Does Professional Liability Cover Data Breaches?

A data incident can create distinct losses: your own investigation and recovery expense, a client’s claim, regulatory response, or business interruption. The NAIC guide separates first-party cyber costs from third-party liability claims, and the sample Hiscox E&O form excludes certain failures to protect personal information. A technology E&O quote may include a security or privacy extension, but check that insurer’s wording rather than relying on the label. Compare the cyber and E&O grants, security-failure definitions, vendor and cloud-provider coverage, privacy liability, breach-response services, waiting periods, sublimits, and coordination clauses. Ask whether accidental disclosure during professional services is covered under E&O, cyber, both, or neither.

A breach may involve a cloud host, vendor, or subcontractor rather than your own network. Ask each insurer how those providers, incident response, and customer claims are treated in the issued forms.
