A network-based intrusion detection system (NIDS) is responsible for monitoring network traffic for signs of illegal activity. Detection is typically based on the identification of unusual network activity that matches known threats or attack-signatures.

Not sure about the "suspect activity" you mean.

If you want to monitor suspect bandwidth usage, you need a bandwidth monitor.

If you want to monitor suspect web/message/email activities, you need an internet monitoring product. Maybe you can try "WFilter Enterprise", it enables you to monitor internet activities of network computers from a mirroring port in your switch.
