visualizing a ransomware attack, Hyppönen pauses. “We’re in a digital renaissance. And like any great era of change, it comes with both beauty and destruction. Our job is to make sure the balance tips toward the right side. The cyber symphony is now playing, but the question is: are we listening?”
According to Mikko Hyppönen, one of the most surprising transformations has been the industrialization of cybercrime
He works as the Chief Research Officer at WithSecure and as the Principal Research Advisor at F-Secure. With over 30 years of experience, he has been instrumental in battling major cyber threats and has worked on some of the most significant malware outbreaks in history. Hyppönen has also been a key figure in uncovering cybercrime operations and online espionage.
Hyppönen has been named one of the 50 most influential people on the web by PC World and was recognized as a “Code Warrior” by Vanity Fair. He has written extensively for publications such as Scientific American and Foreign Policy, further solidifying his position as a thought leader in the field.
In addition to his speaking engagements, Hyppönen is the author of the book If It’s Smart, It’s Vulnerable, where he discusses the security risks posed by modern technology.
From Invisible Threats to Visible Art
“While malware was never meant to be art, it reveals an unintended artistry — a creativity born from skilled programming mixed with disruptive intent. By bringing malware and art together, the Museum of Malware Art lets us look beyond the code to see the bigger picture these digital threats paint a story about trust, vulnerability, and the hidden effects of technology.”

Smart Welding Revolution
As industries worldwide grapple with the shortage of skilled welders, automation is stepping in to bridge the gap. Kemppi, a leading innovator in welding technology, is at the forefront of this transformation, working alongside research institutions and industry partners to develop solutions that improve efficiency, quality, and adaptability.
Kemppi’s latest collaborative project involves VTT Technical Research Centre of Finland, Tampere University, and several industrial partners, including Wärtsilä Finland Oyj. The initiative aims to enhance robotic welding and cobot welding to address challenges in automated welding, particularly in low-volume, high-variation production environments.
“One of the key issues in automated welding is ensuring consistent quality while adapting to variations in materials, joint geometries, and positioning errors, says Artturi Salmela, Product Manager for Automation at Kemppi.”
“Through advanced process control and real-time monitoring, we can dynamically optimize welding parameters, reducing errors and improving the overall welding quality.”
Wärtsilä Case: Tackling Large-Scale Welding Challenges
A prime example of this technology in action is Wärtsilä’s production of diesel power plant components. These large, complex structures require precision welding, and achieving high quality with traditional automation has been difficult due to variations in the workpieces. Wärtsilä faced significant challenges with ensuring the structural integrity of massive engine base frames, which require numerous high-quality welds in complex geometries.
The key obstacles:
• Inconsistent workpiece geometry: Large parts had minor but impactful variations, requiring flexible welding approaches.
• High material thickness: Thick metal structures demanded precise heat input and deep penetration welding techniques.
• Quality assurance: Maintaining uniform quality across vast surfaces while minimizing rework and production delays.
To address these, the project implemented real-time seam tracking and adaptive welding control, improving consistency and reducing manual intervention. Additionally, advanced welding cameras, such as those developed by Cavitar Oy, enabled defect detection and process monitoring, ensuring precise execution. These enhancements led to higher efficiency and significant reductions in welding errors.
“The project has already delivered promising results, particularly in seam tracking and AI-assisted welding quality monitoring, Salmela notes.”
“We’ve successfully reduced error rates and improved welding precision. Moving forward, we will continue refining the AI-based welding control and further integrate cobot solutions to enhance flexibility and efficiency in complex welding tasks. The goal is to develop a robust, scalable automation framework that can be implemented across different industrial applications.”
What is cobot welding?
Cobot welding refers to the use of collaborative robots (cobots) in welding applications. Unlike traditional industrial welding robots, which operate in isolated automated cells, cobots are designed to work alongside human welders. These robots assist in welding tasks by automating repetitive actions, enabling increased efficiency and precision while allowing human welders to focus on more intricate work. Cobots are typically lightweight, easy to program, and adaptable to various production needs, making them an ideal solution for manufacturers looking to enhance productivity without fully replacing skilled labor.
