 # Configure HTTPS on an Azure Front Door custom domain using the Azure portal
 
 
-Azure Front Door enables secure TLS delivery to your applications by default when a custom domain is added. By using the HTTPS protocol on your custom domain, you ensure your sensitive data get delivered securely with TLS/SSL encryption when it's sent across the internet. When your web browser is connected to a web site via HTTPS, it validates the web site's security certificate and verifies it gets issued by a legitimate certificate authority. This process provides security and protects your web applications from attacks.

Azure Front Door by default automatically enables HTTPS to all your custom domains using Azure managed certificates. No extra steps are required for getting an AFD managed certificate. A certificate is created during the domain validation process.

+* An Azure pre-validated domain doesn't require domain validation because it's already validated by another Azure service. The managed certificate (Azure managed) is issued and managed by the Azure service. No extra steps are required for getting an Azure managed certificate. Azure Front Door doesn't issue a new managed certificate for this scenario and instead will reuse the managed certificate issued by the Azure service. For supported Azure service for pre-validated domain, refer to [custom domain](how-to-add-custom-domain.md).

 ### AFD managed certificate for Non-Azure pre-validated domain
 
-AFD managed certificates are automatically rotated when your custom domain uses a CNAME record that points to an Azure Front Door standard or premium endpoint.
+AFD managed certificates are automatically rotated when your custom domain uses a CNAME record that points to an Azure Front Door Standard or Premium endpoint.
 
 Front Door won't automatically rotate certificates in the following scenarios:
 
-* The custom domain's CNAME record is pointing to other DNS resources.
-* The custom domain points to Azure Front Door through a long chain. For example, if you put Azure Traffic Manager before Azure Front Door, the CNAME chain is `contoso.com` CNAME in `contoso.trafficmanager.net` CNAME in `contoso.z01.azurefd.net`.

 The domain validation state will become *Pending Revalidation* 45 days before the managed certificate expires, or *Rejected* if the managed certificate issuance is rejected by the certificate authority.  Refer to [Add a custom domain](how-to-add-custom-domain.md#domain-validation-state) for actions for each of the domain states.

-In order for the certificate to be automatically rotated to the latest version when a newer version of the certificate is available in your key vault, set the secret version to 'Latest'. If a specific version is selected, you have to reselect the new version manually for certificate rotation. It takes up to 24 hours for the new version of the certificate/secret to be automatically deployed.
