Eliminating Service Interruptions & Non-Compliance Caused by System Reboots

On average, it takes 43 days to see a cyberattack once a patch is released for a critical or high priority vulnerability. Plus, only in 12% of cases, one team is fully responsible for patching a vulnerability - add at least 12 more days for the cooperative effort and search of that one genius guy.

KernelCare will take on most of the patching lifecycle tasks and complete them in four steps without system reboot.

Once this process is finished, KernelCare will fully protect the server's Linux kernels and shared libraries against all known attacks.

Allocates kernel memory loads new, secure code into it

Momentarily freezes all processes in a 'safe' mode

Modifies original functions and jumps to new secure code, ensuring old (vulnerable) code can never run

Unfreezes all processes and resumes
