Security Headers
Grade your site on the HTTP headers that stop common attacks.
Security Headers, created by Scott Helme, scans any site and grades its HTTP response headers: CSP, HSTS, frame options and friends. It is free and the fastest way to spot missing browser-level protections.
Best for: Use this when you want a one-minute check that your site sends the protective headers it should.
Pros
- Instant scan with a clear letter grade
- Explains what each missing header would protect against
- Free with no account
Cons
- Headers are one layer, a good grade is not a security audit
- CSP quality is hard to judge from presence alone
