I'm seeing a lot of products, such as SQL Server, coming out with opt-out spyware. This is marketed as "Telemtry" or "Customer Experience Improvement Program (CEIP)".
Obviously, this can currently be disabled in the software itself. What settings on the firewall can I take to block this kind of communication with Microsoft (ip/port) blocking?
You can block
You can see that's what they're communicating to in the client-side telemetry with
mssql-cli
, andvscode-extension-telemtry
. And, for SQL Server, you can find out how to turn them off on the client and server here
