Security Warnings

  • Last updated on

When Email Gateway Defense determines an embedded web link is fraudulent or inappropriate, a security warning displays onscreen with the available actions.

Blocked Categories

Blocked content categories include:

  • Hacking
  • Phishing Attacks
  • Spam
  • Typosqatting
  • Spyware
  • Malicious Sites

When a link containing a blocked content category is detected, a Security Warning displays. For example:


If a typosquatted link is detected in a user's email, the Security Warning page displays the fraudulent or inappropriate link (which cannot be clicked) and supplies a verified link to the valid domain.

Learn to Detect and Prevent Future Attacks

There are short, end-user training exercises integrated into the Security Warnings to help users understand what they did wrong and teach them how to identify threats in the future.
