Law firm Clyde & Co and risk analytics platform Corax have collaborated to bring you a joint white paper identifying the key drivers of frequency and cost for cyber insurance claims. This paper moves beyond major breaches to examine the day to day breaches that most businesses are experiencing. Unlike other breach reports, this paper tracks each invoiced cost or loss amount associated with a covered breach event. Anonymized data was sourced from 321 data breach events where Clyde & Co acted as monitoring counsel for cyber insurer clients. The breach events were reported to insurers between 2014 and 2015. Files were selected randomly.
