Aug 13, 2025 — Enhanced Error Response Page

When users attempt to access a domain that ​SIA​ determines is a known or suspected risk to your organization, a new error page for Risky Domains appears. Risky domains are domains that belong to these threat categories: Adware, Coin Mining, Newly Registered, Newly Seen, Potentially Harmful, and DNS Tunneling. To learn more about these categories, see Threat categories.

This new error page indicates that the request to the risky domain was blocked and advises users to reach out to their administrator or IT department for more information. To learn more about this error page, see Threat website warning.
