Which version of TLS does EventSentry use between the collector and its agents?

Since EventSentry utilizes the TLS capabilities of the OS, the version of TLS being used between the collector and the agents depends both on the version of Windows the collector is running on, and the version of Windows the agent is running on.

By default, client (agent) and server (collector) will negotiate the following TLS parameters illustrated in the matrix below. You can also review event 910 (on the agent) to verify which TLS parameters were negotiated.
