KernelCare Security Patching

KernelCare automatically installs security updates to running kernels – so your servers don’t need rebooting. When the next vulnerability hits, whether small or earth-shattering like Meltdown, your servers get protection without downtime. Plus it gets rid of the following Admin headaches:

  • Avoid complicated planning of coordinated, scheduled downtime for your customers
  • Stop troubleshooting and updating servers at night and on weekends
  • Keep kernels secure as updates are automatically installed within hours of the patch release, not a month later.

Free to use for 30 days – purchase required for continued kernel live-patching.
