How KernelCare Works
KernelCare delivers live kernel vulnerability patches to your Linux servers without reboots or maintenance windows. A lightweight agent checks for new patches every 4 hours and applies them to the running kernel in nanoseconds. It covers 60+ distribution versions, and most CVE patches ship within 10 days of disclosure. If you run CloudLinux or another supported distro, installation is a single command.
KernelCare Features
Automated Patching
The KernelCare agent runs on a 4-hour patch cycle. New security fixes arrive and apply silently in the background, with zero manual steps.
Live Patching
Patches load directly into kernel memory in nanoseconds. No reboot, no maintenance window, no interrupted connections.
Versatile Update Modes
Run it in automatic mode for hands-off production servers or managed mode when you want to review patches in staging first.
Easy Rollbacks
One command (kcarectl --unload) reverts all applied patches instantly, no reboot required.
60+ Distros Supported
CentOS, AlmaLinux, Ubuntu, Debian, RHEL, Oracle Linux, Amazon Linux, and more. One agent covers them all.

Common Questions
Which add-ons are best for Cloud VPS?
Most Cloud VPS buyers start with performance (LiteSpeed), control panel (cPanel/WHM), and security (Imunify360 or managed firewall) based on workload needs.
Do these add-ons work on App Hosting too?
Many App Hosting features are built in, so not every VPS add-on is required. Use App Hosting for managed platform defaults.
How is add-on billing handled?
Add-ons are billed at the rate and cadence shown on each product page. Usage-based add-ons (such as per-seat licenses) list the exact unit price. You can review current charges in the billing dashboard.
