Google and SSL: HTTP sites are flagged as insecure
Chrome 56
The latest version of Google Chrome (Chrome 56) is rolling out worldwide this month. The update of the browser will display a warning that websites that do not use encryption are unsafe. Google points out that "users are blinded by security notifications and therefore will show when a website is not. In the not too distant future, Google is expected to expand the warning with a red triangle, where at the time of launch it would be a more neutral symbol.
If you, as a merchant, do not want to have a warning that your website is insecure, it is advisable to purchase an SSL certificate.
