- Azure Front Door offers several predefined TLS policies. You can configure your AFD with any of these policies to get the appropriate level of security. These predefined policies are configured keeping in mind the best practices and recommendations from the Microsoft Security team. We recommend that you use the newest TLS policies to ensure the best TLS security.

For more information, see [Delegate a domain to Azure DNS](/azure/dns/dns-delegate-domain-azure-dns). Otherwise, if you're using a domain provider to handle your DNS domain, see [Create a CNAME DNS record](/azure/frontdoor/front-door-custom-domain).
