Overview

The UI will alert you about certificates nearing expiration and recommend replacing them beforehand:

Choose the certificate method you are using:

If you use Check Point's Managed Certificate with CloudGuard WAF as a Service, your certificates will renew automatically. However, they won't renew if the DNS ownership CNAME value has been removed from the DNS records.

You need to add the DNA ownership CNAME record provided.

  1. Log in to the Infinity Portal.

  2. Open the WAF application from the application menu.

  3. Navigate to the Profile page and choose the relevant SaaS Profile.

  4. Choose the domain you would like to replace the certificate to.

  5. Navigate to the Certificates & Domain Management section at the top of the menu.

  6. Add the CNAME record's name and value in the DNS records management in the DNS provider portal.

  7. Click Enforce.

When using BYOC with CloudGuard WAF as a Service, the WAF admin should manually replace certificates that are about to expire.

  1. Log in to the Infinity Portal.

  2. Open the WAF application from the application menu.

  3. Navigate to the Profile page and choose the relevant SaaS Profile.
