VIPRE Link Isolation

VIPRE Email Security Link Isolation is like URL sandboxing for your email. When a user clicks on a URL within an email, the email is then scanned again and Link Isolation analyzes the URL. Rescanning the link at the time the user clicks on it, even if it happens days or months after receiving the email, provides stronger protection against zero-day threats.


An email comes in that contains a link and your employee clicks on the link.

  1. VIPRE receives the URL analysis request
  2. The link analysis service then simulates a session using the same browser and client type as the requestor
  3. During the simulation, VIPRE investigates the behavior of the site and:
    1. Analyzes the site's behavior
    2. Provides the analysis results, determining whether the site is malicious, suspicious, or unknown and classification
    3. Collects screenshot of the website's appearance, features, and a "sanitized", safe version of the site that can be replayed in the user's browser
  4. If the URL is deemed suspicious, the user sees a message indicating restricted access to the site with either a warning message before proceeding or a complete block

Important Information

The scanning process for Link Isolation takes approximately seven seconds. During that time, important steps are taking place - the URL is being loaded into the cloud browser (see What to Expect section below), waiting for all embedded scripts to fully execute, and putting the page through a series of tests. 

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

Refer to Related Articles for details on how to configure Link Isolation.

What to Expect

After Link Isolation is enabled, when an end user clicks a URL within an email, they will experience the following based on the Click through action chosen on the URL Filter Configuration tab and any customizations made to the templates (see Step 3 - Templates above):

Warn and Allow Block


If you have chosen the click-through action of "Warn and Allow" then you'll see a page similar to this.


If you have chosen the click-through action of "Block" then you'll see a page similar to this.


At the bottom of the page, you'll see a small screenshot of the URL in question with options to: 
  • See a safe, stripped-down, version of the page
  • To continue on to the whole site, accepting the risk
  • Report an error if this is a known clean and safe site
