Why security and engineering teams trust us

How do you Seal open source vulnerabilities?
- Integrate Seal with your build pipelines, or directly to your artifact server.
- During build, Seal swaps all known vulnerable libraries with their Sealed counterparts, according to the pre-approved organization policy.
- From there, your release process stays the same: build, test, and deploy.
- Finally, Seal helps ensure all projects stay up to date with the latest security patches to prevent drift.
Autonomous remediation. Human-approved.
Always in your control - every fix is visible, reviewable, and approved by your team.
Remediation you can ship with confidence

No upgrade required
Don’t get forced into risky upgrades just to address a CVE in a transitive dependency. Patch now, upgrade on your own timeline.
Fix the “unfixable”
Secure transitive dependencies, EOL libraries, and legacy systems that scanners mark as "no fix available".
Compliance ready, always
Patches are human-readable, so you can review before applying. Stay continuously compliant with 72-hour remediation SLAs.
One command is all it takes
Run a single CLI command after resolving your dependencies - no manifest files touched, no dependency conflicts.

Reviewed by humans, tested by machines, validated by AI
Each patch goes through expert security review, extensive automated testing, and Seal’s AI validation to guarantee build safety.

No vendor lock-in
Sealed libraries remain in your registry indefinitely. Even if you stop using Seal.

Fix open source vulnerabilities across your stack with one unified solution

Secure application dependencies
Patch direct and transitive dependencies in place, even the ones your scanner marks as “unfixable”.
Uphold compliance and meet customer SLAs

Secure end-of-life environments
Keep CentOS, RHEL 6, and other EOL distros secure with post-EOL security patches.

Secure legacy and hard-to-manage code
Fix vulnerabilities in legacy apps and vendor-supplied software, even without source code access.

Secure your entire Linux infrastructure
Deploy backported fixes across containers, VMs, and bare metal without breaking upgrading your OS.
