What is one key benefit of deploying a Private Service Edge (PSE) in a customer’s...

The ZDTE study content groups Private Service Edge under Advanced Platform Services, explaining that PSEs host the same Zero Trust Exchange policy and inspection engines, but run as customer-managed service edges inside data centers or large offices. They are designed to give on-premises users a “local on-ramp” to ZIA and ZPA services while still enforcing full zero-trust policy.

The documentation emphasizes that PSEs do not replace App Connectors for ZPA; connectors are still required to establish inside-out application connectivity. Nor do PSEs remove the need for ZTNA policies—those policies remain central and are simply enforced closer to the user. Encryption is also preserved end-to-end; there is no “unencrypted fast path” described in the reference architecture.

Instead, the primary benefit highlighted is performance and user experience: by enforcing ZIA/ZPA policies at a local PSE rather than a distant public service edge, organizations reduce round-trip latency and keep traffic on optimal paths while maintaining identical security and access controls.
