Chris Krebs, the inaugural Director of the Cybersecurity and Infrastructure Security Agency (CISA), has resigned from his executive role at SentinelOne. This decision follows an executive order from President Donald Trump that revoked Krebs' security clearance and initiated a Department of Justice (DOJ) investigation into his tenure at CISA.​

Background: A History of Conflict

Krebs, appointed by Trump in 2018, led CISA until November 2020, when he was dismissed after publicly refuting claims of widespread election fraud in the 2020 presidential election. His stance positioned him as a prominent critic of Trump's post-election assertions.​‍

In April 2025, President Trump signed an executive order that not only revoked Krebs' security clearance but also suspended clearances for employees at entities associated with him, including SentinelOne. The order mandates a comprehensive review of CISA's activities during Krebs' leadership, focusing on potential misconduct or unauthorized dissemination of classified information. ​

Resignation and Personal Statement

In an email to SentinelOne staff, Krebs stated:

"This is my decision, and mine alone. This is my fight, not the company's. 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." ​

Krebs emphasized that his resignation is intended to allow him to focus entirely on addressing the DOJ investigation and the broader implications of the executive order.​

Industry Response and Implications

SentinelOne, a cybersecurity firm with a market capitalization of approximately $5.6 billion, acknowledged Krebs' departure but indicated that the revocation of security clearances is not expected to materially impact its operations. ​

Despite the significance of the executive order, the cybersecurity industry has largely remained silent. Out of 36 organizations contacted, only one publicly commented on the situation, highlighting a reluctance to engage in political disputes. ​‍

Broader Context: A Pattern of Retaliation

The actions against Krebs are part of a broader pattern of retribution by President Trump against former officials who have criticized him. Similar measures have been taken against other individuals, including Miles Taylor, a former Department of Homeland Security official. ​‍

Looking Ahead

Krebs' resignation underscores the tensions between the current administration and former officials who have opposed its narratives. As the DOJ investigation proceeds, the cybersecurity community and the public will be watching closely to see how these developments unfold and what implications they may have for the industry's relationship with government entities.