Enhancing human and machine collaboration
A breakthrough in welding automation has been the adoption of collaborative robots (cobots). Unlike traditional industrial robots, cobots work alongside human welders, handling repetitive tasks while allowing skilled workers to focus on complex, high-value welds.
Kemppi’s cobot welding solutions offer several key benefits:
• Improved productivity: Cobots assist welders by automating monotonous welding tasks, increasing overall output.
• Flexibility: Unlike fully automated welding cells, cobots can be easily reprogrammed for different tasks, making them ideal for dynamic manufacturing environments.
• Ease of use: Cobots are designed with intuitive interfaces, allowing welders with minimal automation experience to operate them effectively.
• Enhanced ergonomics: By reducing the need for welders to perform physically demanding and repetitive tasks, cobots improve workplace conditions and reduce strain-related injuries.
One successful implementation of cobot welding has been in manufacturing components for heavy industry, where parts are often large and require multiple welding passes. By using cobots, manufacturers have been able to achieve greater consistency while reducing fatigue-related errors among welders. In Wärtsilä case, cobots have played a crucial role in handling fewer complex welds while human welders focused on more critical joining tasks.
The future of welding automation
The long-term goal of this initiative is to create an ecosystem where automated and collaborative welding solutions coexist efficiently. As robotic welding technology continues to evolve, manufacturers will be able to scale production while maintaining high-quality standards.
“Cobots and robotic welding won’t replace skilled welders entirely, but they will significantly enhance their productivity. By combining human expertise with automation, we can achieve better efficiency, improved quality, and a more sustainable manufacturing process, Salmela concludes.”
Kemppi has already seen success with cobot welding solutions, which have proven to increase efficiency while maintaining high-quality standards. As industry embraces these advancements, the role of automation in welding will only grow, helping manufacturers meet increasing demands with greater flexibility and precision.
Key Facts:
• Project partners: Kemppi, VTT, Tampere University, Wärtsilä, Cavitar Oy, HT Laser, Visual Components
• Focus areas: Cobot welding, robotic welding, real-time quality monitoring, seam tracking
• Key technologies: Collaborative robots, advanced welding cameras, adaptive process control
• Industry impact: Increased efficiency, improved welding quality, reduced reliance on manual labor
• Outlook: Cobot-assisted welding increasing automation while supporting human expertise

Artificial Intelligence Needs an Expert Partner
Artificial intelligence (AI) is well-suited for various applications in maintenance, if development considers application-specific requirements and limitations. Reliable models and expertise don’t need to be reinvented through AI; instead, AI can be applied selectively. The importance of staff training is increasing.
Partial solutions developed using narrow AI for utilizing datasets create insights into the usefulness of AI in organizational business and technological environments. Flexible AI applications tailored to different targets provide increasing benefits through a better cost-benefit ratio. However, many elements typically required for solutions are not feasible to achieve solely with AI. In such cases, hybrid solutions, combining AI with components developed using other methods, are necessary.
Narrow AI brings tools for effective data utilization
The broader use of data requires the adoption of new methods, which demand technological readiness and trust in the quality and efficiency of these methods. While many building blocks for developing AI solutions already exist, their effective use requires training and engagement, enabling individuals to use AI as a tool to enhance their work rather than replace it.
The quality of the required data has slowed down the adoption of these methods and computing capabilities. Solutions within computational intelligence methods can also operate with less-than-perfect data. AI can also drive improvements in data quality and encourage more accurate record-keeping by giving data a clear purpose.
Progressing through hybrid solutions in maintenance
When AI is incorporated into decision-making, comprehensibility becomes a central requirement. Solutions brought by deep learning can often be too complex to replicate consistently. Despite their appeal, incorporating decision-making into deep learning easily becomes too unreliable. Instead of mere black-box solutions, hybrid approaches that use fuzzy logic can interpret AI operations. This is particularly effective in multi-objective optimization when operational conditions have a significant impact.
In maintenance, AI can leverage data collected from maintenance systems as well as as-close-to-real-time-as-possible information from condition monitoring. This is especially important at the device level. Expertise can be analyzed using generative AI, particularly in lifecycle management and during the procurement phase of production assets. Both paths converge at the operational level of production units. The need for training also varies depending on whether it’s condition monitoring, maintenance, or production asset management.
