What is Trend Micro?
Trend Micro Site Safety Center is the web reputation system powering Trend Micro Internet Security, Maximum Security, Worry-Free Business Security, and enterprise Deep Security products. It evaluates URLs against behavioral analysis, historical reputation, and threat intelligence to assign safety ratings. Trend Micro protects over 500,000 businesses and millions of consumers across 65+ countries, with particularly strong market share in Japan and Asia-Pacific.
Why Trend Micro flags legitimate domains
- Trend Micro web crawlers detected malicious code, exploit kits, or drive-by download behavior
- Your domain appeared in spam campaigns tracked by Trend Micro Smart Protection Network
- Behavioral heuristics flagged suspicious patterns (obfuscation, redirect chains, popup abuse)
- Your site loads resources from domains already in Trend Micro's threat database
- Your SSL certificate chain is incomplete or misconfigured, triggering security warnings
- Previous compromise was remediated but Trend Micro still holds the outdated dangerous rating
What a listing means for your business
A Trend Micro "Dangerous" rating triggers full-page block warnings across all Trend Micro consumer and enterprise products. With dominant market share in Japan and APAC, this disproportionately blocks traffic from Asian enterprise users. Trend Micro also provides web reputation data to third-party products, extending the impact beyond their own user base.
