What is network access control?

Network access control, or NAC, is the set of tools, processes and protocols that govern access to network-connected resources. It involves access control solutions for different types of resources, including conventional PCs and servers, network routers, IoT and OT devices, and the data that travels over a network. Most organizations view NAC as a critical component of a network security strategy.

NAC helps to prevent unauthorized devices from joining a network, and with key integrations can identify existing devices so that network administrators can properly secure or remove them. Some NAC solutions can also provide information about whether compliance with data privacy laws is required.

While NAC governs access to connected resources, some users choose to complement NAC with security measures that provide deeper visibility into IoT and unmanaged devices.

Ordr Systems Control Engine (SCE) augments NAC solutions by continuously identifying all connected devices in the network, profiling device behavior and risks, and then automating the appropriate action. Ordr takes the tedious work out of creating and implementing policies by generating them dynamically for any vulnerable device or group of devices and enforcing them on network access controls (NACs).
