ThreatLocker Network Access Control (Endpoint NAC)
Managed ThreatLocker Network Access Control - endpoint-level firewall and segmentation that blocks lateral movement, isolates compromised hosts, and limits inbound and outbound traffic per device.
ThreatLocker Network Access Control turns every endpoint into its own enforcement point. Inbound and outbound traffic is governed by policy, not by hope that the network firewall caught it. Compromised hosts are isolated in seconds and lateral movement is denied by default.
We design the policy, build the trusted device groups, and operate the response when an isolation event fires.
Everything in this service. Nothing buried in fine print.

[ Why endpoint NAC ]
Lateral movement is how single infections become breaches
Once an attacker lands on one endpoint, the goal is to move sideways - to another workstation, to a file server, to a domain controller. Endpoint NAC denies that movement by default and isolates infected hosts at the OS level, where it actually matters, instead of waiting on a switch ACL to converge.
[ Anywhere ]
Policy that follows the user home
Traditional NAC stops at the office wall. ThreatLocker Network Access Control enforces the same policy whether the laptop is on the corporate LAN, a coffee shop, or the user's home network.
[ Industry use cases ]

[ Buyer checklist ]
What good looks like when you evaluate providers
Not every provider that lists this service on their website actually delivers it well. Use the checklist below when you shortlist partners so you can compare apples to apples and avoid the two most common traps: a low sticker price that hides scope gaps, and a polished sales cycle backed by an offshore delivery team you never meet.
If a prospective provider cannot answer these questions plainly and in writing, treat that as a signal. The right partner will welcome the scrutiny.
