Remediation in the Mythos Era

Mythos broke the old way to fix open source vulnerabilities. Seal built the new one.

Seal delivers production-ready, human-vetted patches that remediate open source vulnerabilities in place, including the "unfixable" ones in transitive dependencies, end-of-life packages and legacy systems. No version upgrades, no migrations, no exception tickets.

Three forces just collided

• The Mythos surge: frontier AI (Claude Mythos) autonomously surfaced more than 6,200 high and critical open source vulnerabilities across 1,000+ projects. Disclosure is now machine-scale.
• The new benchmark: CISA BOD 26-04 requires federal agencies to remediate in as little as 3 days, and it is fast becoming the bar auditors, customers and boards hold everyone to.
• The mandate to fix: the June 2026 AI Executive Order directs a federal clearinghouse to coordinate vulnerability validation, remediation and patch distribution, putting federal weight behind fixing, not just finding.

More vulnerabilities, disclosed faster, against a 3-day bar the whole industry now measures against. Legacy scanners still answer with an upgrade you cannot take. Finding is no longer the hard part. Fixing is.

How Seal fixes what scanners can't

• No upgrade required: Seal backports the fix into a sealed version of the package you already run, as part of your build. No version bumps, no breakage.
• Fix the unfixable: transitive dependencies, end-of-life packages and legacy systems that scanners mark "no fix available" are patched in place.
• Compliance ready: every sealed package is vulnerability-free for high and critical severities and fully compatible with the version it replaces, backed by a 72-hour SLA.

How Seal works

Reviewed by humans, tested by machines, validated by AI.

1. Identify the upstream fix the moment it lands.
2. Backport it into your exact version, tested and signed.
3. Deliver it automatically through a company-wide policy.

Take Spring4Shell (CVE-2022-22965). On end-of-life spring-beans 4.3.30, the legacy path is a major Spring 5.x migration and months of work. Seal delivers spring-beans 4.3.30-sp1 instead: the same version, with the vulnerability gone. Build, test, deploy.

Start in one step

Add the Seal CLI to your CI/CD pipeline. Seal replaces vulnerable packages with sealed versions automatically and opens a drop-in pull request. No manifest changes, no dependency conflicts, no developer workflow to relearn.

The results

• 90%+ lower remediation cost per vulnerability.
• Under 72 hours to a sealed version for critical CVEs.
• Weeks to minutes mean time to remediate.

"In the short amount of time, we're actually able to start seeing value from Seal Security. In essence, we're giving engineers back time that they deserve to continue developing our product and introduce new features." Kyle Kurdziolek, VP of Security, BigID

Seal covers application dependencies in all major programming languages plus Linux OS packages, with PDF attestations and VEX records for PCI DSS 4.0, SOC 2, DORA, ISO 27001, FedRAMP and HITRUST.
