Free scanners check one thing.
We check everything.
SSL Labs, Mozilla Observatory and securityheaders.com are great at their one job. BoringSec coordinates 20 URL base modules and 3 verified-owner background engines — and keeps watching.
Categories covered in one scan
One BoringSec scan replaces all three free tools — and covers the categories they can't see.
Paste a website URL or GitHub repo link, and we auto-detect which scan to run.
What each scanner actually checks
An honest comparison against SSL Labs, Mozilla Observatory, securityheaders.com. Where free tools are strong, we say so — the difference is how much one BoringSec scan covers.

Four things a one-shot scanner can’t do
One workflow, independent modules
Headers, TLS, DNS, cookies, CORS, exposure, injection, XSS, subdomains, secrets, databases, technology CVEs, privacy, reputation and more — aggregated into a single A++ to F grade instead of three separate tools you have to run and reconcile yourself.
- 20 base modules in one workflow
- One unified score & report
- 3 verified-owner background engines
Catches what header-checkers can’t
Free scanners read your response headers. BoringSec reads your shipped JavaScript and infrastructure — finding exposed Stripe, AWS, Supabase and GitHub keys, open Supabase RLS and Firebase rules, and known CVEs in the libraries you actually use.
- Leaked API keys in your bundles
- Open database rules (RLS / Firebase)
- CVEs matched via the OSV database
Security isn’t a one-time check
A clean scan today says nothing about next week. BoringSec keeps watching — re-scanning on a schedule and alerting you to certificate expiry, defacement, new vulnerabilities, blacklisting and downtime.
- Scheduled re-scans from $19/mo
- Certificate-expiry countdown
- Defacement & blacklist alerts
Fix it, don’t just find it
Every finding comes with a plain-language explanation, the exact evidence we observed, and a fix you can act on — including AI-ready fix prompts. And the whole report renders in the language of the site you scanned.
- Plain-language remediation
- Copy-paste AI fix prompts
- Localized in 10 languages
Why free scanners aren’t enough
They’re excellent spot-checks for a single dimension. They were never meant to be your whole security picture.
We genuinely like SSL Labs, Mozilla Observatory, securityheaders.com — we use them too. They do their one job well, and this isn’t about replacing a good TLS or header check. It’s about everything those checks can’t see. BoringSec gives you the complete picture in one place.
