AgentMinds vs SecurityHeaders.com
SecurityHeaders.com is the canonical security headers checker — and we run essentially the same checks. Here's the difference, fairly.
What SecurityHeaders.com does well
Scott Helme's securityheaders.com is a single-purpose tool that nailed security headers grading before most people knew what HSTS or CSP were. The grading rubric is widely cited, the embeddable badge is everywhere, and the API is simple. If your only question is "what's wrong with my Content-Security-Policy?", you don't need anything else.
What AgentMinds adds
We check the same headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, CORP, COEP, X-XSS-Protection — all 10 of the canonical list), but the scan continues past security:
- SEO + AEO audit (50+ checks beyond headers)
- Performance metrics (latency, content size)
- Cross-site pattern matching — "73 other sites solved this CSP issue with X"
- Personalized recommendations re-ranked for your stack and site type
- Continuous monitoring (every 6h) with email alerts on regressions

Use SecurityHeaders.com when
- You only need security headers — nothing more
- You want the canonical reference grade (it's the de facto standard)
- You're reviewing a long list of domains via API and don't need fix recommendations
Use AgentMinds when
- You want security + SEO + AEO + performance in one scan
- You want to know how to fix issues, with patterns from real production sites
- You want continuous monitoring with alerts, not one-off scans
- You want shareable scan URLs and embeddable badges (we have both)
We respect the work that went into SecurityHeaders.com — the grading rubric we use for the security portion is directly inspired by Scott's. AgentMinds is a broader audit that treats security as one of five dimensions, not the only one.
