Upwind raises about $300m at a $3.8bn valuation to scale cloud security
The runtime-first platform will expand as enterprises seek protection across cloud workloads, identities and active threats.
Security built around live cloud activity
Upwind’s cloud security platform combines configuration analysis with live telemetry from cloud and container environments. It maps identity permissions, prioritizes vulnerabilities that attackers can exploit and helps security teams detect and isolate active threats across infrastructure.
The company raised approximately $300 million at a reported $3.8 billion valuation, with proceeds to scale the platform and add customers. Upwind’s product spans posture management, workload protection, detection, response and identity security. This is separate from its $250 million Series B announced in January 2026, which remains an earlier financing.
