Introduction: Why Cyber Insurance Isn’t a Silver Bullet

Cyber insurance is often seen as a safety net for businesses, protecting them from financial losses after cyberattacks, data breaches, and ransomware incidents. However, many businesses are caught off guard when their claims are denied—often due to hidden exclusions buried in the fine print.

📌 Over 40% of cyber insurance claims are denied due to policy exclusions.
📌 Many businesses assume they are covered for ransomware, data theft, and system outages—but exclusions often limit or deny payouts.
📌 Regulators are now scrutinising cyber insurance contracts, as unclear exclusions leave businesses exposed to major financial risks.

🔹 The challenge? Most companies don’t fully understand what their cyber policy does NOT cover—until it’s too late.
🔹 This article breaks down common cyber insurance exclusions, why they exist, and how businesses can avoid unexpected claim denials.

1️⃣ What Are Cyber Insurance Exclusions?

Cyber insurance exclusions are specific conditions or events that the insurer will NOT cover. These exclusions limit liability, meaning businesses may have to cover certain cyber losses themselves.

While insurers promote broad coverage, the reality is that many high-impact cyber events fall under exclusions, leaving businesses with unexpected financial exposure.

💡 Example: A company assumes it is covered for ransomware attacks but later discovers that paying the ransom is an exclusion, forcing them to absorb the financial loss.

2️⃣ The Most Common Cyber Insurance Exclusions Businesses Should Watch For

🔹 1. Acts of War & Nation-State Cyber Attacks

📌 What’s excluded?
Cyberattacks linked to nation-states, espionage, or geopolitical conflicts are often excluded from coverage.

📌 Why?
Insurers argue that state-sponsored attacks are acts of war, similar to how physical war damage is excluded from property insurance.

💡 Example: In the 2017 NotPetya attack, many companies had their claims denied because insurers classified the attack as a state-sponsored cyber war incident.

✔ How to protect your business:

  • Ask your insurer for clear definitions of “nation-state attacks”.
  • Negotiate endorsements or coverage add-ons that reduce this exclusion’s impact.

🔹 2. Ransomware Payments & Extortion Demands

📌 What’s excluded?
Some policies do not cover ransom payments if businesses choose to pay hackers after a ransomware attack.

📌 Why?
Insurers do not want to encourage ransom payments, as it incentivises cybercriminals to attack more businesses.

💡 Example: A UK-based law firm was hit by ransomware and expected insurance to cover the £250,000 ransom—but their policy excluded any payments to cybercriminals.

✔ How to protect your business:

  • Ensure ransomware response costs are covered, including forensic investigations, recovery efforts, and legal expenses.
  • Invest in offline backups and disaster recovery planning to avoid the need to pay ransoms.

🔹 3. Human Error & Social Engineering Attacks

📌 What’s excluded?
Some cyber policies exclude coverage for financial losses caused by employee mistakes, such as falling for phishing scams or fraudulent wire transfers.

📌 Why?
Insurers argue that human error is preventable and that businesses should train employees to spot scams.

💡 Example: A finance team mistakenly wired £500,000 to fraudsters after receiving a fake invoice, but insurance denied the claim, citing an exclusion for social engineering fraud.

✔ How to protect your business:

  • Look for specific coverage for social engineering and business email compromise (BEC) scams.
  • Train employees on cybersecurity awareness and phishing detection.

🔹 4. Unpatched Software & Outdated Security Measures

📌 What’s excluded?
If a cyberattack occurs due to outdated systems, unpatched software, or weak security controls, insurers may deny the claim, arguing that the business failed to follow basic cybersecurity hygiene.

📌 Why?
Insurers expect companies to maintain basic security controls, like patching vulnerabilities, using multi-factor authentication (MFA), and following industry best practices.

💡 Example: A company using an outdated version of Microsoft Exchange was hit by a data breach. Their cyber insurer refused to cover the costs, citing failure to patch known vulnerabilities.

✔ How to protect your business:

  • Ensure regular security updates and patching policies.
  • Implement MFA, endpoint protection, and access controls to meet insurer requirements.

🔹 5. Cloud & Third-Party Service Failures

📌 What’s excluded?
If a cyber incident is caused by a third-party provider, such as a cloud service (AWS, Microsoft Azure, Google Cloud) or SaaS vendor, insurers may deny coverage, arguing that the third party is responsible.

