ThreatLocker

ThreatLocker takes a deny-by-default, zero trust approach to endpoint security, allowing only explicitly approved applications to run and blocking everything else, including ransomware and unknown threats. Instead of trying to detect bad software after it runs, its allowlisting, ringfencing, and storage control lock down what applications can do, which files they can touch, and how they interact, dramatically shrinking the attack surface. This proactive model stops attacks that signature- and behavior-based tools miss.

The platform gives IT teams and MSPs granular control and visibility over endpoints, with a support team that helps approve legitimate software so security does not break productivity. It is widely adopted by MSPs protecting client environments. ThreatLocker is designed for IT and security teams and MSPs that want strong, proactive, zero trust endpoint control to prevent ransomware and limit what runs on their systems.
