Some organizations require private IP addresses to skip authentication of headless
systems that can't authenticate, set up security policies, and get visibility of the
traffic on Prisma® Access Explicit Proxy. You can now accomplish these tasks by
leveraging the private IP addresses of the systems in your branch locations that are
forwarding traffic to Explicit Proxy
using Proxy mode. Proxy mode on remote
networks helps to secure outbound internet traffic for users and servers in your
branches that need PAC-based connection method due to networking or compliance
reasons.
