Want one of these looked at properly?
This scan is broad and passive — it reads what your site shows everyone, across all five areas. A deep audit takes one of those areas and goes all the way down on your site specifically.
No email, no sign-up. Pick the one you care about.
Watch this site's security
We'll email you if its security slips: a new vulnerability, an expiring certificate, a blacklisting. No account needed.
Security alerts only. Nothing else, and no email unless something is wrong. Unsubscribe anytime.

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.
