Socket, which provides tools to help detect open source code vulnerabilities, raised a $40M Series B led by Abstract Ventures, taking its total funding to $65M

Context & Ripple Effects
Socket's $40M Series B follows its earlier $20M Series A for open-source vulnerability scanning, showing continued investor backing for a company focused on securing widely reused code dependencies.
The round sits in a funding arc that later included a $60M raise at a $1B valuation, indicating that Socket's approach gained further financial support as software-supply-chain security became a sustained category.
First-order effects
- Socket gains $40M in new capital, bringing its reported total funding to $65M and extending its capacity to build and sell tools for detecting open-source code vulnerabilities.
- Abstract Ventures becomes the lead investor in this financing, tying it directly to Socket's next stage of growth.
Second-order effects
- The raise strengthens Socket's ability to compete for customers and security talent against other open-source vulnerability-scanning vendors, including the category represented by Snyk's earlier funding.
- Companies relying on open-source dependencies gain another better-funded specialist supplier, increasing pressure on security teams to treat dependency scanning as a dedicated procurement category.
Third-order effects
- If follow-on financings continue, open-source security is likely to evolve from a point-scanning market toward a more concentrated software-supply-chain defense layer, with capital favoring vendors that can become durable platforms.
- The later funding trajectory suggests investors may increasingly view defenses around shared code ecosystems as infrastructure rather than an optional developer tool, though adoption and vendor consolidation remain uncertain.
The trend: This is one data point in the institutionalization of software-supply-chain security as a core layer of enterprise cyber defense.
