SSL decryption with server apps


I am wondering about SSL decryption for server apps, i.e business applications that are running on servers, for which the proxy has been configured with ZENs directly (no proxy pac). When enabling SSL inspection, has someone experienced issues with this kind of app, for instance the app does not user the Zscaler certificate installed on the server and such ?

Thanks for you help,



Some apps work only with there own SSL Certificate. To prevent Zsacler from replacing the SSL Certificate you have to exempt the destination host/URL from Zscaler SSL inspection.

Hi Ben,

When using the Zscaler service, applications and websites that use public key pinning will fail to establish an SSL session and might not function correctly.

Thank you, Will look into the PKP and how it works with Zscaler.
