Cheap KernelCare License - Shared KernelCare License from $3.00

Why KernelCare removes the reboot from kernel patching

KernelCare applies Linux kernel security patches without rebooting the server. TuxCare engineers backport each CVE fix into the exact kernel version you are running, compile it as a live patch, and ship it to your server. The kcarectl daemon loads the patch in memory, redirects function calls from the vulnerable code to the patched code, and pauses the kernel for roughly one millisecond — imperceptible to running processes. No reboot, no failover, no customer-visible downtime, no service restart, no dropped database connection.

What you actually get in the Cheap Shared KernelCare License

A single license activates KernelCare on a server with the full feature set: live patching on every supported kernel, the kcarectl daemon with the 4-hour patch cron, CloudLinux kernel support, rollback for any patch that misbehaves, and 40 plus Linux distribution coverage (RHEL 6 through 10, CentOS 6 through 9, AlmaLinux 8 and 9, Rocky Linux 8 and 9, Oracle Linux 6 through 9 including both UEK and RHCK kernels, Amazon Linux 1, 2, and 2023, Ubuntu 16.04 through 24.04 across every LTS line, Debian 9 through 13, CloudLinux 7 through 9, plus Virtuozzo, EuroLinux, Springdale, ROSA, and ALT, both x86_64 and ARM64). TuxCare maintains the software, ships updates through their standard channel, and your install pulls those updates directly from the vendor repo the moment they release.

Why the Cheap Shared KernelCare License costs less than going direct

KernelCare's direct pricing is per-server with tier breakdowns by feature depth. We resell those exact same keys through the same wholesale channel and pass the savings through. There is no feature difference between what you buy from us and what you buy from TuxCare directly. Same key, same updates, same vendor-direct support contract.

SLA impact — the operational cost saver

For a hosting provider, that matters more than almost anything else on the server. A typical data center with 100 production servers sees 10 to 15 critical kernel CVEs per year, and each one would normally trigger a planned reboot of 5 to 15 minutes. That's 8 to 25 hours of customer-facing downtime per year, plus the SLA credits and the support tickets that come with every reboot. KernelCare removes every planned reboot for kernel patching, which directly improves your SLA score and your on-call engineer's quality of life.

Distribution and architecture coverage

Coverage spans 40 plus Linux distributions. RHEL 6 through 10, CentOS 6 through 9, AlmaLinux 8 and 9, Rocky Linux 8 and 9, Oracle Linux 6 through 9 (both UEK and RHCK kernels), Amazon Linux 1, 2, and 2023, Ubuntu 16.04 through 24.04 across every LTS line, Debian 9 through 13, CloudLinux 7 through 9, plus Virtuozzo, EuroLinux, Springdale, ROSA, and ALT. Both x86_64 and ARM64 architectures are supported, so AWS Graviton instances and other ARM-based cloud servers qualify for the same patch coverage as traditional Intel boxes.

Patch cadence — hours, not weeks

Patch cadence is hours, not weeks. Critical CVEs (remote code execution and local privilege escalation in particular) ship within hours of the vendor release. High-severity CVEs go out within 24 to 48 hours. Medium and low-severity issues bundle into weekly or monthly releases to avoid patch churn. For a CentOS or RHEL server without live patching, the same CVEs would force a planned reboot window, and on a shared host that means minutes of customer-visible downtime that KernelCare removes entirely.
