End-of-Life Linux


An unsupported operating system is a ticking time bomb.

An unsupported operating system becomes more dangerous as time goes by.

Linux kernels, libraries, and packages are frequently patched to guard against new security vulnerabilities. When you use a Linux distribution that is no longer supported by the vendor, you will not receive corresponding updates. Your operating system will not be protected. That puts your servers, your data, and your business at risk of a cyberattack.

Protect your servers and stay compliant with CloudLinux Extended Lifecycle Support services. A simple, low monthly fee buys you the time you need to migrate to a supported operating system or to upgrade to the newest version of your current Linux flavor.

What is included in the
Extended Lifecycle Support?


Patches available soon after CVEs go public

The CloudLinux team is famous for quickly delivering patches for critical CVEs right after the CVE goes public.

Years of support

CloudLinux ELS lasts 4 years beyond EOL dates at a minimum. It gives you ample time to migrate.

No, you will continue to rely on your preferred operating system. We will just continue updating the packages for the operating system you love with security fixes that keep your OS environment safe and secure.
CloudLinux continuously monitors critical Linux kernel vulnerabilities and security concerns associated with the OS covered by your Extended Lifecycle Support contract. We release patches for security risks and general maintenance issues as soon as they are completed and tested.
Before each package goes into the production repository, we run several testing processes to verify that our update has zero unintended consequences. We also maintain a stable beta repository that we use for testing.
KernelCare would automatically apply our patches live in memory while your systems are in operation. However, if you prefer to patch manually, you can simply continue to do so using yum as you usually would.

Stop taking risks with an unsupported OS.

Migrating to the newer OS version is always challenging, but vulnerabilities in unpatched OS can lead to an expensive breach. Don’t wait.
Take control of your OS upgrade strategy with Extended Lifecycle Support from CloudLinux.
