The Hypertext Transfer Protocol (HTTP) has had a good, long run for over 25 years. However, it is about to be called out as not-secure starting today since it lacks sufficient protections to safeguard communications against eavesdropping and tampering.

Google has been ramping up its efforts against the use of HTTP in favor of its secure successor, the HTTPS. Along with other industry leaders, including Mozilla, Apple, and Microsoft, the browser make has been pushing websites to switch to HTTPS. With the release of Chrome 68 today, Google has now started labelling websites not using HTTPS as “not-secure.”
