We get asked from time to time from our customers about how to add custom application labels on your traffic.

LANGuardian fingerprints each traffic flow on the network to identify the application protocol in use (HTTP, SMB, SMTP etc). The Top Protocols report is the summary report for viewing network usage by each application protocol.

Some protocols cannot be fingerprinted by LANGuardian, such as custom/in house applications, encrypted protocols, or protocols which LANGuardian does not recognise. The Custom Flow classification settings allows the user to apply a custom label to all traffic flows matching particular attributes, such as source and destination IP address, source and destination port number etc. The flow is then saved in the database with that custom flow label; an example usage would be to label all backup traffic as such, as this traffic typically cannot be fingerprinted by application recognition engines.

Take a few minutes to watch this video which explains the process ​of Creating custom application labels in LANGuardian.
