Cybersecurity firm Upwind Security announced a $400 million Series C funding round at a $3.8 billion valuation, just nine months after its previous $250 million round.

The San Francisco-based company, founded in 2022 by Amiram Shachar (who previously founded Spot.io, acquired by NetApp for $450 million), offers a runtime-native cloud security platform used by hundreds of organizations including Siemens, Roku, and Nubank.

Platform Capabilities

Upwind's platform "uses runtime intelligence to help security, development, and DevOps teams identify their most critical exposures, remediate risks proactively, and detect attacks in real time." The company provides increased visibility into networks, APIs, and data flows.

Investment Details

The latest funding round was led by Bessemer Venture Partners, with participation from Canapi Ventures and existing investors including TCV, Greylock Partners, and Salesforce Ventures. This brings Upwind's total funding to over $800 million.

The massive funding round comes just days after reports emerged that Upwind had attracted acquisition interest from several companies, including Datadog.
