Chris Krebs leaves SentinelOne after Trump memo, saying ‘this is my fight’

Former CISA Director Chris Krebs resigned from his senior role at SentinelOne to focus on challenging the Trump administration’s April 9 memo revoking his security clearance and initiating a broad probe into his and CISA’s conduct related to the 2020 election. Krebs characterized the action as punitive and an attack on dissent, noting it requires his full attention and framing it as a fight for democracy, free speech, and the rule of law, while major cybersecurity firms have largely remained quiet about the move.
