Note: Discover does not support the use of the Diffie-Hellman cryptographic protocol and recommends configuring your web servers to not use it.

Note: The Unica Discover Network Capture Application supports the SSL Session Ticket extension. If you enable this extension on your web server, upgrade to one of the supporting builds:

TLSv1.1
TLSv1.2

Note: The Unica Discover Network Capture Application expects to see the start of all TCP connections. If TCP persistent connections are used by any server that is feeding data to the DNCA, then latency can be introduced in the capture of sessions, and data can be lost.
