Google will mark all HTTP sites that collect passwords or credit cards as non-secure
Beginning in January 2017 (Chrome 56), we’ll mark HTTP pages that collect passwords or credit cards as non-secure, as part of a long-term plan to mark all HTTP sites as non-secure.

With any of the Vigeowebsite Plans
you receive free during the first year of subscription an SSL-SD certificate and a dedicated IP, you and your customers can then securely access your website using HTTPS
