ThreatLocker, founded in 2017, is a cybersecurity firm headquartered in Orlando, Florida, with an additional office in Dublin, Ireland. The company develops a Zero Trust endpoint protection platform that applies a default-deny security model to enterprise environments. Its approach marks a deliberate shift away from reactive, detection-based security toward proactive prevention.
The ThreatLocker platform encompasses a range of security capabilities: application allowlisting, ringfencing, storage control, elevation control, zero trust network access, zero trust cloud access, patch management, and managed detection and response. These features are delivered as an integrated suite rather than standalone tools, giving organisations centralised control over endpoint activity.
The company serves thousands of organisations globally, including Heathrow Airport, JetBlue, the US Navy, and the Indianapolis Colts. It has achieved FedRAMP Authorization, enabling it to meet the compliance requirements of US government customers. ThreatLocker also hosts the annual Zero Trust World conference, reflecting its focus on the Zero Trust security framework.
