HEAR FROM OUR CUSTOMERS

Build your application allowlist without lifting a finger.

Learning mode helped us to figure out what is our allowlist, and it built it for us without us having to do much of anything at all. Once we had that allowlist, then we were able to further benefit to know what our inventory of software was across departments.

See everything running in your environnment, instantly.

Within the first week of implementing ThreatLocker, we were able to view our entire inventory of applications—something my team always had to do manually. Within an hour or two were able to see every learned application on our system... that doesn't happen very often.

Ismael Hernandez

Vice President of IT

TLG Peterbilt

Get a clear view of application usage and exposure.

The advantage of using ThreatLocker in our organization is we now have a much better understanding of the applications that run on our estate and the potential risks of using those applications. And it helps us inform our risk score as an enterprise.

Jeremy Parsons

Technical Architect

Heathrow Airport

Get real peace of mind for your IT team.

With ThreatLocker, we have the ability to centralize disparate elements in the security stack, and support from the Cyber Hero team is bar none. Leveraging ThreatLocker allows me to sleep soundly at night because I know that I'm always one step ahead of threat actors.

Jack Thompson

Director of Information Security

Stop lateral movement inside your network.

Our servers were vulnerable once someone gained access to the network. ThreatLocker was the solution we needed. The platform makes me more conscious of what's coming in and out of our network... It gave me an opportunity to look behind the scenes.

Pierre Anyansi

Advanced Medical Transport

Go beyond what an antivirus could ever do.

The ThreatLocker solution was perfect for us.  With ThreatLocker Unified Audit, we get a clear description of what is allowed or denied on our network, and why. If I had a choice between an antivirus and ThreatLocker, I'd take ThreatLocker all day long.

Jack Harbut

IT and Systems Manager

Stampede Meats

Control risk across your entire organization.

Before ThreatLocker, we had a lot of risk that we just couldn't control. Now, we're doing a better of a job of providing a secure environment for our patients, doctors, and manufacturers. We want to make sure we're really protecting our network. ThreatLocker lets us do that very well.

Greg Gootee

CISO / SVP of Information Security

Asembia

Customize your security to fit your environment.

What we liked about ThreatLocker was how each tool built on the last, allowing us to control exactly how granular we wanted to get with locking down our environment. We had explored other options, but wWith ThreatLocker, we were able to get everything we needed from one place.

Jeff Lutes

Executive Vice President of Technology

Orlando Magic

Revolutionize your cybersecurity with powerful best-in-class tools.

Prior to ThreatLocker, we didn’t have a solution in place to help with application whitelisting. Implementing it into our environment was truly game-changing because we’d never used anything like it before. It came in, took control, and significantly reduced our threat landscape.
