Beginning in July 2018 with the release of Chrome 68, Chrome will mark all HTTP sites as “not secure”.
It means that Google Chrome will show “Not secure” on the address bar when a user visits a website that does not have SSL certificate. It will probably affect the company branding and may makes customer feels that visiting the website is not safe. In the future, other web browsers will probably implement same practice. It’s better to buy SSL certificate for your website if you concern about your branding. Please contact us if you need help.
