As a long time user of the IMSS solution, sadly it was time to move on. **Rating:** 3.0/5.0 stars **Reviewed by:** Gregory D. | Cybersecurity, Compliance and Data Protection Officer, Electrical/Electronic Manufacturing, Mid-Market (51-1000 emp.) **Reviewed Date:** August 28, 2022 **What do you like best about InterScan Messaging Security?** IMSS excels at the basic protection that it is designed to provide, i.e. antivirus and antispam. It is fairly easy to use and very granular. Rules management is done via a web console. The level of granularity is excellent, meaning it is possible to customise the rules at a deep granular level, perfect for admins who want a deep level of control of the email gateway and security features. **What do you dislike about InterScan Messaging Security?** Sadly, IMSS has been falling behind the competition as of late, when it comes to the new types of threats (e.g. BEC) and modern protection measures needed to counter them (e.g. sandboxing, DLP, ...) The lack of updates and new features in the last couple of years makes me wonder if Trend Micro is still maintaining this product. **What problems is InterScan Messaging Security solving and how is that benefiting you?** IMSS was used as the primary secure email gateway (SEG) platform at our company for the best part of 15 years. It secures the corporate email server by filtering out spam, phishing, viruses, malware, and also features a keywords filter. ## InterScan Messaging Security Discussions - [What is InterScan Messaging Security used for?](https://www.g2.com/discussions/what-is-interscan-messaging-security-used-for) - [View InterScan Messaging Security pricing details and edition comparison](https://www.g2.com/products/interscan-messaging-security/reviews?filters%5Bnps_score%5D%5B%5D=3§ion=pricing&secure%5Bexpires_at%5D=2026-08-12+16%3A24%3A16+-0500&secure%5Bsession_id%5D=8126fcbe-d716-4907-bc26-82fc85aa2a66&secure%5Btoken%5D=64cad99d95d2bc1fbe9cf90fba8cbcbfca25a873e6fca7e2783aa9ba50641810&format=llm_user) ## InterScan Messaging Security Features **Additional Functionality** - Phishing Protection - Threat Response - Domain Check - Security Auditing - AI/Machine Learning - Third-Party Integrations - AI Copilot - Reporting/Analytics - Anomaly/Malware Detection - SURLB/URIBL Filtering - Activity Dashboard - Scheduled/Automated Reports - For MSPs - Whitelisting/Blacklisting - Fraud Detection - Spam Blocker - Spam Quarantine - API - Data Leak Prevention - Encryption - Audit Trail - Real-Time Monitoring - Spam Analysis - Policy Management - Alerts/Escalation - Email Management - Vulnerability Scanning - Generative AI - Threat Protection - Email Attachment Protection - Email Filtering - Two-Factor Authentication **Administration** - Compliance - Intelligence Reporting - Email Clients - Role-Based Rules **Agentic AI - Email Anti-spam Features** - Autonomous Task Execution - Proactive Assistance **Additional Functionality** - Phishing Protection - Data Recovery - Archiving & Retention - Backup and Recovery - Policy Management - Email Management - Data Loss Prevention - Single Sign On - Data Storage Management - Fraud Detection - Email Routing - Data Verification - Compliance Management - Filtering - Search/Filter - SURLB/URIBL Filtering - Security Auditing - Data Synchronization - Anti Virus - Risk Assessment - Greylisting - Audit Trail - Reporting/Analytics - Allow/Block List - Vulnerability Scanning - Active Directory Integration - Compression - Email Tracking - Encryption - Anti Spam - Disaster Recovery - AI Copilot - Tagging - Secure Data Storage - Activity Tracking - Spam Blocker - Microsoft Outlook Integration - Spam Analysis - API - Categorization/Grouping - Event Tracking - Inbox Management - Spam Detection - Authentication - Third-Party Integrations - Reporting & Statistics - Spam Quarantine - SSL Security - Generative AI - Data Retention Management - Access Controls/Permissions - Monitoring **Detection** - Data Exfiltration Detection - Activity Monitoring - Real-Time Detection **Protection** - Targeted Attack Prevention - Policy Enforcement - Spam Filtering **Agentic AI - Intelligent Email Protection** - Autonomous Task Execution - Adaptive Learning ## Top InterScan Messaging Security Alternatives - [Proofpoint Core Email Protection](https://www.g2.com/products/proofpoint-core-email-protection/reviews) - 4.6/5.0 (589 reviews) - [Check Point Email Security](https://www.g2.com/products/check-point-email-security/reviews) - 4.6/5.0 (487 reviews) - [Validity Engage](https://www.g2.com/products/validity-engage/reviews) - 4.5/5.0 (973 reviews)
