How to Purchase a KernelCare License

Last modified: May 2, 2024


KernelCare automatically updates your system’s Linux® kernel without the need for a reboot. cPanel & WHM servers allow you to purchase a license for KernelCare from WHM’s Security Advisor interface (WHM » Home » Security Center » Security Advisor).

  • Before you purchase and install KernelCare, make certain that your system possesses a compatible kernel. To do this, read the KernelCare documentation.
  • To install and run KernelCare, you must disable Secure Boot if you enabled Secure Boot previously.
  • You can only install KernelCare on systems that run one of the following operating systems:
    • CentOS 7.
    • Red Hat® Enterprise Linux® (RHEL) 7.
    • CloudLinux™.
    • AlmaLinux.
    • Rocky Linux™.
    • Ubuntu®.

For the latest information about the operating systems that WebPros International, LLC supports, read our Installation Guide documentation.


Hosting providers can configure whether this option sends the purchaser to the provider’s custom URL, an email address, or the cPanel Store. They can also disable the banner for their licensed servers from Manage2’s Update Company Information interface (Manage2 » Company » Update Company Information).

Purchase license

Purchase from WHM

Initiate the license purchase process.

On the server for which you wish to purchase a KernelCare license, perform the following steps:

  1. Log in to WHM as the root user or as a reseller account with root-level privileges.
  2. Navigate to WHM’s Security Advisor interface (WHM » Home » Security Center » Security Advisor).
  3. In the Upgrade to KernelCare alert, click Get KernelCare for $, where $ represents the monthly price of the KernelCare license. The cPanel Store will appear.

If the KernelCare Security alert does not appear in the list of security alerts, one of the following conditions exists on your server:

  • Your virtual server does not support KernelCare, because the host node controls the kernel. For example, if your virtual machine is on an OpenVZ or Virtuozzo platform.
  • Your system’s kernel is unsupported.
  • You enabled Secure Boot.
  • Your hosting provider has disabled KernelCare purchases.
  • A KernelCare trial license currently exists on your server.

Log in to the cPanel Store.

If you have already logged in to your cPanel Store account, the system will request access to this account. Verify that the interface displays the correct cPanel Store username and server name, and then click Allow Access. A new interface will appear.


To log in as a different cPanel Store account, click Sign In as a Different User. Then, perform the necessary steps to log in to the desired cPanel Store account.

Verify and complete your purchase.

When you buy a KernelCare license through the WHM interface, the system automatically selects the appropriate license type for your server. It also detects the IPv4 address to license. Currently, you can only purchase monthly licenses through the WHM interface. Verify your license order, accept the legal agreements, enter or select the desired payment information, and then click Pay Now.

  • After the cPanel Store processes your order, a confirmation message will appear. You will receive an invoice email from the cPanel Store. After you successfully purchase a license, the KernelCare License banner will no longer display in the WHM interface.
  • If the cPanel Store experiences problems with your order, an error message will appear. You may receive emails from cPanel Customer Service to help you resolve the issue.


Your server will automatically download and install KernelCare. To verify this, navigate to WHM’s Security Advisor interface (WHM » Home » Security Center » Security Advisor) again and the KernelCare notice will confirm that the installation succeeded.
