Supply chain protection provider Socket has announced raising $60 million in a Series C funding round that brings the total raised by the company to $125 million and its valuation to $1 billion.

The new investment round was led by Thrive Capital, with additional support from Andreessen Horowitz, Abstract Ventures, and Capital One Ventures.

Founded in 2020, California-based Socket has built a platform that analyzes open source dependencies to identify malicious behavior before affecting enterprise products.

The platform relies on AI-assisted analysis, combined with human verification, to detect potential supply chain compromises, prioritize vulnerability patching based on confirmed exploitation, and address dependency risks.

The new funding will allow Socket to improve its recently released Socket Firewall, designed to block malicious packages before they can reach developer environments or CI pipelines, and to expand its certified patches, which fix exploited vulnerabilities.
