HTTP vs HTTPS — what's the difference?
HTTP is the protocol browsers use to talk to websites. HTTPS is the same protocol with encryption added (the “S” is for Secure). The difference is who can read the traffic in between.
The real difference
- HTTP — data travels in plain text. Anyone between the visitor and the server (on public Wi-Fi, an ISP, a compromised network) can read or tamper with it.
- HTTPS — data is encrypted with a TLS certificate. Eavesdroppers see only scrambled bytes; the content and the visitor’s actions stay private, and the data can’t be silently modified in transit.
That padlock in the address bar means the connection is encrypted and the site presented a valid certificate for its domain.
Why every site needs HTTPS now
- Security — passwords, form data, and payments must never travel in plain text.
- Trust — browsers mark plain HTTP sites “Not secure,” scaring visitors off.
- SEO — search engines favor HTTPS.
- Modern features — many browser APIs (service workers, etc.) only work over HTTPS.
There’s no real reason to run plain HTTP anymore.
What makes HTTPS work: certificates
HTTPS needs a TLS/SSL certificate that proves the site owns its domain. A trusted authority issues it; the browser checks it on every connection. Learn more: what is SSL.
Getting HTTPS (free)
OrbixPanel issues free, trusted certificates from Let’s Encrypt and renews them
automatically, then redirects http:// to https:// for you — see
how free SSL works. You don’t pay for or
manually renew anything.
Common HTTPS pitfalls
- Mixed content — an HTTPS page loading some assets over HTTP shows a warning → fix SSL errors.
- Redirect loops when HTTPS is misconfigured behind a proxy → too many redirects.
