White House nominates Palantir’s LoSapio to lead Homeland Security’s cyber agency

WASHINGTON, Nov 9 (Reuters) – The White House said on Monday it has nominated Michael LoSapio to be the director of the US Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency.

• LoSapio will take over from acting CISA Director Nick Andersen

• The agency has been without a Senate-confirmed leader for almost 22 months, even as AI-driven cyber threats increasingly strain defenders in and out of government

• CISA, which is responsible for defending civilian networks from hackers and spies, has seen its staffing fall by about a third since Trump took power in 2025

• LoSapio’s nomination comes after three large-scale breaches — at DHS, the FBI and the Pentagon — were disclosed in the past three months

• LoSapio, chief information security officer at Palantir Technologies, did not immediately respond to requests for comment
