Prevent unknown and untrusted code from ever running. By controlling what applications can run, you can stop ransomware, zero-days, and fileless attacks before they ever execute. That means your other endpoint defenses are quieter, systems stay faster, and your security team spends less time chasing alerts.
Most cybersecurity tools focus on detecting threats after they’ve breached your environment. ThreatLocker prevents them from ever executing.
Stop reacting to threats, and start preventing them from the outset. Protect your environment with a unified Zero Trust platform that stops attacks before they start.
“ThreatLocker provides that extra key to block anomalies that nothing else can do. It gives me a great deal of comfort as an IT director.

Jeremy Parsons, Technical Architect, Heathrow Airport

ThreatLocker Detect, a powerful Endpoint Detection and Response (EDR), relentlessly analyzes telemetry, behavioral patterns, and Indicators of Compromise (IoCs).
Say goodbye to critical time delays and hello to rapid threat neutralization. When suspicious behavior strikes, ThreatLocker automatically isolates compromised machines, cutting off lateral movement and stopping the attack before it spreads through your network.
Detect’s functionality is backed by a robust catalog of policy actions that respond instantly at the endpoint by:
Using ThreatLocker Detect versus other EDR solutions has given us fewer false positives and the triggers we do get are more insightful than we’ve ever received before.
