About VulnScan

VulnScan is a free online vulnerability scanner built by security researchers and penetration testers who were frustrated with the state of website security tooling.

Our Mission

Enterprise-grade vulnerability scanning costs thousands of dollars per year. Small businesses, indie developers, and startups are left running their websites with zero visibility into their security posture — until they get hacked.

VulnScan exists to fix that. We give every website owner access to the same external scanning capability that enterprise security teams use, completely free. No signup, no credit card, no 30-day trial. Just enter your domain and get your security grade in minutes.
