Wikipedia says:
HTTPS is especially important over insecure networks (such as public Wi-Fi access points), as anyone on the same local network can packet-sniff and discover sensitive information not protected by HTTPS.
That’s enough, for us security in the WEB is crucial, so we decided to use only HTTPS connections. Not only that, all the services we offer, including CDN and API, are exclusively encrypted with SSL protocols and, where possible, we use client-side tools to avoid data transfer to the network.
But out of dotmaui.com the web is still full of sites with unsafe connections, so we recommend using the HTTPS Everywhere extension.
HTTPS Everywhere is a Firefox, Chrome, and Opera extension that encrypts your communications with many major websites, making your browsing more secure.
For those who have a website and have the ability to configure a certificate, we have implemented, on dotmaui.com, HTTPS free for everyone, A program created by Daniel Roesler and available on GitHub, which allows you to create free certificates.
