Keep Linux Kernels Up-To-Date and Running Without Interruptions
KernelCare, the world's finest defender of Linux kernels, puts an end to rebooting servers just to apply the latest kernel updates. It ensures that you never miss security patches, and your kernels are always up-to-date.

KernelCare eliminates the need for staying up at night to deliver patch updates, or coordinating downtime with your business units and various IT departments and locations.

With KernelCare, security updates are applied automatically to a running kernel. Rebootless installation of security patches takes nanoseconds, doesn't alter the performance of servers, and quickly delivers a better, more secure Linux.
