Each Ubuntu release has security updates provided to all users for five years from the initial release date. Ubuntu also releases new LTS releases every two years. For customers building on rapid release cycles using the latest technologies can be assured their systems will remain patched against security vulnerabilities simply by upgrading to the latest LTS release.
For customers operating longer development cycles, or wishing to keep systems in production for longer production lifespans, Canonical offers Extended Security Maintenance.
ESM provides ongoing security fixes for the kernel and essential packages for a specific time-frame beyond the five-year security maintenance window.
ESM is a benefit of Ubuntu Advantage and can also be purchased stand-alone.
