HTTPS and SSL – Text Version

HTTPS (Hyper Text Transfer Protocol over SSL) is the secure version of HTTP; the protocol over which data is sent between your browser and the web server.

S is for Secure

The SSL (Secure Sockets Layer) encrypts data between the browser and the server, ensuring your data, such as credit card or login details, remains private and secure.

SSL Certificate

In order for a website to use HTTPS, you need an SSL Certificate. This is a small data file that authenticates the identity of a website and acts as an electronic ‘passport’.

Once a certificate is installed on a web server, visitors can connect to your website securely via https.

Benefits of using HTTPS

The primary reason to use HTTPS is to keep sensitive user data encrypted so that only the intended recipient can read it,

You can be sure you are connected to the right website and not an impostor trying to steal your details.

Data Integrity
Data cannot be modified or corrupted during transfer without with being detached.

SEO Boost
Google prefer sites which are trusted and certified for the reasons above.

PCI Compliance
If you’re running an e-commerce site and taking payment details from customers, your site must pass certain audits to prove it is complying with the Payment Card Industry (PCI) standards. Delivering a secure website to protect user payment data via SSL is one such requirement.
