Seal Security
The fix layer for the AI era
AI-powered platform that automatically fixes open source vulnerabilities in the exact versions you run without requiring upgrades or code changes.
Overview
A look at seal.security
Seal Security is an AppSec Remediation Agent that delivers verified, backported patches for open source vulnerabilities across application dependencies, containers, and Linux hosts. Rather than forcing upgrades or code changes, Seal ships production-ready patches for the exact versions you run, often before CVEs are publicly disclosed. The platform integrates with existing CI/CD pipelines and security scanners, enabling security teams to remediate vulnerabilities independently without disrupting development roadmaps.
Seal monitors upstream code repositories for security fixes that haven't yet been assigned CVEs, reproduces vulnerabilities, and backports fixes to the versions in production. Patches are built, tested, reviewed by security engineers, and validated by AI before delivery. The company supports all major programming languages including Java, Python, JavaScript, C/C++, Go, PHP, C#, and Ruby, as well as Linux distributions and package managers.
The platform enables autonomous remediation through AI coding agents via the Seal MCP server, which works with Claude Code, Cursor, and other MCP-aware clients. Organizations can apply company-wide patching rules, maintain compliance with FedRAMP, PCI DSS 4.0, NYDFS, HITRUST, and DORA, and patch end-of-life systems that no longer receive upstream fixes.

FAQ
- What is Seal Security?
- Seal Security is the AppSec Remediation Agent that delivers verified, backported patches for open source vulnerabilities in the exact versions you run. Seal ships patches before CVEs are published, across application dependencies, containers, and Linux hosts, without requiring upgrades, code changes, or engineering time.
- What is Seal Security's SLA for new vulnerabilities?
- Seal ships sealed versions before CVEs are published through the pre-CVE program, backporting security fixes as soon as they land upstream before a fixed version is released.
- What regulations and compliance standards does Seal Security help organizations support?
- Seal Security streamlines audit-readiness and continuous compliance for FedRAMP, PCI DSS 4.0, NYDFS, HITRUST, and DORA. The platform is certified with SOC 2 Type II and ISO 27001.
- How does Seal Security differ from other AppSec tools and AI-generated patches?
- Other AppSec tools focus on visibility or prioritization, while Seal focuses on remediation, actually fixing vulnerabilities instead of just listing them. Unlike AI-generated patches that require team review and ownership, Seal fixes start from upstream fixes, are backported to your version, built and tested, reviewed by security engineers, and validated by AI before shipping.
- How does Seal ensure patches won't break existing code?
- Seal uses community fixes with minimal changes, typically fewer than 10 lines of code compared to hundreds or thousands in version upgrades. All remediated versions undergo thorough testing, manual inspection by vulnerability researchers, and AI verification for breaking changes. Additionally, since the platform runs at build-time, all existing tests run against remediated versions for extra assurance.
