Vulcan Cyber alternatives that stay scanner-independent
Vulcan Cyber is now part of Tenable. If you chose Vulcan to manage findings from many different scanners, DefectDojo Pro does that job across 500+ tools, as SaaS or self-hosted.
What are the best alternatives to Vulcan Cyber?
Tenable acquired Vulcan Cyber in February 2025 and is folding it into Tenable One, and vulcan.io now redirects to Tenable. Teams that chose Vulcan to stay independent of any one scanner usually compare other scanner-independent platforms: DefectDojo Pro, Nucleus Security, Brinqa, ArmorCode and Seemplicity. Teams standardizing on Tenable scanners can move to Tenable One.

Moving off Vulcan Cyber
List your sources
Note every scanner and connector feeding Vulcan today.
Connect them to DefectDojo
There is no direct Vulcan import, so connect each scanner to DefectDojo directly. Most have a parser or a connector already.
Rebuild routing and SLAs
Recreate ticket routing and remediation SLAs per asset or organization.
Run side by side
Keep both running until the backlogs match, then switch over.
Why scanner independence matters now
Vulcan Cyber, Kenna Security and other independent platforms have been bought or retired in the past two years. DefectDojo's open source core, available since 2015 under the BSD-3-Clause license, means your vulnerability data and workflows don't depend on one vendor's roadmap.
