Trump wants to take a battle axe to CISA again and slash $707M from budget

Ex-CISA official tells The Reg: ‘this would weaken the system for managing cyber risk’

The US Cybersecurity and Infrastructure Security Agency’s budget will see yet another deep cut if Congress approves President Trump’s proposal to slash CISA’s spending by $707 million in fiscal year 2027.

America’s lead cyber-defense agency already lost millions in funding and about a third of its workforce (close to 1,000 people) during the first year of Trump’s second term. According to the president’s proposed budget [PDF], the spending plan “refocuses CISA on its core mission.”

Trump’s fiscal 2026 budget wanted to chop about $491 million from CISA’s spending, although Congress ultimately approved a reduction of about $135 million [PDF].
