We are excited to announce the launch of Seal OS, the first holistic solution designed to automatically fix vulnerabilities in both Linux operating systems and application code.

Seal OS delivers long-term support for a wide range of Linux distributions, encompassing Red Hat Enterprise Linux, CentOS, Oracle Linux, Debian, Ubuntu, Alpine, and more. This support extends to various deployment models, including containers, virtual machines, and bare metal installations. By addressing 99% of Linux vulnerabilities and application code issues, Seal OS provides a robust solution that saves developers time, reduces operational risk, and enables enterprises to bolster their security posture without sacrificing operational efficiency.

Solving the Challenges of Securing Linux Environments

"Organizations today face mounting challenges in securing their Linux environments, particularly when dealing with end-of-life systems and legacy applications," said Itamar Sher, CEO and co-founder, Seal Security. "Our new solution transforms this complex challenge into a simple one-line solution, enabling companies to maintain security and compliance without disrupting their operations."

Key Features of Seal OS

  • Automatic Vulnerability Remediation – Fix vulnerabilities without upgrading the environment.
  • End-of-Life and Legacy Support – Ensure compliance and security even after a Linux distribution reaches end-of-life.
  • Protection for Legacy and Third-Party Applications – Secure hard-to-patch systems and third-party applications.
  • Compliance and SLA Support – Helps organizations meet FedRAMP, PCI DSS 4.0, NYDFS500, and other regulatory requirements.

Case Study: Major Railway Operator Secures Legacy Systems with Seal OS

A large North American railway company recently leveraged Seal OS to address critical security vulnerabilities in their locomotive control systems running on end-of-life Red Hat Enterprise Linux 6. Facing strict Transportation Security Administration (TSA) compliance requirements and the complexity of upgrading safety-critical systems, the company turned to Seal Security for a solution.

Seal OS enabled the railway operator to backport critical security patches to their existing RHEL 6 installations, effectively addressing vulnerabilities without the need for a full OS upgrade. This approach significantly reduced operational disruption, ensured TSA compliance, and provided substantial cost savings compared to a complete system overhaul.

Get Started with Seal OS

Seal OS is now available for enterprises looking to vulnerability-proof their Linux operating systems.
