NFR's Sentivist IPS uses a combination of hardware sensors, and software for managing. It ships with a Java-based management console, which is good for monitoring and configuring individual sensors.
RealSecure 7.0 is the result of the integration between RealSecure and the BlackICE NIDS sensor technology. It runs on a dedicated machine and acts as a NIPS sensor to monitor a network segment, looking for intrusions or suspicious activity. If an intrusion is suspected, it can respond by recording details of the event. It can notify the network administrator, reconfigure the firewall, or terminate the event.
