Updating the Legacy Proxy Domain Name
From December 31, 2022, Skyhigh Security has retired the mcafee-cloud.com legacy proxy domain used under Security Service Edge (SSE) and replaced it with the new skyhigh.cloud 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>.wgcs.skyhigh.cloud | |
| <prefix>.c<customerID>.hybrid.skyhigh.cloud | For WPS2 Hybrid customers using Skyhigh Client Proxy (SCP) |
| Examples | Remarks |
|---|---|
| uk.c12345678.wgcs.skyhigh.cloud | uk is the country prefix for the United Kingdom |
| uk.c12345678.hybrid.skyhigh.cloud | For WPS2 Hybrid customers using Skyhigh Client Proxy (SCP) with uk as the country prefix for the United Kingdom |
