Frequently Asked Questions

What does cyber insurance cover?
Typical cyber insurance covers: data breach response costs, ransomware payments and recovery, business interruption from cyber attacks, regulatory fines and penalties, third-party liability, credit monitoring for affected customers, and forensic investigation costs.
Is cyber insurance mandatory in the UK?
No, but the ICO and NCSC strongly recommend it. Some contracts and industry regulations effectively require it. Under GDPR, businesses must have adequate security measures, and insurance can be part of that.
What affects my premium?
Key factors include: annual revenue, employee count, industry sector, volume and sensitivity of data held, existing cyber security measures, claims history, and the cover level and excess chosen.
What is not covered?
Common exclusions include: known vulnerabilities not patched, acts of war or state-sponsored attacks, prior breaches not disclosed, social engineering losses (sometimes), and reputational damage that cannot be quantified.
How can I reduce my premium?
Implement strong cyber security: multi-factor authentication, regular patching, employee training, encrypted backups, incident response plan, and Cyber Essentials certification. Some insurers offer 10-20% discounts for Cyber Essentials Plus.
What is Cyber Essentials?
Cyber Essentials is a UK government-backed scheme that helps organisations protect against common cyber attacks. Certification costs around £300-£500 and demonstrates baseline security. Cyber Essentials Plus includes independent testing.
