Start with an explicit access decision.
NIST’s Zero Trust Architecture rejects implicit trust based only on network location or asset ownership. A device being inside the office is not enough to justify unrestricted access.
EasyNAC contributes device visibility and network access enforcement to that broader approach. It helps identify connected devices, use the available security context and apply the access policy selected for the protected network.
Build context for managed and unmanaged equipment.
Agentless discovery helps establish what is connected, including printers, cameras and other devices that cannot run a NAC agent. Profiling supplies useful characteristics; supported directory and security integrations add management information.
These inputs answer different questions. A profile suggests device type. AD membership or XDR management supplies evidence used by a trust rule. Avoid treating a recognizable MAC address or operating system alone as strong authentication.
Authorize managed devices with Auto Trust Policy.
Connect Active Directory and a supported XDR platform. The AD joined machine and XDR managed machine checks can automatically authorize devices that meet the configured policy.
Give other device types the access they need through defined rules and approvals. Guest equipment, shared printers and critical systems do not necessarily provide the same evidence as a managed workstation. Keep exceptions clear and review them.
Turn the decision into network access.
EasyNAC uses ARP-based enforcement on protected IPv4 network segments. The configured access control list controls traffic involving devices that require restriction. Unknown-device protection and a configured captive portal can support registration and remediation.
This agentless approach does not require introducing 802.1X on the switches or deploying a dedicated NAC agent to every endpoint. Existing 802.1X authentication can work alongside EasyNAC. Confirm the covered networks and enforcement outcomes in a pilot.
Respond when device conditions change.
Trust should not be a permanent label. Supported security integrations, compliance checks and detection signals can inform later access decisions. Automated Threat Response connects selected alerts to a configured network restriction.
Test the full sequence: a device starts with approved access, a relevant condition changes, the intended response occurs, and access is restored after resolution. Explore threat-response examples →
Keep the wider Zero Trust architecture in view.
NAC addresses device context and access on the networks it covers. User identity, application authorization, data controls, endpoint protection and recovery still have their own roles. Deploying EasyNAC alone does not complete a Zero Trust program.
Begin with a practical network objective, such as restricting unknown branch devices or recognizing AD/XDR-managed computers. Use the Evaluation Kit to record the access outcomes you need to demonstrate.
