SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is an industry standard and is used by millions of websites in the protection of their online transactions with their customers.
When you have an SSL certificate your browser address will go from ‘http://’ to ‘https://’, this extra s means the connection is secure and customers can be reassured that any personal information they enter on your website won’t be encrypted and unreadable by hackers intersecting messages.
This becomes particularly important for websites with eCommerce setup to prevent any credit card data from being stolen while purchasing products.
