Register today for Zero Trust World 2026!

Take control of your environment

No unknown software slipping in, no silent installs happening in the background, and no ransomware quietly starting to encrypt. Take control of your environment with clear, enforceable allowlisting application control.
Stop ransomware at first run.
If it’s not approved, it doesn’t execute. And no execution means no encryption.
Eliminate shadow IT instantly.
Unauthorized tools can’t run. Simple as that.
Enforce application control for compliance.
Deny-by-default execution satisfies NIST, CMMC, CIS requirements, Essential 8 guidelines, and more. Plus, audit-ready data is available at your fingertips. See us for a list of compliance frameworks we support.

ThreatLocker allowlisting is practical, fast to deploy, and built to scale. You can now secure your environment in hours to days, not months to years, without slowing your business down. You no longer have to choose between security and usability. Let’s simplify, scale, and enforce your Zero Trust environment now.

A powerful deny-by-default allowlisting solution that makes application control simple and fast. Only approved software runs, everything else, including ransomware, is blocked by default.

Make better decisions with insights into application behaviors and adoption around the world

When evaluating an unknown app, access Threatlocker insight capabilities to see how often an application is used, how many environments it runs in, and whether other admins have allowed or blocked it. You can instantly see peer data from millions of anonymized endpoints worldwide, threat history, and reputation trends, then generate suggested allowlisting policies based on real-world behavior.

Result: Confident, data-driven allowlisting decisions that save you hours of analysis.

Here’s how it works:

Deploy ThreatLocker agent:
Automatically catalog all apps and dependencies. With 13,000+ of pre-built apps recognized, you’ll gain immediate visibility, streamline your application list (a potential major efficiency across your organization), and get policy suggestions on the fly. No more manual list building or creating policies from scratch, a significant reduction in your operational burden.

Approve what you need
Select the apps you want to run and approve them with one click. With your environment now secured, no unapproved apps, scripts, or libraries can execute.

Easily add new apps
When needed, your users can request new app access via a popup. IT can approve internally, or ThreatLocker can handle it for you through the Cyber Hero® team, that responds in about 60 seconds. Plus, with the ThreatLocker application store, users swiftly access trusted apps or alternatives to download and deploy with minimal operational disruptions and without compromising your Zero Trust environment.

Implementing ThreatLocker established our allowlist fast and with little manual work. It also surfaced a reliable software inventory across departments for audit and cleanup.

Your benefits

Gain full visibility and control
See every app, dependency, and update in your environment. Control exactly what runs, when, where, and by whom.

Take control of your security ops
Set policy expirations. Slash manual work and support tickets. Need to run a network scanning tool every Friday at 5 p.m.? Permit it! Only then, only for that.

Eliminate Shadow IT
Only approved applications can run, blocking rogue installs, unsanctioned tools, and hidden software across your network.

The results?

A lightweight and powerful deny-by-default application allowlisting solution, faster to deploy and easier to scale.

You are now in control:
Only approved applications run in your environment. It’s a simple, binary approach: If it’s on the list, it runs. If it’s not, it doesn’t. All with minimal resource use and greatly reduced operational friction. Because knowing what you need is way easier than chasing down everything you don’t.
