If you enable Time-of-Click Protection when creating a spam policy, Trend Micro Email Security rewrites URLs in email messages for further analysis. Trend Micro analyzes those URLs at the time of click, and will block access to them or show a warning page (depending on your settings) if they are malicious.
You can choose to use the default blocking and warning pages or customize the blocking and warning pages according to your preference.
Dangerous: Select an action (Allow, Warn or Block) to take on dangerous URLs. The default value is Block.
Dangerous URLs are verified to be fraudulent or known sources of threats.
Highly Suspicious: Select an action (Allow, Warn or Block) to take on highly suspicious URLs. The default value is Block.
Highly suspicious URLs are suspected to be fraudulent or possible sources of threats.
Suspicious: Select an action (Allow, Warn or Block) to take on suspicious URLs. The default value is Warn.
Suspicious URLs are associated with spam or possibly compromised.
Untested: Select an action (Allow, Warn or Block) to take on untested URLs. The default value is Warn.
While Trend Micro actively tests URLs for safety, users may encounter untested pages when visiting new or less popular websites. Blocking access to untested pages can improve safety but can also prevent access to safe pages.
Use default redirect pages: The default blocking page or warning page will appear when a malicious URL in the email message is clicked.
Customize redirect pages: Customize your own blocking page and warning page if you do not want to use the default ones.
Type a title for Browser Tab Title.
Next to Content, click the icon next to the strings on the Dangerous tab and customize the strings.
Repeat the customization settings on the Highly Suspicious, Suspicious, and Untested tabs in sequence.
Type the click-through link text.
The click-through link text you customize apply to the warning pages for malicious URLs at each of the preceding risk levels.
The click-through link appears on the warning page only.
