VIPRE Recommends

Your experience with Link Isolation is dependent on the options you choose here. Review all of the options below carefully to determine the best action plan for your organization before implementation.

The scanning and analysis processes for Link Isolation can take up to approximately 20-30 seconds. During that time, important steps are taking place - some of these steps include loading the URL into the cloud browser, waiting for all embedded scripts to execute fully, and putting the page through a series of tests. 

You can fine-tune the system by ensuring all sites/domains that are used frequently by your organization and are known to be safe have been added to the Allowed IPs/Domains tab.

 

 

URL Filter Configuration

  1. On the URL Filter Configuration tab, select from the following options:
    • Click-time Protection
      • Enable Deeplink: This option allows Link Isolation to perform deep, cloud-based scanning in order to analyze malicious URLs and obtain more information;  ; also enables URL categorization and screenshots/previews of malicious URLs
      • Click-Through > Block: Blocks all potentially malicious URLs that have been clicked in the email; unable to proceed
      • Click-Through > Warn and allow override: Displays a warning when potentially malicious URLs have been clicked in the email; gives the option to ignore the warning and proceed to the website
    • URL Rewriting
      • Exclude my own domains: URLs containing any of the domains you've added to your account will not be rewritten
      • Rewrite displayed URLs and underlying links: Visible links shown as URLs will be rewritten; this may alter the appearance of the email as rewritten URLs can be quite long
      • Rewrite URLs in text mode email: Rewrites URLs both in HTML and text mode; this may alter the appearance of the email as rewritten URLs can be quite long
  2. Click Save

 

 

 
 

Allowed IPs/Domains

    2. When attempting to access an IP address or domain that has been denied
  2. Click Save
