Do you want to use KernelCare for rebootless kernel updates? But what if you are running an unsupported distribution? What if your kernel is custom, self-compiled, special, or just old?
KernelCare provides Custom Kernel Patching so that your company can benefit from live patching service for your kernel. The experts on our security and kernel development team can update your kernels using KernelCare technology to apply patches to the running kernel without the need to reboot servers.

As patch creation requires a strong background in kernel development as well as a powerful toolset to prepare and test the patches, the team at KernelCare by CloudLinux is best qualified to keep your kernels updated. The group of highly skilled kernel developers will prepare patches for your distribution, embedded devices or server fleet. We can work with kernels as old as 2.6.18, 32bit and 64bit, all the way up to the latest kernels.

Do you have custom compiled kernels or just an unusual distribution? We can handle it. Our team can do security fixes, bug fixes, performance enhancing and stability fixes or new features – whatever your requirements are.