Condition monitoring:
Condition-based maintenance requires indicators based on signal processing and data analysis. AI can expand the range of indicators, but a more critical role is combining indicator data into new indicators and using their overall structure in diagnostics. There are similarities between similar machines and devices, but individual differences become apparent at least through operational history. General solutions may not achieve sufficient accuracy. Results can be improved by identifying similarities in machine-specific models, and recursive updates conducted periodically can further enhance equipment functionality.
Device-level operations:
The aim of AI at the device level is to produce increasingly refined maintenance thresholds. This can extend the intervals between scheduled and condition-based maintenance tasks, which in turn improves availability and/or reliability. The maintenance time saved can be used to improve the efficiency of the procedures themselves, reduce delays, and shorten active maintenance periods. Conversely, lengthening intervals between procedures may also enable the timely delivery of spare parts, which is crucial as delivery times increasingly lengthen.
Production unit/department-level operations:
In many technological environments, maintenance activities need to be packaged optimally, considering the criticality of individual devices and maintenance requirements. Such environments include continuous flow production structures with high availability demands.
AI can assist maintenance and production in optimizing downtime scheduling and selecting tasks to be included. An optimal timing may reduce breakdowns and other negative business impacts, potentially extending the interval between downtimes. AI algorithms can also be likely to enhance the efficiency of maintenance shutdowns. Realizing the benefits of optimal task packaging naturally depends on the business and technological environment in which maintenance operates. Initially, the use of AI requires substantial verification and validation, which increases the workload of experts at various levels.
Lifecycle management:
AI plays a role in producing data for examining requirements set by economic and business goals and strategies. This involves evaluating the economic and other business impacts of different operational alternatives, as well as optimal shutdown times and work plans.
Hybrid solutions are needed to address uncertainty when exploring the connection between shutdown scheduling and operational alternatives with cash flow calculations and the business and strategic impacts of actions. When comparing the optimal timing of replacement, improvement, and modification investments, hybrid solutions are required to manage technical, economic, and logistical uncertainties, focusing on the organization’s strategic goals.
Acquisition phase of physical/production assets:
The first definitions of production asset management, including maintenance, are currently made during the design phase. AI is expected to offer new tools to support both these definitions and the design of operational reliability. Digital twins and simulation tools based on them, as well as less demanding technical system models, aid in executing complex design tasks.
The requirements for AI are especially important during the design phase. At this stage, connections to business objectives, strategies, and accounting are particularly demanding due to greater uncertainty compared to the operational phase. These models are also useful tools during the plant commissioning and operational phases, with their quality improving as information accumulates with increasing operational hours.
Asset acquisition, as well as the procurement of individual devices, is expected to become more efficient, although continually growing requirements may work in the opposite direction. The technical documentation and work instructions provided by equipment suppliers are expected to improve, enhancing the quality and efficiency of AI use.
Organizational considerations:
AI development and implementation free personnel for development tasks, but applying AI requires understanding the methods involved. Training is needed to address uncertainty in planning and decision-making, as well as to grasp the principles, strengths, and challenges of multivariate methods.
Defining AI tools suitable for one’s application environment and ensuring high-quality, timely, and appropriately formatted data storage requires leveraging both documented and tacit knowledge of the entire technical staff.
Developing AI tools themselves requires not only expertise in various methods and influencing factors but also consideration of organizational-specific requirements and characteristics. For this reason, the demand for these services is expected to grow, but organizations themselves must understand maintenance requirements within the framework of asset management from a new perspective.
Organizational expertise remains central. AI does not replace this expertise but rather becomes a tool for analyzing situations, much like information technology did earlier. Over time, operations become more efficient, and quality improves. At the same time, expertise is enhanced. No fundamental leap or new mode is required. There will be impacts on work distribution and the use of external services, clarifying former practices.
The role of technology providers:
In terms of the technologies used by organizations, the role of technology providers (equipment manufacturers) or service providers with in-depth expertise in specific technological products will strengthen both in lifecycle management and maintenance. The role of the entire plant designer is also expected to strengthen, as AI use during the procurement phase is anticipated to increase. Conversely, organizations’ desire to avoid dependency on a single provider serves as a counterbalance.
