After Heartbleed and POODLEsecurity is probably at the top of your agenda. With PRTG Network Monitor you can check SSL connectivity to your devices' ports using the SSL Security Check sensor (beta).
The SSL Security Check sensor tries connecting to the specified TCP/IP port with various versions of SSL/TLSand shows whether a particular protocol is supported or not. You will want strong protocols here!
This sensor will show you immediately whether a secure connection is possible.
Sensor down: No secure protocol is available
Warning status: Only weakly secure SSL 2.0 and 3.0 protocols are available
Sensor up: Protocols ensuring strong security for your connections are available (TLS 1.0/1.1/1.2)
This way you gain an overview of the security degree and encryption types that are supported for the connections you plan to establish. Now go and get your network on the safe side!
