I have received answer from Sophos Commerce that the EOL SATC functionality is now included in Intercept X for Server and will be rolled out to different users in phases as of July 1th.
Is there a document outlining the chances in Intercept X?
After the rollout happend, which is not on 01.07, instead the rollout phase will take more time (staging etc.).
Central shows Intercept X for server now as the XDR version. So I set the register keys for adding Satc to Intercept X on the RDS, then restarted. Via the XG console I added the IP of the RDS.
Live connections on the XG still show as STAS and not as Thin Client. Log viewer under authentication shows the user succesfull authenticated to the XG firewall tru AD with CTA as Auth Cliënt from the RDS.
Still when using the XG as web proxy or direct internet acces I get the login portal.
The SATC replacement is not done. And you need to exclude the SATC Server from STAS.
