What does Seal Security do?
Seal Security is a cybersecurity platform that specializes in fixing open-source vulnerabilities directly in your existing software environment. Instead of requiring teams to upgrade entire libraries or dependencies—which often introduces breaking changes and technical debt—Seal Security provides production-ready, backported patches. These patches address specific CVEs while maintaining compatibility with your current versions, whether you're working with application dependencies, containers, or legacy systems.
The platform stands out by tackling what traditional vulnerability scanners mark as 'unfixable.' It secures transitive dependencies, end-of-life libraries, and even vendor-supplied software where source code access is limited. Seal Security delivers these patches through a unified solution that works across your entire Linux infrastructure, including containers, virtual machines, and bare metal servers, without causing downtime or broken builds.
This tool is particularly valuable for security teams and developers in regulated industries who need to maintain strict compliance standards like FedRAMP, PCI DSS 4.0, or NYDFS. Organizations with legacy systems, complex dependencies, or customer-mandated remediation SLAs benefit from being able to fix vulnerabilities quickly without the risk and effort of full-scale upgrades.
