On the "Sites" page, the site tree shows all of the sites that you have created in Burp Suite Enterprise Edition. However, as your list of sites begins to grow, it is a good idea to organize your site tree using folders and subfolders. For example, you could organize your sites based on their geographic location. However, any hierarchical structure is possible.
Folders also have their own dashboards, so you can view filtered metrics for all sites in a specific folder.
You can even use folders to restrict access, so users are only able to access data for sites that are relevant to them.
On the "Sites" page, in the upper-right corner, click the "New folder" button. A blank folder appears in the list.
Enter a name for the folder and press enter. If you hover the mouse over the folder, notice that several small icons appear on the right of the screen. These are for creating a new site, creating a new subfolder, and deleting the current folder.
If you click on a folder, you will see metrics, scans, and issues for all sites in this folder. Exactly what is shown depends on whether you have completed any scans.
Once you have created a folder, you can add sites to it to group them. You can create new sites for a folder in a couple of different ways:
To add an existing site to a folder, open the site, go to the "Details" tab, and click "Select folder".
Note that site names must be unique within a given folder.
