Accessible instantly for free, no enterprise contract, no complex setup required. Qualys is a solid Enterprise Vulnerability Scanner, but its pricing ($2,500+/year) puts it out of reach for individual developers and small teams who just need a reliable external vulnerability scan.
VulnScan scans your site from outside your network — the same vantage point as attackers. This black-box approach finds exposed subdomains, open ports, misconfigured servers, and externally visible CVEs that internal tools often miss.
Free external vulnerability scan. 60 seconds. Zero signup.
