Assaf Keren named Chief Information Security Officer at Meta

Meta named Assaf Keren its next Chief Information Security Officer, succeeding Guy Rosen, who announced earlier in 2026 that he would leave the company after roughly thirteen years. Keren is a veteran enterprise security executive who previously led security at PayPal and Qualtrics, per the appointment coverage.

The succession is notable on two axes. First, Meta replaced a long-tenured insider with an external hire whose background is payments and enterprise SaaS security rather than consumer platform integrity — a signal that the role is being scoped around enterprise-grade security engineering as Meta's AI infrastructure spend accelerates. Second, the transition was announced with a public hand-off period rather than an abrupt exit, which is the pattern boards increasingly prefer for security leadership changes at disclosure-sensitive companies.

According to SecurityWeek, Assaf Keren announced on Wednesday that he is the new Chief Information Security Officer of Meta. The announcement says he replaces Guy Rosen, who announced in June that he would leave the company after 13 years. It says Rosen was Meta's first CISO, appointed in 2022 after leading product security and integrity efforts.

The announcement says Keren most recently served as SVP and Chief Security Officer at enterprise software maker Qualtrics. Before that he spent nine years at PayPal, where, according to the announcement, he held a wide range of leadership roles, including CISO.

The announcement said Rosen had not said, at the time of the announcement, whether he planned to join another company, and that he had indicated he would serve as an advisor. The announcement does not describe the scope of Keren's responsibilities beyond the CISO title.
