ThreatLocker Certified Partner

Most security tools try to catch bad software after it shows up. ThreatLocker works the other way around: only approved applications run, and everything else is blocked by default. Add Ringfencing, Elevation Control, and Storage Control, and you also limit what trusted apps, admin rights, and USB drives can do.

The catch is that allowlisting has to fit your business, or it gets in the way. That’s where we come in. We start in Learning Mode, tune the policies with you, move to Secure Mode in stages, and handle approval requests with people who already know your systems.

Wondering if allowlisting fits your business? We’ll walk through it with you.

Will application allowlisting slow my team down?

Not if it’s set up right. We start in Learning Mode to see what your people actually use, tune the policies with you, and then switch to Secure Mode in stages. When someone needs something new, they request it and our team reviews it with the context of already knowing your environment.
