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 the WHM's Security Advisor (WHM >> Home >> Security Settings >> Security Advisor) interface.


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 in their Manage2 profile.

Purchase license

Click the tab that corresponds with your preferred purchase method:

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 Settings >> Security Advisor).
  3. In the KernelCare Security alert, click Upgrade to KernelCare. A new interface 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 server does not support KernelCare (for example, servers that run Amazon Linux).
  • Your hosting provider 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 and perform the necessary steps to log in to the desired cPanel Store account.




Verify and complete your purchase.

When you purchase a KernelCare license through the WHM interface, the system automatically selects the appropriate license type for your server and 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 successfully processes your order, a confirmation message will appear, and 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, and 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 Settings >> Security Advisor) again and the KernelCare notice will confirm that the installation succeeded.


To purchase a KernelCare license through Manage2, you must be a cPanel Partner.

Log in to Manage2.

Log in to your Manage2 account, and then navigate to the Add License interface (Dashboard >> Licenses >> Add License).




Enter the required license information.

In the Add License interface (Dashboard >> Licenses >> Add License), use the available text boxes and menus to specify the server's IP address, group, license type and term. Then, click Add License. A confirmation message will appear.
