CISA Names Scott Breor to Lead Infrastructure Security Division as Steve Casapulla Departs for White House Cyber Office

BLUFCISA will likely extend at least 180 tentative job offers by June 30, but three acting appointments across critical divisions signal a bench depth problem that hiring alone cannot resolve.

Steve Casapulla is being detailed to serve as assistant national cyber director for policy at ONCD, Nextgov/FCW and Government Executive reported June 16, citing one current U.S. official, one former official, and a third person familiar with the matter 12. Breor, currently an associate director for CISA security programs, will head the Infrastructure Security Division; Sean Haglund takes ISD's acting deputy director post; and Chip Abernathy moves to the National Risk Management Center as acting assistant director 12. Acting Director Nick Andersen said this week CISA has begun filling 329 mission-critical roles with about 180 tentative job offers expected by end of June, toward a target of roughly 600 hires cited by Secretary Mullin in recent congressional testimony 12.

Analysis
Three acting appointments signal institutional stress at both ends of the federal cyber structure, though Casapulla's move to ONCD may reflect CISA leadership restructuring ISD from within as much as ONCD drawing talent from a depleted agency. The detail fills the policy gap left by Thomas Lind's departure while pulling infrastructure security expertise toward an office already losing staff to morale decline. CISA will likely issue at least 180 tentative job offers for mission-critical roles by June 30, per narrow-corroborated federal trade reporting. Moderate confidence reflects agency control over offer timing, offset by candidate pipeline stress from prior-year attrition. Warner's SSCI data demand elevates this workforce degradation to congressional intelligence oversight; confirmed offers by June 30 make the 600-hire target operationally credible and defer emergency hiring authority requests.
