Business cyber insurance can help with certain costs after incidents such as data breaches, ransomware, phishing or business interruption, depending on the policy. Cover may include forensic investigation, data recovery, customer notification, public relations support and some legal expenses, but exclusions and limits vary widely. Insurers may require security measures such as multi-factor authentication, backups and staff training before offering cover or responding to a claim. Compare the policy wording carefully and consider advice from an FCA-authorised insurance provider about whether the cover suits your business.
