Seal Security, an Israeli open source security startup, has raised $13 million in a Series A round led by Vertex Israel, bringing its total funding to $20 million. Founded in 2022, the company uses generative AI to automate vulnerability detection and remediation in open source software, offering production-ready patches without requiring version upgrades. The new funds will support platform development and go-to-market efforts as Seal continues to streamline security for DevOps and IT teams.