Organizational impacts will also significantly depend on the specific organizational and technological environments; for instance, paper and steel mills require a different operating model than machine shops or shipyards.
Integrating AI in control and maintenance
Condition-based maintenance aims to predict maintenance thresholds and the need for shutdowns. Rather than predicting failure time, improvements or at least delays in deteriorating conditions can be achieved by incorporating the condition and stress of process equipment and machines into control. This simultaneously reduces the risk of unexpected damage.
Stabilizing control:
Continuous condition monitoring provides useful indicators and intelligent analyzers to support control. Through control execution, additional information is simultaneously obtained for condition monitoring. The goal here is continuous operation.
Optimizing and coordinating control:
Continuous condition monitoring could also play a central role in continuously compiling symptoms of failure for adaptation to changing conditions. Periodic condition monitoring leads to diagnostic and prognostic-based optimized and coordinated control. This involves periodic operational changes.
Adapting control strategy:
Condition monitoring and performance tracking are needed to adapt control strategies through diagnostics and prognostics, potentially involving short-term scheduling as well.
Real-time and updated information is required at all levels for decision-making. Integrating control and condition monitoring solutions aims to enable wise operations in changing conditions.
Challenges in applying AI
There are plenty of use cases, but many requirements and limitations must be addressed:
• Data quality and availability limit application development and potential use cases. Assembling all the necessary data in a balanced manner is difficult.
• Integration of AI solutions with condition monitoring systems requires careful validation. In practice, condition monitoring solutions must be assembled from components.
• Comprehensibility of AI solutions is essential for integration.
• Lack of reproducibility in computation also does not inspire confidence.
• Efforts towards standardization are present in all systems, but in the AI field, this is still far off due to insufficient validation and testing.
• Data management faces numerous challenges in maintaining extensive and multifaceted data in a balanced manner under changing conditions.
AI is well-suited for many applications in maintenance when application-specific requirements and limitations are factored into development. Data analysis is a valuable addition.
It’s also important to remember that reliable models and expertise do not need to be reinvented with AI: AI is applied selectively. The importance of expertise necessitates skilled personnel for various applications. The need for training does not diminish.
AI has developed over a long period
The key utilization of AI is based on the long development history of intelligent solutions. Since the 1950s, the model of brain structure has served as the basis for neuromorphic computing, where calculations occur in interconnected layers.

The Machine Awakens
Cognitive maintenance and the end of failure
Introduction: The Rise of Cognitive Maintenance
Industrial maintenance has long grappled with unplanned downtime and high repair costs. Reactive approaches fix machines only after they fail, while preventive methods replace parts on strict schedules, often unnecessarily. Predictive maintenance introduced data-driven insights that detect failures in advance, yet human decisions are still required to schedule and carry out repairs. Now, a paradigm known as cognitive maintenance is emerging, where machines are active contributors to their own health. Cognitive maintenance goes beyond simple alerts by allowing assets to self-diagnose problems and dynamically respond, reducing failures and extending operational life. Instead of running until something breaks, machines adapt to stressors and coordinate with other systems to optimize performance.
Key Technologies Enabling Cognitive Maintenance
Cognitive maintenance depends on multiple convergent technologies that move beyond passive monitoring toward autonomous action, including cognitive digital twins, edge computing, proprioception and self-aware robotics, the Industrial Metaverse, and mission-driven maintenance. By weaving these elements together, cognitive maintenance represents a new way of ensuring industrial reliability, cost-effectiveness, and long-term sustainability.
Traditional digital twins are passive digital copies of physical assets. They can reflect current conditions and provide analytics but rarely have the capacity to learn or evolve. Cognitive digital twins continuously update themselves by assimilating new sensor data, maintenance records, and operator feedback. They use this knowledge to optimize how a physical asset operates and predict maintenance needs.
Rather than simply sending alerts to human technicians who then plan repairs, cognitive twins autonomously initiate interventions and adjustments. While predictive maintenance focuses on detecting early signs of failure, cognitive maintenance takes a broader approach.
