Updating the Legacy Proxy Domain Name

From December 31, 2022, Skyhigh Security has retired the legacy proxy domain used under Security Service Edge (SSE) and replaced it with the new domain.

Make sure you have updated the proxy domain name you are using in your SSE products and policies accordingly. The domain name syntax is as follows.

Syntax Remarks
<prefix>.c<customerID> For WPS2 Hybrid customers using Skyhigh Client Proxy (SCP)


Examples Remarks uk is the country prefix for the United Kingdom For WPS2 Hybrid customers using Skyhigh Client Proxy (SCP) with uk as the country prefix for the United Kingdom

For more information about the Hybrid migration, see Migrate from WPS to WPS2 (ePO Managed MCP Agent and Policy). For country and regional prefixes, see Configure Global Routing Manager Country and Region Prefixes.
