What is Ringfencing™?

This document explains ThreatLocker Ringfencing, a Zero Trust application containment tool that enforces granular policies to restrict how applications interact with files, other apps, and the internet, thereby reducing attack surface, limiting lateral movement, enhancing detection and response, and supporting compliance and operational stability. It promotes using Ringfencing alongside allowlisting as a layered defense and references the 2021 Kaseya/REvil incident to illustrate its protective value.
