As of 2.6+ you can create a new scanner source in order to import vulnerability reports from other 3rd parties or non-natively supported scanning tools. These require the use of the .ThreadFix file format in order to import, but you must create the scanner identifier in Threadfix first.
Creating a Scanner
- Go to Settings
- Select Scanner Settings → Create Scanner
- Complete necessary details and click "Create Scanner"
- Although the new scanner will appear to not be allowed for import, logging out and back in to ThreadFix will reflect that it is, in fact, allowed.
