Ringfencing by ThreatLocker enhances cybersecurity by controlling application interactions and limiting access to sensitive data, thus reducing the risk of cyberattacks, including those using fileless malware. It allows organizations to create tailored security policies for applications, ensuring that only necessary permissions are granted and preventing potential exploits. The service is designed to support a wide range of applications, providing a robust defense against unauthorized access and data breaches.

A ransomware attack targeting a hospital was thwarted by ThreatLocker, which utilized application allowlisting and storage control to prevent unauthorized software from running and protect sensitive data. The cybercriminals, frustrated by the security measures, were unable to deploy their tools or execute their plan. This incident highlights how ThreatLocker effectively defends against such cyber threats.
