ThreatLocker Network Access Control: Enforce Least Privilege Across Your Network

Traditional firewalls aren’t enough to stop lateral movement and internal threats. With ThreatLocker Network Access Control (NAC), you define exactly which devices, users, and applications are allowed to communicate—everything else is blocked by default. Enforce Zero Trust policies across your network and reduce your attack surface dramatically.

Why Network Access Control (NAC) Is Important

Stop Unauthorized Communication Before It Starts

ThreatLocker NAC provides microsegmentation at the endpoint level, allowing you to restrict communication between systems unless explicitly permitted. Instead of relying on traditional network security that trusts everything behind the firewall, NAC enforces Zero Trust by requiring verified rules for every connection. The result: tighter control, stronger security, and better visibility into east-west traffic.
Control Connections, Not Just Endpoints

Why ThreatLocker NAC is a Game-Changer for Internal Network Security

Many cyberattacks spread by moving laterally through your network. ThreatLocker NAC stops that movement by locking down all traffic between devices, unless an allow policy exists. Whether you're protecting against ransomware, insider threats, or compromised credentials, NAC puts you in charge of every connection attempt.

Default Deny Networking

Block all device-to-device communications unless explicitly allowed.

Microsegmentation at the Endpoint

Enforce granular communication rules without needing expensive network hardware.

Application-Aware Rules

Allow only specific applications to access designated systems or ports.

Policy-Based Access Control

Define custom rules by user, device, group, location, or time of day.

Full Traffic Logging

Monitor all attempted connections for auditing, visibility, and threat detection.

Integration with the ThreatLocker Suite

Seamlessly works with Application Control, Ringfencing™, and Elevation Control for unified endpoint protection.
