The White House nominates Michael LoSapio to lead the cybersecurity agency

On Monday, the White House nominated Michael LoSapio to serve as director of the Cybersecurity and Infrastructure Security Agency (CISA), an agency within the United States Department of Homeland Security (DHS). The nomination comes as cyber threats, including those powered by artificial intelligence, intensify, while the agency has gone nearly 22 months without a Senate-confirmed director.

LoSapio currently serves as chief information security officer at Palantir Technologies. If confirmed, he will replace Nick Andersen, the agency’s current acting director.

CISA is responsible for protecting U.S. civilian networks from cyberattacks and espionage operations. The agency has lost approximately one-third of its employees since Donald Trump returned to the White House in January 2025.

The nomination was announced after three major security breaches targeting the Department of Homeland Security, the FBI and the Pentagon were disclosed over the past three months. Michael LoSapio must receive Senate approval to officially take over leadership of CISA.
