Security Technology Monitors

You are responsible for management and routine monitoring of the Managed Defense Supported Technology, and any intermediate systems that support communication with Managed Defense. This includes being responsible for identifying and taking all actions needed to bring devices online in the event of an outage and applying updates and patches. Since your security technologies must be in a good state of health for Managed Defense to provide our services, we provide a set of monitors to assist you with this monitoring. The following table lists the available monitors for customer-managed Trellix Supported Technologies.
