For mobile or roaming users, the GlobalProtect endpoint provides the user mapping information to the firewall directly. In this case, every GlobalProtect user has an app running on the endpoint that requires the user to enter login credentials for VPN access to the firewall. This login information is then added to the User-ID user mapping table on the firewall for visibility and user-based security policy enforcement. Because GlobalProtect users must authenticate to gain access to the network, the IP address-to-username mapping is explicitly known. This is the best solution in sensitive environments where you must be certain of who a user is in order to allow access to an application or service. For more information on setting up GlobalProtect, refer to the GlobalProtect Administrator’s Guide.
