Uber's CISO on building an insider threat program for AI

Uber runs one of the world's largest real-time marketplaces, with over 40 million trips and delivery orders a day. Philip Martin, Uber's Chief Information Security Officer (CISO), leads the team that protects Uber's data and the riders, drivers, and couriers who use the platform in the real world. His team started working with Claude on threat modeling before Claude Code existed, assembling context by hand.

Martin thinks AI agents need the same kind of insider threat program companies already run for their employees.
