Joseph T Petro

Petro spent 23 years in the Secret Service, including four years protecting President Ronald Reagan. Sandy Weill, the then-head of what would become Citigroup, hired him in 1993 to oversee fraud prevention, investigations and security for the company. During his 20 years at the bank, Petro dealt with security issues around the world and coordinated Citigroup's response to the 9/11 attacks. In recent years he has overseen the bank's efforts to combat rising cyber-crime and hacker attacks.
