This scan is passive. An attacker won't be.
The free scan reads what your site shows everyone. A Deep Audit does what an attacker does — it actively probes your verified site for what's really exposed.
This free scan (passive)
- Security score
- Known-CVE counts
- Security headers
- TLS & certificate
- Blacklist & Safe Browsing
Deep Audit — active scan of your verified site
- Per-CVE breakdown: IDs, severity, exploit availability, fix version
- Exposed files (.git, .env, backups)
- Directory listing
- Open admin panels
- Open ports
- Subdomain exposure
- Prioritized fix plan
- Full PDF report
What we can't check without your permission
These need active probing of your site: exposed .git/.env/backups, open admin panels, open ports, forgotten subdomains. Verify your domain and we'll show you what an attacker would find.
How it works
- Verify your domain — a file or DNS record, about 2 minutes.
- We actively scan it — a few minutes; we email you when it's ready.
- Get your full report + PDF.
The deep scan is live and free while we're in beta. Verify your domain and run it now.
Active checks run only on a domain you've verified as yours, with your consent. We detect — never exploit. Free in beta; $39 one-time after launch, no subscription — and early adopters keep the deep scan free.