By combining AI with engineering expertise and real-time operational context, it allows the system to decide whether a machine should be serviced immediately or can safely continue functioning, thereby aligning maintenance decisions with business objectives. Because these twins can process large volumes of sensor readings at remarkable speed, they help avoid premature part replacements and catastrophic breakdowns. As a result, industries benefit from a new standard of reliability and cost savings.
Cognitive digital twins represent the unification of three traditionally separate domains: information technology for data management, operational technology for on-the-ground control, and engineering technology for the mechanical and design aspects of assets. By blending these domains, cognitive twins unlock real-time insights that go beyond flagging issues. These intelligent coordinators orchestrate maintenance activities, adapt machine behaviour, and maximize lifespan without the constant oversight of human technicians.
Edge computing contributes to cognitive maintenance by enabling instantaneous data processing at the asset level. In scenarios where a few milliseconds of delay could be critical, local processing capacity allows immediate adjustments,especially important for remote or high-risk applications. By reducing latency, machines can better self-regulate, halt operations if a serious fault is developing, or shift workloads to other systems in real time.
Proprioception and self-aware robotics expand on these capabilities by giving machines something analogous to a biological sense of muscle tension or joint stress. Embedded sensors within mechanical components can feel slight vibrations, detect small cracks, and sense wear before it escalates. The machinery autonomously responds, applying less force, distributing loads more evenly, or signalling that a part needs minor service before it fails completely. In high-stress industrial environments, this capacity for internal awareness saves both time and money.
The Industrial Metaverse provides immersive digital environments. By combining real-time data, historical records, and AI-driven simulations, this virtual ecosystem allows both machines and humans to practice responding to various failure modes.
Maintenance strategies can be tested and refined in a setting mirroring actual operations without risking real-world downtime or damage. This approach encourages experimentation and rapid innovation in maintenance practices.
Another advancement is mission-driven maintenance, where AI systems decide the best time for interventions based on overall operational priorities. If a facility is running at peak capacity, non-critical maintenance tasks can be postponed, while assets with higher risk of serious failure receive immediate attention. Thus, essential production targets are met without neglecting safety or assets’ long-term health. By integrating all these technological elements into a unified framework, industries can transform maintenance from a reactive chore into an active, strategic function.
Human-AI Symbiosis in Cognitive Maintenance
Although cognitive maintenance increases machine autonomy, human expertise is indispensable. AI systems excel at large-scale pattern recognition and real-time data processing, but humans have contextual awareness and strategic reasoning that machines cannot replicate. Cognitive maintenance aims to augment, not replace, technical professionals. AI assists by sifting through massive amounts of sensor data and proposing optimal repair schedules, while technicians verify these recommendations and handle complex troubleshooting.
This collaborative relationship becomes a feedback loop in which human actions and decisions improve AI models over time. When a technician modifies a recommended intervention or overrules an AI-generated insight, the system tracks and learns from that event. Gradually, predictive models become more refined, reducing false alarms and bolstering trust. Maintenance personnel begin to focus on higher-level tasks, such as orchestrating machine interactions, training AI systems, and ensuring automated suggestions do not compromise safety or ethical considerations.
Human intuition is particularly valuable for risk assessment and big-picture planning. Although machines can analyse data quickly and efficiently, only human operators can account for nuances such as emerging regulations, environmental impacts, and organizational strategies. Rather than executing countless repetitive checks, workers become supervisors, strategists, and mentors to intelligent systems. Together, human and machine intelligence form a resilient maintenance ecosystem capable of responding to unexpected challenges.
Case Studies: Cognitive Maintenance in Action
In manufacturing, an automotive plant applied AI-driven predictive models to robotic welders. Traditionally, robots kept working until scheduled maintenance or until a breakdown. With self-learning software, the machines began to detect wear, vibrational anomalies, and sensor readings that hinted at impending malfunctions. Production downtime decreased by a notable margin, and part replacements were timed more accurately, leading to cost savings, higher-quality welds, and fewer reworks.
