ThreatLocker Ringfencing for Application Containment
Summary
Hide ▲
Show ▼
ThreatLocker Ringfencing™ is an advanced containment strategy for applications already approved to run. It enforces the principle of least privilege by restricting what authorized applications can access, including files, registry keys, network resources, and other processes. This granular control mitigates risks associated with legitimate software being weaponized by threat actors, such as lateral movement, data exfiltration, and ransomware encryption. Ringfencing supports compliance goals and enhances operational efficiency by reducing SOC alerts and minimizing user friction.
