 ## DAST On-Demand Scans
 
 If you don’t want scans running in your normal DevOps process you can use on-demand scans instead. For more details, see [on-demand scans](dast/index.md#on-demand-scans). This feature is only available for DAST. If you run an on-demand scan against the default branch, it is reported as a "successful pipeline" and these results are included in the security dashboard and vulnerability report.
