ForeScout NAC

ForeScout CounterACT® is a physical or virtual security solution that dynamically identifies and evaluates network devices and applications the instant they connect to your network.

Because CounterACT doesn’t require agents, it works with your devices—managed and unmanaged, known and unknown, PC and mobile, embedded and virtual. CounterACT quickly determines the user, owner, operating system, device configuration, software, services, patch state and the presence of security agents. Next, it provides remediation, control and continuous monitoring of these devices as they come and go from the network.



At ForeScout, we don’t believe in artificial barriers that limit your options and force vendor lock-in. CounterACT works with leading network infrastructure, third-party security and IT management solutions. It also offers flexible deployment and configuration options to match your company’s specific needs. Choose physical or virtual deployments or both, and centrally manage them with CounterACT Enterprise Manager.

Several features set CounterACT apart:

  • Agentless: No endpoint agents are required for authentication and network access control, allowing CounterACT to see and control managed, unmanaged and IoT devices.
  • Open interoperability: CounterACT works with popular switches, routers, VPNs, firewalls, endpoint operating systems (Windows®, Linux, iOS®, OS X and Android), patch management systems, antivirus systems, directories and ticketing systems—without infrastructure changes or upgrades.
  • Security orchestration: Optional modules orchestrate information sharing and policy-based security enforcement between CounterACT and leading IT and security management products.
  • 802.1X authentication, or not: Choose 802.1X or other authentication technologies such as LDAP, Active Directory®, RADIUS®, Oracle® and Sun. Hybrid mode lets you use multiple technologies concurrently.
