Why Cyber Insurance is Not a Substitute for Cyber Risk Management
Understanding the role of cyber insurance in the context of cyber risk management is critical for financial services firms. Cyber insurance does not prevent attacks or solve cybersecurity problems. Instead, its role is to provide a final financial safety net for residual risks after robust cybersecurity measures have been implemented. Relying solely on insurance can leave firms vulnerable to operational disruption, reputational damage, and regulatory consequences.
Cyber Insurance Isn’t Enough
A cyber insurance policy may provide some comfort, but it does not stop your firm from being targeted or from suffering a serious cyber breach and cannot prevent the operational and reputational fallout from a breach.
After an attack, firms often face multiple challenges that insurance cannot fix. Senior management may have to work around the clock to maintain operations while core systems are offline. Staff can be locked out of essential tools, unable to perform their roles. Communicating the breach to clients, staff, regulators, and even the media can be complex, particularly when usual channels are unavailable. There is also the internal strain: morale can suffer, and blame can emerge. Negotiating with attackers or remediating vulnerabilities that allowed the attack in the first place will strain the firm’s internal resources.
The National Cyber Security Centre (NCSC) emphasises that cyber insurance is not a substitute for proactive cybersecurity:
“Cyber insurance will not instantly solve all your cyber security issues, and it will not prevent a cyber breach/attack. Organisations must continue to put measures in place to protect what they care about.”
The Importance of Cyber Risk Management Matters in Financial Services
The financial services sector is high risk when it comes to cyber security. Criminals have found a variety of methods, including email account takeover and ransomware attacks to be particularly profitable in a business where data protection, client confidentiality and secure financial and operational systems are crucial.
Regulatory and legal obligations
Firms must protect data and be operational resilient. They must carry out regular risk assessments, implement robust governance frameworks, and have clear policies and training for staff. Technology and data must be secured, and controls regularly tested. Essential services and supply chain risks must be understood and managed. Incident response plans should be in place and rehearsed. Evidence of compliance is crucial, as failure to meet legal and regulatory requirements can result in substantial fines.
Data breaches
The ICO has taken robust action against organisations, across all sectors, who have failed to implement appropriate technical and organisational measures. The cases highlight the need to take into account not just UK GDPR but also FCA regulatory obligations and FCA guidance; “relevant industry standards of good practice” such as ISO27001, the National Institute of Standards and Technology; and guidance from ICO itself as well as NCSC. Anyone interested in the ICO’s approach should read the cases of Interserve (fine £4.4m), Advanced (fine £3.07m) and 23andMe (fine £2.31m).
Breaches of client confidentiality
Once sensitive client information is compromised, restoring confidence is extremely challenging. Important clients may question a firm’s ability to protect their interests, potentially resulting in lost business. No insurance can repair the erosion of trust or reputational damage.
Business disruption
If you are breached, expect extensive operational downtime. Most backups we examine would not survive a ransomware attack – and even in the best-case scenario, it will be many weeks before anything like normal service is resumed, and months to restore everything. Some firms never recover.
Cybersecurity is a Board-Level Responsibility
Cybersecurity is not an IT concern; it is a strategic, board-level issue. Directors or partners are accountable for cyber risk management, ensuring that the firm has the right systems, policies, and reporting in place. The senior leadership team will face the consequences of any breach, answering to regulators, clients, and other stakeholders.
The Government’s Cyber Governance Code of Practice stresses that cyber risk should have the same prominence as financial or legal risks, and responsibility for it must be clearly assigned at board level. Cyber risk should feature in regular board discussions, alongside other strategic risks.
The Role of Independent Assurance
Proper cyber risk management requires independent assurance carried out by genuine cyber security specialists with in-depth knowledge of the latest security risks and experience of the attacks taking place in your sector. Having IT providers make their own homework is a non-starter from both a compliance and assurance perspective.
Conclusion
Cyber insurance has a place in risk management. It can cover some costs, but it cannot prevent attacks or repair all of the fallout. Financial services firms need proactive, board-level cyber risk management and independent assurance to protect data, meet regulatory obligations, safeguard reputation, and keep operations running. Insurance alone is never enough.
