Seal OS
Sealed APK, DEB, and RPM packages for Linux servers and containers, including EOL distributions.
Seal OS remediates vulnerabilities in OS-level packages and language runtimes (Node.js, Python, JVM, and others) on your Linux servers and inside your containers. It covers the system layer that sits below your application code.
Seal OS covers the major Linux distributions and their package families.
What it covers
OS package ecosystems:
APK (Alpine)
DEB (Debian, Ubuntu)
RPM (Red Hat, CentOS, RHEL, Fedora, Amazon Linux)
Open-source language runtimes installed via the OS package manager are also covered, including Node.js, Python, and the JVM.
Seal OS supports EOL distributions. When the upstream distribution maintainer has stopped releasing security updates, Seal continues to ship sealed package versions for the affected components.
How it is delivered
Seal OS applies fixes via the Seal CLI, in place. The CLI runs on your Linux servers, inside your container builds, or in standalone environments, and installs sealed versions of the affected packages where they live.
