Rollout: ForeScout's CounterAct
ForeScout CounterACT 6.0 is an agentless, out-of-band, network-access-control product that combines RPC assessment with passive monitoring for malicious behavior. The powerful and flexible policy definition engine can define complex conditions and use those conditions to select and apply the appropriate policy. Through continuous monitoring, HTTP intervention and scheduled scans, CounterAct deploys policies dynamically, as a host's condition changes.
CounterAct uses passive monitoring, vulnerability-assessment scans and host inspection to assess the host's health, and grant or deny access to network resources. Passive analysis detects unauthorized network activity that might be missed by a host-assessment, antivirus or other host-protection product. Devices from ConSentry Networks, Nevis Networks and Vernier Networks also use this style of monitoring, but are inline products. Because CounterAct works out of band, it won't degrade network performance. Other NAC products, such as Check Point Software Technologies Integrity and InfoExpress CyberGatekeeper, can be deployed out of band, but require agents on every host and don't do passive monitoring.
