InfoExpress CyberGatekeeper: NAC Product Overview and Insight

See the complete list of top 9 network access control (NAC) solutions.

Company Description

Founded in 1993 and based in Mountain View, Calif., InfoExpress provides enterprise network access control for mobile computing and bring-your-own-device (BYOD) networks. It is a privately held company.

Product Description

InfoExpress offers CyberGatekeeper, a family of NAC products that control access to the network by auditing devices before granting access to the network. The company’s solutions include Dynamic NAC for Windows, which is software that installs on Windows servers and enables clients to monitor networks and add network access control. InfoExpress Dynamic NAC requires no network changes and is fast to deploy. It offers centralized management, flexible policies, granular quarantining and monitoring, and remediation of unhealthy systems. It continuously checks all devices on the network. Dynamic NAC hardens the existing network by making some of the PCs enforcers that monitor and control access to the network. These enforcers report and quarantine unauthorized devices, like rogue endpoints and unhealthy PCs. Unhealthy PCs can rejoin the network after automatic or manual remediation brings them into compliance. Further features include domain authentication, and centralized policy updates and reporting.


It has an agentless NAC option, which is the easiest to deploy but offers less control and fewer inspection capabilities. Agent-based NAC can perform much deeper inspection and remediation.
