Ringfencing™ controls what applications are able to do once they are running. By limiting what software can do, ThreatLocker® can reduce the likelihood of an exploit being successful or an attacker weaponizing legitimate tools such as PowerShell. Ringfencing™ allows you to control how applications can interact with other applications. For example, while both Microsoft Word and PowerShell may be permitted, Ringfencing™ will stop Microsoft Word from being able to call PowerShell, thus preventing an attempted exploit of a vulnerability such as the Follina vulnerability from being successful.
