SentinelOne plans to eliminate approximately 240 employees as the company-wide rollout of its Frontier Artificial Intelligence model will lead to significant productivity gains across the organization.

The Silicon Valley-based endpoint security vendor last week announced plans to cut its 3,000-person staff by about 8%, or about 240 positions. Work that once took months can now be completed in weeks or even days. CEO Tomer Weingarten said the headcount reductions will strengthen SentinelOne’s go-to-market reach and help improve productivity across the sales organization.
Weingarten told investors on May 28 that “we have more organizational capabilities than we think we need at this stage of our size and growth.” “Also, the way we hire is changing. The people we’re hiring are different and much of what we’re doing is just in line with our success in the luxury market in emerging product categories.”
Chief Financial Officer Sonali Parekh said the layoffs will allow Sentinel One to achieve annual cost savings of $45 million once fully implemented. Sentinel One expects to spend $12 million to $14 million on severance and employee benefits, and an additional $10 million to $12 million on stock compensation for departing employees, according to SEC filings.
Where SentinelOne recognizes opportunities to reduce cost-to-market
Sentinel One stock has fallen $1.34, or 7.4%, to $16.68 per share since the layoff announcement. The company is valued at $5.6 billion, just 3% of endpoint security rival CrowdStrike’s $182.1 billion valuation. This is SentinelOne’s first major layoff since June 2023, when the company cut 105 employees, or 5% of its workforce, following a significant drop in data usage for its consumption-based pricing products (see below). SentinelOne lays off 5% of staff due to declining data consumption).
Weingarten said on May 28: “It’s not an easy decision, but at the same time we want to approach these areas in the most aggressive way possible. We recognize the opportunity now and want to put all our resources in the right places. This has had little impact on our technology group. We are giving the market what it needs.”
On the go-to-market front, Weingarten said he sees an opportunity for SentinelOne to level up its team, streamline distribution and drive increased operating leverage, sales efficiency and execution speed. Weingarten said the headcount reductions will give SentinelOne the resources and flexibility to focus its investments on its highest-conviction growth areas: AI, data, cloud and endpoint.
“We do not anticipate any disruption to market launch,” Weingarten said. “As you can probably imagine, this is due to natural performance management, people who weren’t the biggest contributors. We’re focusing on where we see the biggest contributions. So if anything, this will put more emphasis on distilled and crystallized go-to-market movements. I don’t expect big changes.”
Weingarten said SentinelOne will invest the proceeds from the headcount reductions into using frontier AI models to provide the best cutting-edge protection to its customers. Weingarten said that a few years ago, much of SentinelOne’s innovation came from other companies through acquisitions, but now SentinelOne wants to build and drive organically.
“With the power of our research and development and the power of our talent, we want to do even more,” Weingarten said. “We want to empower them to do more. We want to bring more talent on board. And that’s how we’re thinking about the philosophy behind reinvestment.”
Where SentinelOne plans to invest proceeds from headcount reductions
Mr. Parekh said the headcount reductions will provide Sentinel One with the financial flexibility to intentionally reinvest in key growth areas while driving significant operating margin expansion. He said SentinelOne is leveraging productivity gains to become more agile and investing in solutions such as AI security, purple AI, data and cloud, which Parekh believes are key to achieving sustainable growth.
“With our strong growth profile, clear technology leadership and increasing structural tailwinds, we have all the ingredients to expand into a highly profitable and durable multi-billion dollar business,” Parekh told investors.
Despite the layoffs, SentinelOne’s workforce has increased by 300 people (11.1%) since April 2025 and 600 people (25%) since April 2024.
“We are focused on driving efficiency improvements and allocating resources to these key growth areas, which naturally means AI, data, cloud, and endpoint,” Weingarten said. “These are growth areas for us. This is our main focus. And this is absolutely the right thing for the business.”
Several security vendors have announced layoffs in recent weeks to address both productivity gains and increased token costs associated with cutting-edge AI models such as Anthropic’s Claude Mythos Preview. In May, Cloudflare cut more than 1,100 jobs from its 5,483 staff to align operations with AI-driven workflows and increase productivity as internal AI usage increased by more than 600%.
Also in May, security operations firm Arctic Wolf laid off 250 of its estimated staff of 3,402 to free up resources to invest in its superintelligence platform and agent-based SOC products. In May, Cisco announced plans to lay off 4,000 people, nearly 5% of its workforce, to shift investment to high-demand areas such as silicon, optics, security and AI.
