2017 is going to be probably the most secure year for website owners because Google released updates to force people to get site SSL ready. In the coming year, Google’s browser (Chrome 56) will begin to show warning message as “Not Secure” to all HTTP sites to make the web safer and secure (less hackable) place.
SSL certificate is used to make the encrypted connection between browser and server. Therefore, Google has already moved their almost services over HTTPS encryption technology. Even WordPress has announced that they will no longer promote hosting partners until they provide SSL certificate by default in their accounts.
