The true cost of AI: A reality check for fund managers

AI now comes with a meter running. Join our expert panel to explore how consumption-based pricing is reshaping AI adoption and how to prove it’s delivering measurable value.

The vast majority of financial service firms hold cyber insurance, but until an incident occurs, they don’t know if their insurer will actually pay. Here’s the uncomfortable truth: a significant number of cyber insurance claims are denied, and not for obscure reasons.

So, why does this happen? More importantly, how can operational leaders in financial services avoid falling into the same trap? Let’s explore the top 6 reasons cyber insurers aren’t paying out.

1. Missing or weak security controls

This shouldn’t shock anyone, yet it remains the number one reason claims fail. Roughly a quarter of rejected claims are linked to controls that were missing, incomplete, or “in progress but not actually finished.”

Insurers aren’t asking for miracles — just the basics they consider non-negotiable:

  • MFA everywhere is important (not just Microsoft 365)
  • Patch management that doesn’t rely on “we’ll get to it next quarter”
  • Endpoint detection and response (EDR) is actually turned on and covers the estate
  • Security monitoring that sees more than yesterday’s logs
  • Proper remote access controls (VPN alone does not count)

Insurers don’t care about your roadmap. They care about what was in place before the incident. If MFA rollout is “almost done,” the insurer will politely (or not so politely) disagree.

2. Inaccurate or overstated disclosures

Cyber insurance applications are essentially legal documents disguised as questionnaires. The temptation is to paint a slightly rosier picture:

  • “Yes, we have MFA everywhere.”
  • “Yes, our patching is up to date.”
  • “Yes, we monitor all critical systems.”

What’s the problem? Insurers now verify. If anything on the form is even slightly inaccurate, they can and increasingly do declare the policy void. Even unintentional errors count, and many firms get caught out because they assume “mostly true” is close enough. Unfortunately, it isn’t.

3. Reporting the incident too late

Most cyber policies require rapid notification — often within 24–72 hours of first noticing something’s wrong.

The challenge for financial services firms is that incident reporting is complicated. Legal, compliance, risk, IT, security, the board, and sometimes external regulators all need a say. By the time everyone signs off on the wording, the deadline can easily pass.

Insurers won’t hesitate to decline a claim that arrives too late. A clear incident response plan is essential, including the key question: “Who do we call first, and how fast?”

4. Policy exclusions nobody noticed until it was too late

Cyber policies today are full of exclusions. Some are reasonable, and some could be classed as… creative.

Common ones include:

  • Anything that looks even remotely like a nation-state attack
  • Social engineering fraud (unless you paid extra for it)
  • Losses linked to unpatched, known vulnerabilities
  • Insider misconduct
  • Cryptocurrency-related incidents

Many firms only notice these exclusions at the worst possible moment — while trying to file a claim.

5. Thinking you don’t need insurance because it’s “outsourced”

Many clients assume that because their IT is outsourced or hosted in the Cloud, the third party fully covers them. They often fail to properly analyse the shared responsibility model and overlook the need to insure any assets within their environment, such as their tenant, network, or data. When gaps exist, risks can fall between the cracks, and insurance may not pay.

6. Filing under the wrong section of the policy

This one surprises many people. A ransomware attack can touch multiple policy areas — extortion, business interruption, breach response, and forensic costs.

If you file under the wrong clause, insurers can reject or delay your claim. More organisations are now involving specialist brokers or legal counsel during incidents to ensure claims are filed correctly.

So, what’s coming next from insurers?

The direction of travel is clear:

1. Insurance + cybersecurity services merge

Insurers are increasingly bundling incident response, forensics, legal support, and monitoring. Policies are becoming part product, part service.

2. Continuous compliance

No more “tick the box once a year.” Insurers want ongoing assurance that controls remain active, not just promised.

3. AI-driven underwriting

Expect insurers to scan your external footprint, analyse your exposure, and assess your real-time risk posture using AI. Think of it as continuous security due diligence, whether you like it or not.

What financial services leaders should do now

Cyber insurance can still be hugely valuable, but only if firms approach it with their eyes open.

To avoid denied claims:

  • Ensure critical controls (MFA, EDR, patching) are fully deployed and documented
  • Review all disclosures carefully — “mostly true” isn’t safe
  • Build insurer notification into your incident response plan
  • Audit exclusions — you may be surprised
  • Get expert support when filing claims

Cyber insurance isn’t a safety net anymore. It’s a partnership, and like any partnership, it only works if both sides uphold their end.
