We scan 10 security dimensions: exposed secrets & API keys, HTTP security headers, SSL/TLS certificates, cookie security flags, mixed content, CORS misconfigurations, known dependency CVEs, client-side auth bypasses, exposed sensitive paths (/.env, /.git, /admin), and basic SEO meta tags.
No. Your first scan is completely anonymous — just paste a URL and get your security grade in under 60 seconds. You only need an account if you want to track scan history or set up recurring monitoring.
Manual reviews take 24+ hours and cost $19–$29. ShieldStack gives you instant results for free by scanning your live site automatically. We catch the most common vulnerabilities in AI-generated code within seconds, not days.
The free scan shows your score, grade, and finding titles. After scanning, you can optionally unlock the Pro Report for detailed descriptions of each vulnerability, step-by-step fix recommendations with code snippets, affected file paths, and a downloadable PDF you can share with your team.
We store minimal scan metadata (URL, score, findings) to display your results. We never store your source code or page content. Scan data is automatically purged after 90 days for anonymous scans.
