Seal Security

Seal Security sells an AppSec remediation agent that fixes vulnerabilities in open source software without forcing upgrades. Instead of only alerting on a known CVE, it supplies a sealed version of the affected library: the exact version a team already runs plus a backported security patch. This matters most when the upstream project has reached end of life or when moving to a newer major version would mean a risky migration. The product covers application dependencies, both direct and transitive, as well as operating system packages and container images, with a catalog of more than 2,000 images with full version history. Patching rules can be applied across all projects at once, and the service integrates with existing scanners, software composition analysis tools and CI workflows. The vendor states a 72 hour SLA for critical and high severity CVEs, and provides provenance, traceability and reporting aimed at audits such as FedRAMP, PCI DSS 4.0 and NYDFS 500. It is aimed at security and engineering teams, from startups to enterprises, that need to clear vulnerability backlogs without disrupting developers. Pricing is not published as amounts. Every plan includes 5 free patches, and the tiers are Starter (a defined pilot scope), Business (ongoing remediation for selected apps and environments) and Scale (unlimited coverage for enterprise standardization). Quotes depend on scope, supported ecosystems, deployment requirements and support level, and are obtained by contacting the vendor.
