Take a look at your browser’s address bar, you should see a lock icon next to the website address, right? It means that now we are more secure and all traffic made on our site is encrypted over a secure channel. In simpler terms, visiting an HTTPS site, rather than a regular old HTTP site, protects you against an array of malicious activities, including site forgery and content alteration.
We do care for security, as anyone on the internet (should). Securing website is no longer a matter choise, it’s a necessity. As stated by Google in a post on it’s Security’s Blog:
HTTPS is fundamental to internet security; it protects the integrity and confidentiality of data sent between websites and visitors’ browsers.
What does it mean for a visitor? Do you have to change your browser or device? Absolutely not! You will continue to browse our site the same way as before, using the same browser and platform. You will benefit of encrypted contents automatically, without any user intervention.
