Resignations of Key Officials
The Cybersecurity and Infrastructure Security Agency (CISA), a critical component of the U.S. Department of Homeland Security, is undergoing significant transitions. The recent resignations of two senior officials, Bob Lord and Lauren Zabierek, have drawn attention to the agency’s challenges, including planned workforce reductions and a stalled leadership nomination. This article explores these developments, their implications for CISA’s mission, and the broader context of cybersecurity in the U.S.
On April 21, 2025, Bob Lord and Lauren Zabierek announced their departures from CISA via LinkedIn posts. Lord, who joined CISA as a senior technical advisor in 2022, brought extensive experience from roles at the Democratic National Committee, Twitter, and Yahoo (CISA Announcement). Zabierek, a senior advisor, previously served as Executive Director of the Cyber Project at Harvard’s Belfer Center and has a background in intelligence and cybersecurity (Belfer Center). Their resignations mark a significant loss of expertise for CISA.
Workforce Reductions at CISA
The resignations occur against a backdrop of substantial workforce challenges. Reports indicate that CISA could face cuts affecting up to 1,300 employees, approximately half of its full-time staff, and 40% of its contractors under the Trump administration (Nextgov/FCW). This follows an earlier attempt to terminate 130 probationary staffers, which was initially blocked by courts but later overturned on appeal. The Department of Homeland Security has also offered buyouts to employees, with a decision deadline of April 14, 2025 (Reuters).

| Potential Staff Cuts | Up to 1,300 employees (50% of full-time staff) and 40% of contractors |
| Previous Attempt | 130 probationary staff cuts, blocked in court, overturned on appeal |
| Buyout Offer | Offered by DHS, deadline April 14, 2025 |

These reductions have sparked concerns about a potential “brain drain” at CISA, with critics warning that the loss of experienced personnel could weaken the nation’s cybersecurity posture (POLITICO).
Contributions to Secure by Design
Both Lord and Zabierek were key contributors to CISA’s Secure by Design initiative, which aims to enhance the security of technology products by holding manufacturers accountable for design flaws (WashingtonExec). The initiative encourages software developers to integrate security measures early in the product lifecycle, reducing exploitable vulnerabilities. Their work has been praised for advancing CISA’s mission to protect critical infrastructure.
CISA’s Ongoing Commitment
CISA Executive Director Bridget Bean has reaffirmed the agency’s dedication to cybersecurity despite the personnel changes. In a statement, Bean expressed gratitude for Lord and Zabierek’s foundational contributions and emphasized that CISA remains focused on strengthening national cyber defenses (The Record).
Leadership Transition Challenges
The resignations coincide with uncertainty over CISA’s leadership. President Trump nominated Sean Plankey, a former cybersecurity official at the Department of Energy and National Security Council, to serve as CISA’s director (Axios). However, Senator Ron Wyden has placed a hold on Plankey’s confirmation, demanding the release of an unclassified 2022 report on security vulnerabilities in U.S. telecommunication networks (Cybersecurity Dive). Wyden’s concerns are linked to the Salt Typhoon hacking campaign, which highlighted telecom security weaknesses.

| Nominated By | President Donald Trump |
| Status | On hold by Sen. Ron Wyden |

Broader Implications
The combination of leadership changes and workforce reductions raises questions about CISA’s ability to address growing cyber threats. The agency plays a critical role in protecting civilian government networks and election infrastructure, areas that have faced scrutiny and require robust expertise. The Secure by Design initiative, in particular, relies on experienced leadership to drive industry accountability.
Conclusion
The resignations of Bob Lord and Lauren Zabierek, coupled with planned staff cuts and a delayed leadership transition, present significant challenges for CISA. While the agency remains committed to its cybersecurity mission, the loss of key personnel and potential reductions could impact its effectiveness. As CISA navigates these changes, the focus on initiatives like Secure by Design and the resolution of leadership uncertainties will be crucial for maintaining national cyber resilience.
