What ThreatLocker is

ThreatLocker is a cloud-delivered security platform built around a default-deny approach: only explicitly approved activity is allowed. It is designed to stop ransomware, rogue applications, and zero-day exploits before they run. Its capabilities include allowlisting, Zero Trust Network Access, endpoint firewall, web content control, privileged access management, patch management, external storage device control, data storage access control, real-time EDR threat detection, MDR, and controlled application testing. The platform requires an agent on each computer, with installation guidance for Windows, macOS, and Linux. Web Control policies currently support Windows and Mac agents; Linux support is coming soon. Browser extensions support Chrome, Edge, Safari, and Firefox. ThreatLocker logs executable activity, file access, and network communications in an indexed, searchable audit trail. The company says these records support frameworks including SOC 2, HIPAA, PCI-DSS, and ISO 27001. Integrations include ConnectWise, Kaseya, SolarWinds, and Datto. Pricing is available on request and depends on endpoint count, application landscape, and control needs. There is no free plan, but a 30-day trial is listed.
