    Comparing the best intrusion prevention systems

    Network intrusion prevention systems (IPSes) are enterprise security technologies dedicated to monitoring and analyzing network traffic for suspicious activity. Unlike a firewall, which is generally based on a ruleset that specifies network traffic flow restrictions, an intrusion prevention system examines the headers and contents of network traffic for activity that is deemed too risky, and then stops the current communications containing such activity. They may directly force suspicious activity to terminate, or may trigger reconfigurations in other enterprise security controls to accomplish this.
