Ransomware detection and blocking

Advanced ransomware quickly encrypts systems. Email, a prevalent attack vector, needs blocking before delivery. Trend Micro™ Deep Discovery™ Email Inspector effectively detects and blocks ransomware spear phishing emails using advanced analysis for known and unknown attacks. Custom sandboxing identifies mass file changes, encryption behavior, and backup process alterations.

Powerful detection expand_more

Extensive detection techniques

Deep Discovery Email Inspector ensures high detection and low false positives:

  • Web filtering and URL time-of-click analysis
  • Malware identification via machine learning
  • Custom sandbox, anti-evasion tech, behavioral analysis, ML-based C&C
  • Spam, content filtering, Trend Micro™ Data Loss Prevention™
  • Supports Mitre ATT&CK framework for effective threat detection and response
Custom sandboxing expand_more

Identify and enhance detection capabilities

Custom sandboxes use virtual images to match system configurations, drivers, applications, and languages. Difficult to evade, they include a “safe live mode” to analyse downloads, URLs, C&C, and more. They identify ransomware, encryption, backup modification, and encryption. Deep Discovery Email Inspector uses machine learning inside the sandbox to enhance detection.

Complete security expand_more

Optimised and connected

  • Centralized visibility and control delivered through Trend Micro Control Manager with prioritized alerting by severity or host
  • Threat sharing with Trend Micro and other in-place security investments
  • Integration with SIEMs, like HP Arcsight, IBM QRadar, and Splunk
Reduced costs expand_more

Optimise incident response

Dramatically reduce the time required to remediate and prevent targeted ransomware attacks. A single appliance that blocks suspicious email and shares threat information, it also provides sandboxing to optimise incident response.

Virtual appliance deployment

For additional flexibility, Deep Discovery Email Inspector can be deployed as a virtual server on your own virtual environment when connected to Trend Micro™ Deep Discovery™ Analyser hardware appliances. In this deployment scenario, the virtual appliance will provide all functions except for sandbox analysis, which is done on Analyser appliances.


  • Supports VMware ESXi 6.0 or 6.5 and Microsoft Hyper-V on Windows Server 2016 or 2019
  • Deep Discovery Analyser hardware appliance(s) are required for sandbox analysis

Optional spam gateway filtering

Enable Deep Discovery Email Inspector to filter inbound messages based on senders, spam and phishing filters, and content, while providing outbound Trend Micro™ Data Loss Prevention™ and email encryption. Includes end user quarantine for spam messages, and content disarm and reconstruction (CDR) to remove executable objects from Microsoft files.

Market-leading performance

Achieved Advanced Threat Defence certification in independent testing from ICSA labs
