Exclusions

It is recommended to create exclusions before the first deployment - through the planning phase. Exclusions can also be created through the first deployment phase on the Test/POC group of assets.

During the learning mode phase notice the following for exclusions:

Internally trusted processes or certified applications that create FPs or load.
Do not exclude the OS (Microsoft/Apple) certificate
Internally trusted and protected domains

How to exclude?

This solution has been verified for the specific scenario, described by the combination of Product, Version and Symptoms. It may not work in other scenarios.
