SentinelOne is a US cyber-security company, founded in 2013 by the Israelis Tomer Weingarten and Almog Cohen, that sells an "autonomous" platform for detecting and blocking threats on computers and servers. It priced its initial public offering on the New York Stock Exchange on 30 June 2021 at $35 a share for 35 million shares.[1] CNBC called it the "highest-valued cybersecurity IPO ever"; the shares closed their first day up 21 per cent, giving a market value of more than $10 billion.[2]
Founders and the IDF
SentinelOne's founders served in the Israel Defense Forces, but have stressed that they were outsiders to the Unit 8200 network. In a 2021 interview Calcalist wrote that Weingarten and Cohen "were not the typical Israeli tech founders, not former soldiers in an elite technology military unit". Asked about his military service, Weingarten said he had wanted to join the IDF's computing corps, MAMRAM, "but somehow we rolled into all sorts of roles in the military". He added: "We are not anyone's friends, we did not serve anywhere notable in the military and we don’t know people", and "We do not have the 8200’s frame of mind". He said many investors had asked "if I was 8200 or 81, and the answer was no".[3] Cohen left the company about three years after it was founded.[3]
Acquisitions
In August 2025 Ctech reported that SentinelOne was buying Prompt Security, a generative-AI security start-up whose founders were "both graduates of Israel's elite 8200 Unit", for about $250 million.[4]
