What users say

“Intelligent onboarding using learning mode to capture the current software and typically used files in an environment makes it seem less [daunting] to implement a zero trust endpoint protector that lets you sleep easily at night.”
Verified user SoftwareReviews
“It is a love-hate relationship with ThreatLocker; everybody hates it because it causes so much need for user input to request to allow applications, but it is a necessary evil because security is paramount.”
Verified user PeerSpot
“One downside of ThreatLocker is that it can be a bit complex to set up and manage, especially for smaller businesses or teams without dedicated IT resources. The pricing of this tool is comparatively high as compared to the other tools.”
