Finished my OSCP without Dradis. Used Freemind + yed + keepnote + OpenOffice für documentation.
Looking back I would say it would waste way too much time to implement a workflow from dradis import to OSCP report.
(That is, if you cannot find an existing oscp dradis template).
OSCP expects the report as PDF. They provide an odt / docx template. I guess it would be a good marketing strategy for dradis to create an OSCP template.
I used my own tool to merge all nmap scans. As I am using the pro version of Dradis now, I would still keep with my tool. Although it is helpfull to import nmap scans and generate the tables for an office document… this can also be achieved with magictree.
I guess the greatest advantage of dradis pro would be the issueLibrary, where you can write a vulnerability description once and reuse it again and again. In the OSCP however, you are going to meet different vulnerabilities on each system.
Keep in mind: Whatever tool you use, in the exam you won’t have time for bugsearch in your reporting tool. Find the tool you can work best with. Test it during the lab time. And if you write your own scripts for recon, consider using an json/xml output. It will allow you to import it to other tools easier.
