The Cisco Secure Client Zero Trust module uses HTTPS to communicate with the client-based Secure Access Zero Trust client certificate revocation services. We recommend that you allow all traffic on ports 80 and 443 over TCP for the Secure Access Zero Trust Client Certificate Revocation services domains.
