Summary Points
- Cyber insurance claims for ICS incidents are increasingly complex and often denied due to exclusions linked to nation-state or ‘war-like’ attacks, with insurers demanding extensive data and risk profiles that many organizations find challenging to provide.
- Insurers are refining underwriting models to incorporate OT-specific risks, including legacy equipment and operational constraints, leading to higher premiums and stricter control requirements, often influenced by the need for detailed asset inventories and cybersecurity practices.
- Despite growing efforts to incentivize OT security measures through premiums and coverage enhancements, many insurers’ ‘incentives’ are criticized as superficial risk-shifting tactics, with detailed visibility demands potentially undermining insurability and fostering an illusion of risk management.
- The evolving insurance landscape emphasizes resilience and standards compliance, but true risk reduction relies on measurable, pre-loss forensic data and operational readiness—highlighting a gap between insurers’ marketing metrics and actual risk mitigation effectiveness.
The Core Issue
The industrial sector faces a complex and often hostile environment when it comes to filing cyber insurance claims, especially for incidents involving industrial control systems (ICS). Recent changes in policies, notably Lloyd’s of London’s 2023 exclusion of coverage for state-backed cyberattacks, have heightened the challenge, as proving nation-state involvement remains technically difficult and insurers frequently deny claims based on narrowly defined “war” clauses. Industry experts, such as those from Marsh McLennan and Ariel Re, highlight that while insurers are demanding more detailed information—like asset inventories and risk profiles—they often lack the technical expertise or legal frameworks necessary to accurately assess OT-specific risks, leading to conflicts, denials, or exaggerated exclusion clauses. This creates a frustrating paradox: organizations are pushed to enhance their cybersecurity, sometimes at great cost, to qualify for coverage, yet insurance policies remain riddled with ambiguities and exclusions that can leave them unprotected precisely when they are most vulnerable.
Simultaneously, insurers are attempting to shape OT security standards through incentives, underwriting adjustments, and scrutiny of resilience metrics, such as containment speed and compliance with industry standards like IEC 62443. However, many experts criticize these efforts as superficial, arguing that true resilience is only measurable by an organization’s ability to absorb and recover from losses, not by checkbox frameworks. Furthermore, the pursuit of visibility—such as detailed asset inventories and software bills of materials—raises legal and operational concerns, as sharing sensitive data can jeopardize proprietary information and operational stability. Ultimately, the industry’s evolving approach reflects a tension between insurability and technical competence, often leaving industrial organizations navigating an opaque landscape where coverage is uncertain, risks are poorly understood by underwriters, and the true cost of security often outweighs the perceived benefits of insurance incentives.
What’s at Stake?
Cyber risks in industrial environments have grown exponentially, fueled by complex vulnerabilities in legacy systems, supply chain weaknesses, and inadequate patching, making insurance claims increasingly difficult due to widespread exclusions for state-backed or ‘war-like’ cyberattacks. Insurers are tightening underwriting standards, demanding detailed asset inventories, risk profiles, and implementing incentives for OT-specific safeguards like network segmentation and monitoring—aimed at reducing both the likelihood and severity of breaches. However, the intricate nature of OT systems, limited forensic visibility, and attribution challenges—especially when linking attacks to nation-states—complicate claims validation and coverage enforcement, often resulting in denials, exclusions, or reduced payouts that leave organizations exposed during crises. Moreover, the evolving insurance landscape influences operational decisions, prompting investments in security controls and resilience metrics, yet remains hampered by outdated underwriting models and a lack of specialized expertise, leaving a dissonance between perceived coverage and actual risk, and highlighting a critical need for more sophisticated, transparent, and domain-specific risk management approaches in industrial cybersecurity.
