Grade any site's HTTP security headers in one call — HSTS, CSP, X-Frame-Options and more, with an A–F grade and what's missing. No API key, pay per URL.

▶ Live on the Apify Store: https://apify.com/eliai/security-headers-checker — run it instantly, or call it as an agent tool via Apify MCP.

What it checks

  • Strict-Transport-Security (HSTS) — forces HTTPS
  • Content-Security-Policy — mitigates XSS/injection
  • X-Frame-Options — prevents clickjacking
  • X-Content-Type-Options — stops MIME sniffing
  • Referrer-Policy — controls referrer leakage
  • Permissions-Policy — restricts powerful browser features

Returns an A–F grade + score, the headers present (with values), and the missing ones with why each matters.

Input

{"url":"https://example.com"}

or bulk:

{"urls":["https://a.com","https://b.com"],"maxUrls":25}

Output (per URL)

{
"url":"https://example.com",
"grade":"B",
"securityScore":66,
"present":[{"header":"Strict-Transport-Security (HSTS)","value":"max-age=31536000"}],
"missing":[{"header":"Content-Security-Policy","why":"Mitigates XSS and content-injection"}],
"summary":"B (66/100) — 2 missing"
}

Use cases

Security audits, compliance checks, and pre-launch hardening — by hand or wired into a CI/agent pipeline. Pairs with our SEO & Tech Auditor and Broken Link Checker.
