Deep Discovery Email Inspector assesses email message risk using multi-layered threat analysis. Upon receiving an email message, Deep Discovery Email Inspector email scanners check the email message for known threats in the Trend Micro Smart Protection Network and Trend Micro Advanced Threat Scanning Engine. If the email message has unknown or suspicious characteristics, the email scanners send file attachments and embedded URLs to Virtual Analyzer for further analysis. Virtual Analyzer simulates the suspicious file and URL behavior to identify potential threats. Deep Discovery Email Inspector assigns a risk level to the email message based on the highest risk assigned between the Deep Discovery Email Inspector scanners and Virtual Analyzer.
