What is HTTPS & HSTS?
HTTPS encrypts traffic. HSTS forces browsers to use HTTPS for your domain, preventing downgrade and cookie leakage over HTTP.
What this checker validates
- HTTPS redirect chain and mixed HTTP hops
- HSTS max-age, includeSubDomains, preload token
- Preload list readiness criteria
How to fix common failures
- Redirect HTTP to HTTPS at the edge (single hop)
- Set max-age ≥ 31536000, and add includeSubDomains and preload
- Verify subdomains are HTTPS‑ready before preloading
Tool-specific questions
What max-age for preload?
Is HSTS risky?
Do I need both www and apex?
How do I become HSTS preload-ready?
