As recent high-profile losses have demonstrated, cyber insurance is no longer a niche product purchased by a narrow subset of technology organisations. It is now a central pillar of any modern enterprise’s defence strategy against the risks of data breaches, malware and ransomware attacks, and system failures. While early cyber policies primarily provided coverage regulatory costs and liabilities arising from data breaches, products have evolved to provide extensive coverage for first party losses, including business interruption, arising from a wide range of cyber incidents.

Our specialist cyber insurance lawyers have been involved in cyber coverage for over fifteen years and have substantial experience advising policyholders on high‑value, complex and cyber‑related claims.
