The best settings to configure the Machine Learning levels of the Prevention Policy so it does not interfere with existing solutions during the testing phase are Cautious for both Detection and Prevention sliders. This setting will enable the sensor to detect and prevent only high-confidence malicious events, while allowing low-confidence events to run without interference. This setting will also generate less noise and false positives than higher settings, such as Moderate or Extra Aggressive1.
