Jen Easterly, director of the U.S. Cybersecurity and Infrastructure Security Agency (CISA), will depart the agency on January 20.
Easterly and deputy director Nitin Natarajan will both leave CISA as the new Trump administration begins.
During Easterly's tenure, CISA pioneered new initiatives to secure devices and technologies, defended against cyber threats, and supported the Ukrainian government in 2022.
The Trump administration's transition team has not yet announced a successor for the directorship of CISA.
