Trump nominates Palantir CISO LoSapio to serve as next CISA director

LoSapio joined Palantir for the second time in 2017 to serve the company’s infrastructure and network security group lead. He has served as the company’s chief information security officer for two years and previously worked at the company for nearly three years as a system engineer. LoSapio was included in a list of nominations sent to the Senate on Nov.

9. CISA has been operating without a Senate-confirmed director since Jen Easterly stepped down at the start of the second Trump administration. Trump nominated Sean Plankey in March 2024 to serve as CISA director but Plankey withdrew in April, recognizing that he would not be confirmed by the Senate amid unrelated concerns over activities at the Department of Homeland Security.

Without a Senate-confirmed leader, Nick Andersen has been leading the agency for the past eight months as CISA deputy director and acting director. Andersen was appointed in September 2025 to serve as CISA’s executive assistant director for cybersecurity but was elevated in February with the departure of Madhu Gottummukkala, who was previously CISA director in an acting capacity. LoSapio comes from an engineering background, starting his career at Seton Hall University and playing similar roles at the Sevens Institute of Technology and New York University.
