Keeping Your Sites and Users Safe Using SSL

Keeping your users’ data safe is important in the digital age. People’s entire lives are now online in some way. One of the first things you can do to ensure your users’ safety is to ensure their data is transmitted to you and back securely, and for that, we use SSL. SSL is the tool responsible for HTTPS and the little safe green lock in your browser telling your user that any data they transmit to your site will be done securely.
