Jen Easterly, director of the Cybersecurity and Infrastructure Security Agency (CISA), plans to step down on January 20, 2025, coinciding with President-elect Donald Trump’s inauguration, according to sources familiar with her decision. Forbes correspondent Emil Sayegh declares this departure marks “the end of a transformative era in U.S. cybersecurity.” As confirmed in internal emails and an all-hands meeting, Deputy Director Nitin Natarajan is also expected to leave.
Traversing a tumultuous period for cybersecurity, Easterly’s tenure has naturally been marked by a series of high-stakes challenges and significant achievements. She led CISA during major cyberattacks on U.S. government systems, including a Chinese-led hack that compromised senior officials’ email accounts. Throughout national election cycles, she was a steadying voice, affirming the integrity of election infrastructure during the 2024 presidential election.
Easterly’s expertise extended to the private sector, where she was Morgan Stanley’s global head of cybersecurity before taking on the top role at CISA in 2021. Her confirmation followed an eight-month leadership void after Trump fired CISA’s first director, Chris Krebs, for declaring the 2020 election secure.
A staunch advocate for proactive cybersecurity, Easterly championed the Secure by Design initiative, urging private-sector manufacturers to implement default security standards in their products. Under her guidance, CISA also provided critical guidance on emerging technologies, including AI and quantum information sciences, helping organizations prepare for the transition to quantum-resilient cryptography.
Under her tenure, CISA has explored the dual role of AI in cybersecurity—both as a tool for defenders and a weapon for attackers. Although AI can revolutionize threat detection and response, adversaries can also leverage it to scale phishing campaigns, automate attacks, and bypass traditional defenses.
Perhaps even more forward-looking is her focus on quantum computing and its implications for cryptography. Quantum computers, when fully realized, will have the power to break widely used encryption methods, potentially compromising critical infrastructure and sensitive data globally. CISA, under Easterly’s leadership, pushed for a national transition to quantum-resilient cryptography. This involved publishing detailed frameworks, such as their partnership with the National Institute of Standards and Technology (NIST) to develop cryptographic algorithms resistant to quantum attacks.
Easterly’s departure, although aligned with standard presidential transitions, raises questions about CISA’s trajectory under the incoming administration. GOP-led criticisms of the agency’s alleged role in censorship, which Easterly has denied, recently influenced a Supreme Court case that ruled in favor of the Biden administration. These allegations, championed by figures like Sen. Rand Paul, could affect the agency’s operations moving forward. Paul, next in line to chair the Senate Homeland Security Committee, has previously blocked funding for CISA programs, including chemical security screenings.
Further concerns stem from Trump’s proposed budget cuts, which some fear could compromise government cybersecurity initiatives. Politico reported that Ohio Secretary of State Frank LaRose is being considered as Easterly’s successor, a choice that reflects uncertainty about how CISA will navigate the political and operational shifts ahead.
