OSWA
OffSec Web Assessor · OffSec
The OSWA validates black-box web application testing: discovering and exploiting cross-site scripting, injections, server-side request forgery, template injection and other common flaws, in a fully practical exam. It is less famous than the OSWE but fills a gap for web testers who do not have access to the source code. Its strength is a realistic, hands-on exam; its limit is that it is still little known to recruiters and does not cover code review.
