About
Seal Security is a Tel Aviv, Israel-based open source vulnerability patching platform — backed by Y Combinator (W20) with $20 million in total funding from MORE Investment House, SBI Insurance Group, Crew Capital, Cyber Club London, and PayPal Alumni Fund — providing development and security teams with standalone, production-ready security patches for open source software vulnerabilities that fix critical CVEs without requiring version upgrades or introducing breaking changes to application dependencies, Linux systems, and container-based images.
