Subdomain Takeover Scanner
20 service fingerprints (GitHub, Heroku, S3, etc.). Part of AuditCore's automated security audit pipeline — runs on every scan in the Pro tier and above, with findings normalized into a single severity-rated table.
What is Subdomain Takeover Scanner?
Subdomain Takeover Scanner runs in the Reconnaissance phase of every AuditCore scan that includes it. Discover the target attack surface — subdomains, live hosts, hidden directories, mail config — before any active probing.
Out of the box it covers: 20 service fingerprints (GitHub, Heroku, S3, etc.). Findings are normalized into AuditCore's vulnerability model so they appear next to results from every other scanner — no separate tabs, no tool-specific jargon, one CVSS-rated table.
If you've ever wondered which scanners actually run when you click "Start scan" on AuditCore, this is one of them. The full pipeline is documented per phase, and you can see exactly which tools fired on any given scan from the live terminal feed.