In the transportation sector, a European rail operator equipped its rolling stock with AI-based monitoring systems. Real-time data on braking temperatures, axle stress, and wheel conditions allowed proactive interventions to be integrated into operational schedules. Maintenance tasks that previously occurred only during periodic inspections were now triggered whenever the data indicated an elevated risk.
The rate of in-service failures dropped significantly, improving reliability and passenger safety. The operator also observed better scheduling efficiency and optimized rolling stock usage.
In the energy sector, wind farms have embraced cognitive maintenance through AI-powered blade and turbine monitoring. Rather than adhering to fixed service intervals, turbines collect continuous data on wind conditions, vibration levels, and overall performance. They then automatically adjust blade pitch or rotational speed to reduce stress during turbulent weather. This helps prevent catastrophic mechanical failures, increases energy generation, and lowers maintenance costs. Operators have reported impressive improvements in annual power output and component longevity.
These examples illustrate the tangible benefits of combining AI-driven analytics, cognitive digital twins, and autonomous interventions. Across diverse applications, industries gain safer, more efficient, and more proactive approaches to maintaining complex systems.
Challenges and the Future of Cognitive Maintenance
Despite its promise, cognitive maintenance faces several barriers. One challenge lies in AI explainability. Many machine-learning models behave like “black boxes,” generating recommendations without giving clear rationales. Maintenance professionals may be reluctant to trust or act on AI suggestions they do not fully understand. Developing interpretable models and user-friendly interfaces is thus essential to broaden adoption.
Cybersecurity is another pressing issue. As machines become more interconnected and autonomous, the risk of malicious attacks increases. Protecting sensitive sensor data, preventing unauthorized access to operational controls, and ensuring system integrity demand robust, adaptive cybersecurity measures. Strategies such as encrypted data transmission and AI-driven intrusion detection are useful, but this is a constantly evolving field.
Legacy systems also pose difficulties. Many industries rely on older infrastructures with limited connectivity or outdated sensors.
Transitioning to cognitive maintenance involves significant investments in hardware upgrades, software platforms, and staff training. Workforce culture must shift to embrace AI-driven insights and new procedures. Companies who navigate these changes will position themselves for significant performance gains, outpacing those unable to adapt.
Looking to the future, advancements in computing will play a central role. Edge computing is already making machine-level intelligence more responsive, especially in remote environments. Emerging technologies such as quantum computing could vastly accelerate the processing of large datasets, unlocking near-instant predictive analytics. As these innovations mature, cognitive maintenance may evolve from its current emphasis on fault prediction into a realm of fully self-preserving and self-optimizing assets.
Conclusion
Cognitive maintenance transforms industrial reliability by empowering machines to anticipate, adapt to, and prevent their own failures, marking a decisive move away from human-led, reactive strategies towards ecosystems of autonomous, intelligent systems capable of self-preservation. However, human expertise remains vital in overseeing these operations. Technicians and engineers must ensure AI systems remain grounded in practical realities, ethical standards, and strategic objectives. The result is a symbiotic relationship where machines handle data-heavy diagnostics and routine adjustments, while people focus on complex problem-solving and broader coordination.
As industry moves toward greater autonomy and intelligence, cognitive maintenance will play a defining role in shaping the future of asset management. Over time, self-learning machines capable of continuous evolution will redefine the limits of what industrial systems can achieve.

Rallying Towards Cybersecurity
From five minutes to five seconds in remote connectivity. For a top-level rally team, every fraction of a second counts—not just on the track, but also in cybersecurity.
The TOYOTA GAZOO Racing World Rally Team (TGR-WRT) operates at the highest level of motorsport, competing in the World Rally Championship (WRC) across extreme and often remote locations. In this high-speed, high-pressure environment, secure and reliable access to data is critical. Whether at a service park deep in a Finnish forest or a remote mountain pass in South America, engineers, drivers, and support teams rely on instant access to vehicle telemetry, diagnostics, and strategic race data. Any delay can mean the difference between victory and defeat.
For years, TGR-WRT’s IT team struggled with the limitations of traditional network security solutions. VPNs and firewalls were cumbersome, slow, and increasingly vulnerable to cyber threats. The team needed a future-proof security solution that could protect sensitive engineering and race data while providing seamless, high-performance connectivity from anywhere in the world. That’s when they turned to Mintly Oy, a Finnish technology integrator, and Zscaler, a leader in cloud security.
