Pulse 2.0 posted that Upwind Security is raising $300 million in new financing at a $3.8 billion valuation. The account attributes the detail to Bloomberg and adds that investors continue directing capital toward cybersecurity companies protecting cloud infrastructure. The post links to a pulse2.com article repeating the same report. The evidence packet contains only this secondary account of the Bloomberg-sourced claim, with no first-party confirmation or additional details from Upwind Security itself.
