Israeli cloud security company Upwind has raised approximately $300 million at a valuation of $3.8 billion, more than doubling its valuation in less than eight months.

The new round, led by Bessemer Venture Partners and TCV, brings Upwind’s total funding to more than $700 million, according to Calcalist. Craft Ventures, Salesforce Ventures, Greylock, Cyberstarts, Leaders Fund and Alta Park Capital also participated.

The latest financing follows Upwind’s $250 million Series B in January, which valued the company at approximately $1.5 billion. Calcalist reported that Salesforce Ventures subsequently invested tens of millions of dollars at a $1.6 billion valuation.

In a post announcing the financing, Upwind founder and CEO Amiram Shachar described the latest round as a major milestone, calling Upwind “the first unicorn in modern cloud security” and “one of the most capitalized companies in the world focused on solving the cloud security problem for the next, at least, 20 years.”

“We were not trying to incrementally improve cloud security. We were responding to a real shift in reality,” Shachar wrote.

Cloud infrastructure was becoming more complex, data volumes were exploding and AI was accelerating both innovation and risk, while many security models were still designed for a much simpler environment.

“That belief has shaped every decision we have made at Upwind,” Shachar wrote, describing an approach built for continuous change and real-world complexity rather than static security assumptions.

Upwind was founded in 2022 by Shachar and former Spot.io colleagues Liran Polak, Lavi Ferdman and Tal Zuri. The company develops cloud security software that monitors live environments rather than relying primarily on static scans. Its “runtime-first” approach helps security teams distinguish vulnerabilities that pose an actual risk from those that exist only on paper, according to Calcalist.

Shachar said the new funding will allow the company to “scale our speed” by investing further in its platform, supporting more customers and expanding across “AI, data, code, and whatever comes next.”

“We are focused on helping security teams operate with confidence in a world that does not slow down,” he wrote. “This Series B is fuel. And we are just getting started.”
