Why does HSTS matter?

HSTS tells browsers to always connect over HTTPS, preventing downgrade and first-request attacks once a user has visited.

A read-only probe checks that http:// redirects to https and that https responses include a long-lived HSTS header.

Redirect all HTTP to HTTPS with a 301 at the host or CDN and send a long-lived HSTS header on HTTPS responses.

HTTPS & HSTS Check — Does Your Site Force Secure Connections?

DevMeth checks the 48 known AI-code failure patterns — not a penetration test or a security guarantee.

What the issue is

A site that does not redirect HTTP to HTTPS, or that omits a long-lived HSTS header, lets traffic run in the clear and lets browsers make insecure first connections.

Why AI tools generate it

Local dev often runs on http, and AI-generated deploys can surface the insecure origin or fail to send HSTS, leaving the hardening gap in place.

How DevMeth detects it

A read-only live probe checks whether an http request to your site redirects to https (301) and whether https responses carry a long-lived HSTS header.
