After less than two years as chair of Dilworth Paxson’s health care group, partner Katherine M. Keefe has left the firm to head up the new business unit of network security and privacy risk insurer Beazley.

The new unit, called BBR Services, is responsible for carrying out the services provided to policyholders covered under Beazley Breach Response, which launched in 2010 and which Beazley describes as “a unique insurance, loss control and risk mitigation service that provides a comprehensive service to notify and protect the customers of policyholders that have suffered a data breach.”
