Starting in July, Google will start the war on insecure HTTP sites

At the same time last year Google began categorizing HTTP sites as unsafe in a move that was intended to urge site owners to switch to the HTTPS secure protocol.

After this period of time, Google has started to actually fight on sites that use HTTP. The company announced that it is warning users of these sites with the message "Not Secure", which means that the site is not safe and is in the address bar as shown in the picture.

Google will begin implementing this step in the next version of Chrome 68 browser, which will be launched in July and until that the company has confirmed to the owners of the importance of transition to HTTPS and published the way to do so.
