CISA entered 2026 with a smaller budget and staffing, creating immediate concerns about federal cyber capacity as it faced fewer resources amid a tougher threat environment. According to CSIS, cyber operations are likely to shape the U.S.-Israel conflict with Iran, with a sharp rise in attacks linked to the broader war and notable activity in March 2026.
DHS’s FY2026 budget documents show CISA with $2.4 billion, 2,649 positions, and 2,324 full‑time staff roles, compared with $3.0 billion, 4,021 positions, and 3,641 staff in FY2025. The 2026 proposal also targeted cuts including 14 election‑security positions and about $40 million in funding, around $45 million for Cyber Defense Education and Training, and 35 positions plus $70 million from the National Risk Management Center.
By January 2026, CISA reportedly faced at least 998 departures since the administration took office, with broader losses of around 1,000 personnel noted by June 2025. The article stresses that the impact extends beyond a single budget line, widening the gap between a growing threat environment and civilian cyber backstop. It also notes Iran‑linked activity, including the Handala Hack Team’s alleged breach of a high‑profile email and a March 2026 spike to nearly 5,800 attacks from almost 50 Iran‑tied groups.