Recognizing the need for a modern security architecture, TGR-WRT partnered with Mintly to explore Zero Trust security—an approach that eliminates traditional network perimeters and grants access based on identity and context. After a successful proof-of-concept, the team deployed the Zscaler Zero Trust Exchange™, a cloud-native security platform designed to protect users, applications, and data without the limitations of traditional security models.
The results were immediate and transformative. Before adopting Zscaler, it could take up to five minutes for a team member to boot up their laptop, connect to a VPN, and access the data they needed. Now, that process takes just a few seconds. Network stability and performance improved significantly, especially in remote locations where reliable connectivity is often a challenge. At the same time, false positives related to URL filtering were drastically reduced, and firewall-related issues that had plagued the team for years were eliminated.
Riku Nykänen, Information Security Officer at TGR-WRT, describes the impact: “Zscaler simplifies our security architecture and ensures that our teams have secure, seamless connectivity no matter where they are. This makes a real difference in our races, where every tenth of a second counts.”
Uncompromising Security. During a rally, data flows constantly between the cars, engineers, and headquarters. Vehicle telemetry, tire pressure data, and engine diagnostics must be transmitted instantly so that real-time adjustments can be made to optimize performance. Any disruption in connectivity could lead to missed opportunities for crucial race decisions.
With Zscaler, TGR-WRT has built an environment where sensitive data can be transmitted securely and efficiently across multiple locations.
By replacing traditional VPNs with Zscaler Private Access™ (ZPA™), the team now enjoys direct, secure connections to private applications without exposing the network to potential cyber threats. Zscaler Internet Access™ (ZIA™) provides an additional layer of security, ensuring that all internet and SaaS application traffic is protected against cyber threats.
Jussi Luopajärvi, IT Manager at TGR-WRT, has seen firsthand how the transformation has enhanced the team’s operations.
“Zscaler blew our minds. User productivity has skyrocketed. The time it takes for users to turn on their laptops and start doing productive work has dropped from five minutes to a few seconds. Network performance in remote locations is better than ever, and the security challenges we faced before have disappeared,” he says.
Strengthening OT security in motorsport. While the primary focus of the deployment was IT security, TGR-WRT also recognized the growing cybersecurity risks in OT (Operational Technology) networks. Modern motorsport relies heavily on connected systems, IoT devices, and real-time telemetry—all of which must be protected from cyber threats.
Timo Aarvala, CEO of Mintly, explains the urgency of OT security in today’s landscape: “OT cybersecurity challenges have escalated, making it critical to protect these networks from cyber threats. We need to focus on network segmentation, device updates, remote access management, and continuous monitoring. By implementing these measures, we can ensure that OT networks remain secure and fully operational. The reality is that OT security lags IT security by decades, and many organizations are now struggling to define responsibilities and integrate cybersecurity fundamentals into their production networks.”
As cyber threats are targeting industrial control systems and automotive technology increase, TGR-WRT understood that protecting both IT and OT environments is crucial to maintaining a competitive edge. Through its Managed Security Services, Mintly helped TGR-WRT bridge the gap between IT and OT security by implementing network segmentation, continuous monitoring, and secure remote access. This ensures that all aspects of rally operations from vehicle diagnostics to engineering remain secure and uncompromised.
Since implementing Zscaler’s security solutions, TGR-WRT has processed over 262 million transactions and 13.7 TB of traffic in just three months, a staggering 1400% increase from the previous year. Over the same period, Zscaler detected and blocked approximately 3 million security policy violations, reinforcing the effectiveness of the new security architecture.
For a team that competes at the highest level of motorsport, every fraction of a second counts, not just on track, but in cybersecurity as well. By embracing a Zero Trust approach with Mintly and Zscaler, TGR-WRT has set a new benchmark for secure, high-performance operations in the world of motorsport. As the team continues to innovate and push the limits of rallying, its cybersecurity strategy has evolved to match its ambitions, proving that speed, security, and success go hand in hand.
