IntruProT IPS beta, an enterprise-class intrusion prevention system, is free of cost for small and mid-sized enterprises. Intrupro IPS prevents external and internal intruders from exploiting vulnerabilities and misusing privileges. It uses multiple detection methods including signature detection, protocol anomaly and traffic anomaly. IntriPro IPS plugs into the network, either in front of or behind an existing firewall, without changes to the overall network configuration. It also identifies bandwidth intensive peer-to-peer applications such as instant messaging.”]
