Cloud security startup Upwind Security Inc has raised $250 million in Series B funding, SiliconANGLE reported on Jan. 27 local time.

The investment was led by Bessemer, with participation from Salesforce Ventures and Picture Capital. Upwind said revenue increased more than 900 percent from a year earlier but did not disclose specific figures.

Upwind provides a security platform that uses eBPF (Extended Berkeley Packet Filter) technology to detect malicious activity in cloud environments. eBPF is part of the Linux kernel and supports collecting more precise security data by turning an operating system into a monitoring tool. If a breach occurs, the platform generates a timeline explaining the start and scope of the incident and identifies tactics used by hackers to propose countermeasures, the company said.

The Upwind platform detects potential vulnerabilities as well as real-time cyber attacks. It links with CI/CD systems to identify software security flaws before deployment and detects regulatory violations that can arise from infrastructure code and configuration changes. It also provides a function that analyzes connections with external services to block unauthorized AI agent access.

Upwind plans to use the funding to expand functions to help developers more easily detect vulnerabilities before deployment.
