The Hidden Dangers of Operational Technology Risks in Data Centres (2026)

Imagine a world where the very systems keeping our data centers humming—managing power, temperature, and security—could silently unravel, leading to chaos that ripples through healthcare, banking, and even government operations. That's the hidden danger of operational technology (OT) risks in data centers, a critical yet frequently underestimated piece of risk management. But here's where it gets intriguing: these invisible threats aren't just about tech glitches; they blend physical safety with digital vulnerabilities in ways that could spark heated debates on how we protect our modern world. Let's dive deeper into this fascinating yet urgent topic, peeling back the layers so even newcomers can grasp the essentials.

Operational technology, or OT, plays a pivotal role in data center operations, often flying under the radar compared to more visible data management concerns. You can learn more about specialized data center risk management at Marsh's dedicated page (https://www.marsh.com/en-gb/industries/technology/expertise/data-centre-insurance-and-risk-management-services.html). Essentially, data centers depend on OT systems to oversee and regulate industrial machinery and processes, including energy management systems (EMS) and building management systems (BMS). These setups employ controllers and sensors to fine-tune everything from electrical power distribution to climate control and access restrictions. Industrial control systems (ICS) like these are the unsung heroes of efficiency, but they also open the door to a trio of perils: physical hazards, operational hiccups, and cybersecurity weak spots.

These dangers can arise from a variety of sources, such as software hiccups, slip-ups by people, malicious actors like hackers, or a mix of targeted and random cyber incidents—each with the power to throw critical infrastructure into disarray. Data centers form the backbone of indispensable services like communication networks, medical facilities, financial institutions, and public administration. So, any OT-related incident could trigger far-reaching fallout, jeopardizing the dependability and security of services we all rely on daily, from emergency calls to online banking. And this is the part most people miss: the cascading effects could amplify into societal disruptions, challenging our assumptions about technological reliability.

The good news? Adopting forward-thinking OT risk management tactics can fortify these vital hubs. Such proactive steps build stronger defenses against shifting technological threats, ultimately shielding the foundation of our contemporary infrastructure.

Now, let's zoom in on OT specifics for data centers. These facilities encounter a range of potential loss situations sparked by their internal systems, often triggered by OT mishaps—whether it's a simple operational blunder or a full-blown cyber assault. A rising concern is the tangible harm and subsequent downtime these events can inflict on the data center itself.

This underscores the fusion of digital tools with the tangible world, where OT governs essential physical assets inside data centers. Picture this: a software bug or a human mistake might bypass safety measures, sparking fires, floods, or breakdowns in temperature regulation. Or consider a cyberattack honing in on heating, ventilation, and air conditioning (HVAC) systems, throwing off climate control and inflicting harm on servers and hardware. These scenarios could result in everything from busted equipment to stalled operations, hefty financial hits, and tarnished reputations.

While recorded cases of such physical losses are still uncommon, the expanding global network of data centers, their growing status as fundamental infrastructure, and the deeper weaving of OT into their physical and procedural fabrics all crank up the overall danger. For instance, think of a data center in a bustling city where a single OT failure could cascade into a blackout affecting millions— a real-world illustration of how interconnected our systems have become.

Delving into the intricate nature of these risks reveals a maze of challenges. The vagueness surrounding threats to data centers, especially at the crossroads of cyber and OT worlds, comes from their tangled interconnections, unclear accountability or oversight, and the risk of domino-like, unforeseeable consequences. This shapes a dynamic and ever-changing danger zone where standard risk evaluation tools might not suffice.

The blend of tech and the physical realm also complicates traditional insurance approaches. A lone incident causing both material destruction and intangible losses in a data center isn't typically handled by one blanket policy. For example, cyber insurance usually addresses data theft, extortion, and downtime from a digital attack but often skips over property harm from the same event. And here's where it gets controversial: traditional property insurance doesn't always extend to physical damage triggered by cyber causes, leaving a glaring hole in coverage that might surprise even seasoned business owners. Does this mean our insurance models are lagging behind the technology they aim to protect? It's a debate worth having—could this gap encourage companies to innovate their own safeguards, or does it demand a radical overhaul of policy frameworks?

As a result, data center operators frequently turn to a multi-layered insurance strategy, combining customized policies for items like property harm, operational halts, engineering perils, service level agreements (SLAs), and digital threats.

Insurance offerings for data centers are adapting to match the ballooning scale, intricacy, and hazard profiles of our digital backbone.

Property Damage and Business Interruption (PDBI) coverage equips operators with funds to fix or swap out ruined gear and offset interruption expenses.

When PDBI isn't feasible, standalone physical cyber programs could fill the void. Specialized cyber-physical damage options, crafted for incidents where digital attacks lead to real-world harm, represent a novel and developing area of the insurance world, offering robust shields for data centers.

A fresh Marsh analysis, co-created with Dragos—The 2025 OT Security Financial Risk Report (https://www.dragos.com/2025-ot-security-financial-risk-report)—explores the monetary toll of OT-involved cyber disruptions and sheds light on their changing character. Leveraging this knowledge, Marsh is crafting bespoke solutions and partnering with insurers to roll out holistic 'core' PDBI options that fit data center operators' unique demands.

With data center tech becoming more advanced and demand surging, risk landscapes will keep morphing, calling for cutting-edge security and management techniques. Plus, given the immense asset values locked in digital infrastructure, locking in sufficient insurance capacity is non-negotiable. Thus, the insurance and risk scene must evolve ahead of the curve to protect data center resources and maintain seamless business flow.

To wrap this up, it's helpful to clarify some key terms that often get mixed up: operational technology risks, cyber events, and cyber risks. These are interconnected but separate ideas.

Operational technology (OT) risks target the industrial control systems and physical operations powering critical infrastructure. They encompass material harm, safety dangers, and operational stoppages from cyber breaches, equipment failures, or aging legacy setups. Think issues like ransomware, unsecured remote logins, poor visibility into OT networks, and the blending of IT and OT worlds—these can endanger lives, stall functions, and rack up costs.

Cyber events are the actual happenings or occurrences tied to digital actions that inflict or could inflict damage. This includes targeted assaults or breakdowns like data leaks, ransomware hits, denial-of-service barrages, system crashes, or unauthorized intrusions. These are the concrete moments that set off insurance payouts.

Cyber risks, on the other hand, denote the prospective dangers or weak points that might pave the way for cyber events. They capture the chance of incidents happening and the linked vulnerabilities to monetary losses, workflow interruptions, image harm, or legal fines. Cyber risks paint the bigger picture of threats, from cunning hacker methods to system flaws and internal susceptibilities.

Insurance products evaluate and price these cyber risks, covering damages from cyber events. Grasping these nuances empowers insurers and policyholders to tackle exposures head-on and handle incidents skillfully. But here's a thought-provoking twist: in an era where cyber risks evolve faster than policies can adapt, are we underestimating how OT vulnerabilities could redefine 'critical infrastructure'? Share your take in the comments—do you agree that insurance needs to get more aggressive, or is there a counterpoint we've missed? We'd love to hear your views!
