How do I view the vulnerability trend for an asset?

You can easily view the trend chart for an asset by following these steps: 

1. Log in to Security Center.
2. Click on Asset Manager.  
   In this window, all your added network assets will show.
3. Click on Web Applications to show all your added web application assets.
4. Click on this symbol  to the right of the asset. 
5. Click on Trends.

Now you will see a trend chart of the vulnerabilities over time for the selected asset.

Here you can check/uncheck the boxes for severity and choose which period and interval to customize how you view the trend chart.

A quick and easy way to hide or show the curves is to click on the severity name below the chart.
