Illegitimi non carborundum? Nice password, Mr Ex-CISA

Chris Krebs, the former head of the US Cybersecurity and Infrastructure Security Agency (CISA) and a longtime Trump target, has resigned from SentinelOne following a recent executive order that targeted him and revoked the security clearances of everybody at the company.

Krebs, a Republican who Trump appointed to lead US cybersecurity operations in 2017, was famously fired via tweet five years ago after he publicly contradicted Trump's false claims of election fraud. Krebs declared the 2020 US presidential election "the most secure in American history."

Krebs joined SentinelOne as Chief Intelligence and Public Policy Officer in November 2023 after the security shop snapped up his consultancy, Krebs Stamos Group.

Last week, Trump issued a memorandum revoking security clearances for Krebs and any entities associated with him, including SentinelOne. The order also directed the Attorney General and the Department of Homeland Security to investigate Krebs' activities during his tenure at CISA, including his assurances of 2020 election security.

"For those who know me, you know I don't shy away from tough fights," Krebs said in an email sent to company employees and shared on Wednesday in a LinkedIn post:

But I also know this is one I need to take on fully — outside of SentinelOne. This will require my complete focus and energy. It's a fight for democracy, for freedom of speech, and for the rule of law. I'm prepared to give it everything I've got.
