Please note that the Application Team does their best to capture the Windows Insider Builds for our clients' convenience. However, due to the updating frequency of the Insider Builds, they are not considered fully supported by ThreatLocker.

The ThreatLocker Agent is installed locally on each endpoint, but it is not resource heavy. Generally speaking, you can expect to see less than 1% CPU usage and 200-600 MB of RAM.
