If an end user clicks on a malicious URL rewritten by an Outbreak Filter or Policy (using Content or 
Message Filters), the Cisco Web Security proxy displays a Cisco branded notification page to the end 
user in the web browser. This page notifies that the site is malicious and access to it has been blocked. 
You can customize the appearance of this notification page and display your organization's branding 
such as company logo, contact information, and so on. See

Keep in mind that, when an end user clicks on a URL rewritten using Outbreak Filter, the notification 
page is displayed for 10 seconds and then redirected to the to the Cisco Web Security proxy (Cisco 
branded) for click-time evaluation.
