For the existence of sensitive data on the site, how to does Acunetix use the command line to exclude or not use the form to fill the function?

It can be set by setting as follows:

We recommend that you first scan the test environment thoroughly.

However, if you want to exclude scanning a particular page or table, you can set the directory and file filter implementation

The path is: Configuration> Scan Settings> Crawling Options> Directory and File Filters

Make sure you click the "Apply" button so that the changes can take effect.

You can save these settings as a new template and then use this new template to scan through the command line.
