Seal Security is a rapidly growing cybersecurity startup. We help customers save developer hours and headaches while reducing both software supply-chain risk and organizational friction- by making the process of remediating open-source vulnerabilities easier and more efficient with fully-compatible, security-patched versions of the libraries our customers are using. We are backed by top-tier venture capital firms, guided by industry-leading cybersecurity and go-to-market experts, and have exploded out of stealth mode with numerous Fortune 500 customers.

Seal Security is redefining open source vulnerability remediation by providing standalone security patches that ensure seamless and predictable fixes for vulnerabilities in both application code and images. By backporting security fixes and creating fully compatible versions of open source packages, Seal enables security teams to apply patches independently of R&D involvement. This approach decouples security fixes from feature upgrades, centralizes the replacement of all vulnerable package instances across all CI pipelines, and automates and scales the vulnerability remediation processes.

Backed by top-tier venture capital firms, Seal Security is a well-funded and fast-growing company guided by industry-leading cybersecurity and go-to-market experts. We have rapidly grown out of stealth mode with numerous Fortune 500 customers and are expanding our team to continue scaling our impact.
