The New and Unknown Threats widget on the Symantec Advanced Threat Protection (ATP) Dashboard in ATP Manager lists the number of files that were detected as threats within your environment by the following Symantec technologies:
Detects unknown malware and advanced threats from the files that are executed in a virtual sandbox and then compared to real-world data in the Symantec Global Intelligence Network
Detects files with bad reputations using Symantec's cloud-based reputation database
The outer arc in the widget represents the total number of detected threats. Each inner arc represents a specific technology (Sandbox or Insight). The size of the arc represents the percentage of threats that were detected by that technology. You can hover over an arc to display the number of threats that were detected by that technology. You can click on an arc to navigate to the Search page to view the conviction events that are associated with that technology.
