TL;DRMeta hired Assaf Keren as its new CISO from Qualtrics and PayPal, replacing Guy Rosen who announced his departure in June
Meta has hired Assaf Keren as its next chief information security officer, filling a vacancy created when Guy Rosen announced his departure in June after 13 years at the company. Keren joins this week from software platform Qualtrics, where he spent two years as chief security officer, and previously held the same title at PayPal. Rosen will remain as CISO through a transition period of several months before leaving later this year, according to Bloomberg, which first reported the appointment.
Keren said in a LinkedIn post on Wednesday that he would focus on building security and trust into Meta’s artificial intelligence systems and underlying infrastructure. The mandate reflects how thoroughly AI has reshaped Meta’s operations since Mark Zuckerberg told employees earlier this year that the company was redirecting capital from headcount to AI infrastructure. Meta has committed up to $145 billion in capital expenditure for 2026, nearly all of it flowing to data centres, GPUs, and the systems supporting its Llama models and Superintelligence Labs.
The CISO role carries particular weight at Meta after a turbulent year for the company’s security posture. In June, hackers exploited a vulnerability in Meta’s AI-powered customer support chatbot to hijack more than 20,000 Instagram accounts, including high-profile pages linked to public figures and government organisations. Attackers tricked the chatbot into changing account recovery email addresses, allowing them to reset passwords and seize control before Meta patched the flaw.
