List of Fortune 500 Chief Information Security Officers

Third Annual Edition of the CISO 500. 

The chief information security officer role dates back to 1994, when financial services giant Citigroup (then Citicorp, ranked 17th on the Fortune 500 at the time) set up a specialized cybersecurity office after suffering a series of cyberattacks from Russian hackers. Now, a quarter-century after the first CISO emerged, every one of our nation’s biggest businesses has a cybersecurity leader. Scroll down the list to see who’s who.
