Administrators need to confirm why a URL is isolated or not isolated.

Email Threat Isolation

The URL isolation feature assesses URL risk levels to determine whether a URL is isolated.

• URL Risk 1-3: URLs that come from trusted and reputable sources, with top-ranked sites and safe web traffic.
• URL Risk 4-7: URLs that are very new or lack safe history, or those that show some suspicious behavior.
• URL Risk 8-9: URLs with suspicious behavior, and some evidence of malicious activity.
• URL Risk 10: URLs with strong evidence of malicious activity.

For URL risk levels 1-3, end users are redirected to the destination URLs as normal, with no isolation action.

For URL risk levels 4-7, all links are isolated with an option for the end user to break out of the isolation.

For URL risk levels 8-10, all links are isolated, and there is no option to break out of the isolation.

By downloading URL Isolation Incidents Report, the risk level of the URL can be confirmed.
