‘This is my decision, and mine alone,’ Chris Krebs said Wednesday.
Chris Krebs, the man at the center of President Donald Trump’s revoking of security clearances held by SentinelOne, has left his role at the security vendor.
In an email sent by Krebs to all employees of Mountain View, Calif.-based SentinelOne and reviewed by CRN, he said that “with a heavy heart,” he is “stepping away from SentinelOne, effective immediately.”
“I want to be clear: this is my decision, and mine alone,” Krebs wrote in the email, dated Wednesday afternoon. “This is my fight, not the company’s. … 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.”

Trump Takes On SentinelOne
CRN has reached out to SentinelOne, Krebs, The White House and the U.S. Cybersecurity and Infrastructure Security Agency (CISA) for additional comment.
SentinelOne has about 5,000 channel partners worldwide, according to CRN’s 2025 Channel Chiefs.
Krebs’ account on the LinkedIn social media network shows that he has left his position as chief intelligence and public policy officer at SentinelOne and as president of the PinnacleOne Strategic Advisory Group.
End dates for both positions are listed as April 2025. He started both jobs in November 2023 but served as a SentinelOne advisory board member dating back to June 2021.
On April 9, Trump signed a memo that revokes any active security clearances held by Krebs, the former director of the CISA, and suspends any security clearances held by individuals connected with SentinelOne.
The memo also directs the U.S. attorney general and the homeland security secretary to investigate Krebs’ activities during his time as a government employee, which included serving as the first director of CISA from its formation in November 2018 under the first Trump presidency until November 2020.
In an email to SentinelOne employees by Tomer Weingarten dated for one minute after Krebs’ email, the company’s CEO and co-founder thanked Krebs “for his transparency and integrity–especially in this difficult moment.”
“His leadership made a lasting impact on SentinelOne, PinnacleOne, and the broader cybersecurity community,” Weingarten said. “He helped shape important conversations and strengthened public-private collaboration. The work he led–especially in service of democratic institutions and critical infrastructure–is foundational and will continue to shape our impact moving forward.”
The CEO continued by saying Krebs will “take on this next chapter with the same clarity, conviction, and humility that defined his time here, and he carries our full respect with him as his journey continues.”
Weingarten said that SentinelOne continues to support the U.S. and global allies against nation-state and cybercrime adversaries. “Our team remains unwavering in our commitment to be a force for good–in this industry and in the world,” he said.
SentinelOne previously said that fewer than 10 people at the company have held such clearances, and says it expects the move will not “materially impact our business in any way.”
In Krebs’ email, he thanked SentinelOne and said what the company is “building is truly unparalleled in this industry” and “redefining what’s possible in cybersecurity.”
