Most Trellix IPS customers begin their deployment in their lab environment. Here they test the Sensor functionality, familiarize themselves with the Manager, and create an initial policy. Once they are comfortable with the product, they deploy the Sensor in a live environment.
Trellix provides a few recommendations for this process:
Spend time creating effective policies before actual deployment. Availability of more information makes the tuning process easier. But policies, such as the Trellix IPS provided All-Inclusive policy, can overwhelm you with data, if every Sensor in a large deployment is running it without any customization.
Stagger your Sensor deployment in phases. As each new batch of Sensors provides you with more data points, you can tune your policies more effectively, and become more proactive with the number of Sensors you deploy in the next phase.
