Trend Micro web reputation technology helps break the infection chain by assigning websites a "reputation" based on an assessment of the trustworthiness of a URL, derived from an analysis of the domain. Web reputation protects against web-based threats including zero-day attacks, before they reach the network. Trend Micro web reputation technology tracks the lifecycle of hundreds of millions of web domains, extending proven Trend Micro anti-spam protection to the Internet.
The Web reputation criteria are configured to prevent access to malicious URLs in email messages.
Hosted Email Security does not apply content-based heuristic spam, BEC, phishing, graymail, Web reputation, or social engineering attack rules to email messages received from email addresses and domains listed on the Approved Senders screen.
