Is Your Website's HTTPS Actually Secure?
A green padlock isn't the whole story. Check whether your site has HSTS, automatic HTTP→HTTPS redirect, no mixed content, and modern TLS — the things that separate "has SSL" from "actually protects users."

What "Secure HTTPS" Actually Means
Most website owners check SSL by looking for the green padlock and stop there. Attackers don't stop there. The padlock just means "this connection is encrypted right now" — it says nothing about whether the next connection will be downgraded to HTTP, whether your cookies leak over plain HTTP, or whether mixed-content scripts can be tampered with.
Real SSL security has 4 layers: (1) HTTPS coverage — every page, including www and non-www. (2) HSTS — tells browsers to refuse HTTP forever, ideally with preload. (3) HTTP→HTTPS redirect — so someone typing your domain doesn't briefly hit the unencrypted version. (4) No mixed content — every script, image, and font on HTTPS pages must also be HTTPS.
Skip any one of those and your "SSL" can be downgraded by an attacker on the same WiFi network. The scan checks all four in 30 seconds and tells you exactly which are missing.
FAQ
Common questions from Omaha business owners
No. The padlock means the current connection is encrypted, but it doesn't mean HTTP is blocked, that HSTS is set, or that mixed content isn't leaking data. A site can have a perfectly valid certificate and still be downgraded to HTTP by an attacker on public WiFi.
