Reduce exposure to unauthorized access
Ensure only verified users on trusted devices can initiate connections—minimizing risk from compromised credentials and lateral movement.
Enforce Zero Trust across hybrid environments
Apply consistent, device-level policies across offices, remote endpoints, data centers, and cloud workloads.
Protect internal services without exposing them
Remove reliance on open inbound ports and keep critical systems hidden from unauthorized connection attempts.
With modern networks extending far beyond the traditional perimeter, legacy access methods like VPNs are becoming inefficient and risky. ThreatLocker enables you to enforce Zero Trust at the network level, ensuring that every connection is intentional, verified, and secure.

By shifting control to the device level, ThreatLocker allows you to define exactly who can access what, based on user identity, device, and context. Whether users are in the office, traveling, or working remotely, they experience seamless access while your network remains locked down.

No inbound ports or unnecessary exposure. And no complex infrastructure changes.

Definition (benefit-focused)

Zero Trust Network Access (ZTNA) with ThreatLocker is a modern approach to securing connectivity that ensures only authorized users on approved devices can access specific internal resources, without exposing your network to the internet.

The benefit: You dramatically reduce your attack surface while simplifying secure access for users.

How it works

Start with deny-by-default
All network traffic is blocked unless it explicitly matches your defined policies, automatically reducing exposure.
Define access policies
Specify:

Which users can connect.

Which devices are approved.

Which resources are accessible.

Which ports and protocols are allowed.

Optional time-based and posture-based conditions.
Enable secure, seamless connections
Both endpoints and servers establish outbound connections, eliminating the need for open inbound firewall ports or VPNs.

Access is granted only when identity, device, and policy all align.
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.
