Secure remote and hybrid workforces
Protect users connecting from home, travel, or unmanaged networks with consistent, device-level firewall enforcement.
Prevent unauthorized lateral movement
Stop rogue devices and attackers from accessing internal systems by enforcing strict, identity- and device-based network controls.
Gain full visibility into network activity
Monitor every connection across endpoints and servers from a single console—no blind spots, no guesswork.
Security must follow the device, wherever it goes.

ThreatLocker® endpoint firewall gives you the ability to enforce granular, device-level firewall policies across your entire environment. Whether users are in the office, at home, or on the road, you maintain complete control over who can connect, what they can access, and when.

With centralized visibility into all network activity and dynamic policy enforcement, you can harden your environment against unauthorized access—without adding complexity.

Definition (benefit-focused)

ThreatLocker endpoint firewall is a host-based firewall for endpoints and servers that gives you complete control over network traffic by enforcing access based on device, IP, port, and policy.

The benefit: You eliminate unauthorized connections while maintaining flexible, scalable control across your entire environment.

How it works

Gain complete visibility
Monitor all inbound and outbound connections across endpoints—see the source, destination, and behavior of every request.
Define and apply policies centrally
Create firewall rules from a single console, controlling access by:

Port.

Source IP.

Device identity.

Dynamic ACLs that adapt as environments change.
Enforce access in real time
When a connection is attempted, ThreatLocker verifies whether the source is authorized.
If approved the connection is allowed automatically.
If not the connection is blocked and remains invisible.
Apply ThreatLocker® host-based policies to keep your data and endpoints protected wherever users connect.

Define exactly who can connect and when. Gain complete visibility and security across offices, homes, and remote locations alike, and harden your environment against unauthorized access.
