SAN FRANCISCO: Twitter shook up the top ranks of its security team this week with the termination of the head of security and the exit of the chief information security officer (CISO), the company told employees on Wednesday, as its new CEO Parag Agrawal reorganises the social media service.
Peiter Zatko, the head of security, is no longer at the company, Twitter confirmed. CISO Rinki Sethi will depart in the coming weeks.
The changes follow “an assessment of how the organisation was being led and the impact on top priority work,” according to a memo from Agrawal that was sent to employees on Wednesday and obtained by the NYT. Agrawal said the “nature of this situation” limited what he was allowed to share with employees. Sethi and Zatko did not immediately respond to requests for comment.
Agrawal, who was appointed Twitter’s CEO in November, has shuffled the company’s executives since taking over from Jack Dorsey, a founder. In December, Agrawal reorganised the leadership team and dismissed Dantley Davis, the chief design officer, and Michael Montano, the head of engineering. Zatko and Sethi joined Twitter in late 2020. Sethi was previously a VP of information security at IBM and had worked in security at Intuit and Walmart.