📌 Why?
Insurers may shift liability to the cloud provider, leaving businesses caught in a dispute over who is responsible for damages.

💡 Example: A SaaS startup suffered a major outage due to a breach at their cloud provider, but their insurer denied the claim, stating third-party risks were excluded.

✔ How to protect your business:

  • Ensure your policy covers cloud-related security failures.
  • Review third-party risk agreements and consider cybersecurity liability clauses in contracts.

🔹 6. Insider Threats & Employee Misconduct

📌 What’s excluded?
Cyber incidents caused by disgruntled employees, internal sabotage, or intentional policy violations may not be covered.

📌 Why?
Insurers classify malicious insider activity as an employment risk rather than a cybersecurity issue.

💡 Example: A former employee stole customer data and sold it on the dark web. The company filed a cyber insurance claim, but it was denied due to an exclusion for insider threats.

✔ How to protect your business:

  • Implement strict access controls and monitoring for sensitive systems.
  • Ensure employee exit procedures include revoking access immediately.

3️⃣ How to Avoid Unexpected Cyber Insurance Exclusions

✅ 1. Read the Fine Print Before Buying a Policy

🔹 Ask insurers for a full list of exclusions upfront.
🔹 Clarify definitions of key terms (e.g., “nation-state attack,” “human error,” “insider threat”).
🔹 Negotiate additional coverage where needed.

✅ 2. Ensure Your Cybersecurity Meets Insurer Requirements

🔹 Patch all software vulnerabilities regularly.
🔹 Enforce MFA on all user accounts.
🔹 Implement security awareness training for employees.

✅ 3. Work with Legal & Risk Experts to Assess Policy Gaps

🔹 Engage a cybersecurity lawyer or insurance broker to review policy terms.
🔹 Assess vendor and cloud service contracts for liability gaps.
🔹 Align your risk management strategy with policy coverage.

4️⃣ Final Thoughts: Cyber Insurance Is Only Part of the Solution

💡 Cyber insurance is a critical safety net, but it’s not a substitute for strong cybersecurity practices.

To avoid costly surprises, businesses must:
✔ Understand policy exclusions before buying coverage.
✔ Meet insurer security requirements to prevent claim denials.
✔ Invest in proactive cybersecurity defences (MFA, encryption, risk monitoring).
✔ Ensure third-party risks and cloud services are covered in policies.

🚨 A cyber insurance policy full of exclusions won’t help when disaster strikes—get clarity before it’s too late.

Cyber Insurance Exclusions: What Businesses Need to Know

Introduction: The Hidden Gaps in Cyber Insurance

Cyber insurance is often seen as a financial safety net for businesses facing cyberattacks, data breaches, and ransomware incidents. However, not all cyber risks are covered. Many companies wrongly assume their policy will pay out after an incident, only to find that exclusions leave them without financial support.

📌 62% of businesses with cyber insurance have had claims denied due to exclusions.
📌 80% of cyber insurance policies contain exclusions for human error and unpatched systems.
📌 Regulatory fines and reputational damage are often not covered by standard policies.

🔹 The challenge? Businesses don’t always read the fine print until it’s too late.
🔹 Understanding cyber insurance exclusions is critical to ensuring your organisation isn’t left exposed.

This article will break down:
✔ What cyber insurance does and doesn’t cover
✔ The most common exclusions that lead to claim denials
✔ How businesses can reduce risk and avoid coverage gaps

1️⃣ What Does Cyber Insurance Cover?

Cyber insurance helps businesses recover financially from cyberattacks, breaches, and IT security failures. Policies typically cover:

✅ Data Breach Costs – Investigations, legal fees, and customer notifications.
✅ Business Interruption – Financial losses due to downtime from an attack.
✅ Ransomware Payments – Reimbursement for ransom payments (subject to conditions).
✅ Incident Response & Recovery – Costs for forensic investigations, IT repairs, and crisis management.
✅ Legal Defence – Protection against lawsuits from affected customers or regulators.

📌 Sounds comprehensive? The reality is more complicated—many policies have hidden exclusions.

2️⃣ The Most Common Cyber Insurance Exclusions

Many businesses assume that if they suffer a cyberattack, their insurer will cover the damages—but that’s not always the case. Here are the key exclusions that can leave companies without coverage:

🔹 1. Human Error & Employee Negligence

📌 The risk: If an employee falls for a phishing scam or accidentally exposes sensitive data, the insurer may refuse to pay out.
📌 Example: A finance employee wires money to a fraudulent account due to a Business Email Compromise (BEC) scam—but because it was human error, the claim is denied.

