Experience the Only Rebootless Patching Solution that Truly
Delivers the Core Benefits that Rebootless Patching Was Designed for

Complete CVE
Coverage

KernelCare provides live patches for up to 100% of Ubuntu vulnerabilities, far surpassing the mere 5-10% coverage offered by Canonical Livepatch.

Supreme Stability
and Uptime

KernelCare keeps your Ubuntu systems running uninterrupted for as long as you choose, unlike Livepatch, which disrupts stability with rigid reboot deadlines.

Fully Rebootless
Experience

KernelCare offers rebootless patches for components that typically require reboots, like critical userspace, hypervisors, and IoT devices – which Livepatch doesn’t cover.

Vendor-Agnostic
Solution

Unlike Canonical Livepatch, which limits rebootless patching to only Ubuntu systems, KernelCare delivers live patching for your entire Linux server fleet.

Find out how AppSignal switched from Livepatch to
KernelCare Enterprise to achieve fewer reboots

“With Livepatch, it was always vague when we should reboot and if we should
reboot. You have to reboot in some cases, but not in others, and nobody could
really tell us the difference. We couldn’t really figure it out, and nobody at
Canonical was able to tell us.”

-Thijs Cadier, Co-Founder of AppSignal on Switching from Canonical to TuxCare