💡 Solution: Implement employee cybersecurity training and phishing awareness programs.

🔹 2. Unpatched Systems & Poor Cyber Hygiene

📌 The risk: If your systems were unpatched or outdated when an attack occurred, insurers may deny the claim for failing to follow basic security protocols.
📌 Example: A business suffers a ransomware attack due to an unpatched vulnerability, but the insurer refuses to pay because the company failed to apply security updates.

💡 Solution: Maintain a structured patch management program and document security updates.

🔹 3. Acts of War & Nation-State Cyberattacks

📌 The risk: Many policies exclude cyberattacks linked to foreign governments or nation-state actors.
📌 Example: If your business is hit by an attack attributed to a state-backed hacking group (e.g., APT29, Lazarus Group, or Hafnium), the insurer may classify it as an “act of war” and deny the claim.

💡 Solution: Work with insurers offering nation-state attack coverage and monitor geopolitical cyber threats.

🔹 4. Regulatory Fines & GDPR Violations

📌 The risk: Many businesses assume their policy covers fines from GDPR, CCPA, or other data protection laws—but most insurers explicitly exclude regulatory penalties.
📌 Example: A healthcare company is fined £500,000 for a GDPR violation following a data breach. The insurer refuses to cover the cost because regulatory fines are excluded from the policy.

💡 Solution: Ensure your compliance policies align with regulatory requirements to prevent fines.

🔹 5. Pre-Existing Security Vulnerabilities

📌 The risk: If an attack exploits a known vulnerability in your systems that was not fixed, insurers may argue that the company was reckless and refuse to pay.
📌 Example: A business was breached due to an exposed API that had been flagged six months earlier. The insurer denies the claim because the company failed to remediate the issue in time.

💡 Solution: Conduct regular security audits and address vulnerabilities immediately.

🔹 6. Third-Party Vendor Breaches

📌 The risk: If a third-party supplier, vendor, or cloud provider suffers a breach that impacts your business, some insurers won’t cover the losses.
📌 Example: Your business relies on a SaaS provider that gets hacked, exposing your customer data. Your insurer denies the claim because the breach occurred outside your organisation.

💡 Solution: Ensure vendors have strong security controls and review third-party cyber risk insurance.

🔹 7. Insider Threats & Rogue Employees

📌 The risk: If an employee intentionally leaks data or sabotages systems, insurers may classify it as internal fraud and refuse coverage.
📌 Example: A disgruntled IT admin deletes critical databases and wipes backups. The insurer argues that it was an intentional act and denies payment.

💡 Solution: Implement Zero Trust security principles and strict access controls for privileged accounts.

3️⃣ How to Ensure Your Business is Properly Covered

✅ 1. Review Your Cyber Insurance Policy in Detail

🔹 Ask your insurer for a full list of exclusions and clarify coverage gaps.
🔹 Request rider policies (additional coverage) for excluded risks.
🔹 Ensure legal teams review the policy before signing.

✅ 2. Align Security Controls with Policy Requirements

🔹 Maintain strong cyber hygiene (patching, MFA, encryption).
🔹 Implement security awareness training for employees.
🔹 Use endpoint detection and response (EDR) tools to prevent breaches.

📌 Tip: Insurers increasingly require compliance with frameworks like NIST, ISO 27001, and Cyber Essentials—ensure your security posture meets their standards.

✅ 3. Strengthen Your Vendor & Supply Chain Risk Management

🔹 Conduct third-party risk assessments to ensure vendor security.
🔹 Require vendors to have cyber insurance coverage.
🔹 Implement contract clauses that hold vendors accountable for breaches.

📌 Tip: Use continuous monitoring tools to track vendor cybersecurity risks in real time.

4️⃣ Final Thoughts: Cyber Insurance is Not a Silver Bullet

Cyber insurance can’t replace strong cybersecurity practices. While it provides financial protection, it comes with exclusions that businesses must fully understand.

To avoid cyber insurance claim denials:
✔ Review policy exclusions carefully before purchasing.
✔ Ensure compliance with security standards required by insurers.
✔ Patch vulnerabilities and maintain strong access controls.
✔ Work with vendors who follow strong cybersecurity practices.

🚨 A well-prepared cybersecurity strategy reduces risks AND improves your ability to claim when disaster strikes.
