Encrypted traffic is on the rise. In 2016, NSS Labs found out that 97% of surveyed enterprises saw an increase in encrypted web traffic. Both Let's Encrypt and Google currently report between 70% and 90% of traffic is HTTPS (HTTP encrypted with SSL/TLS). Google has been pressing for HTTPS for a while now. Back in 2014, they started taking into account whether the website uses HTTPS for page ranking, and in 2017 Google Chrome browser started showing "Not Secure" warning in the address bar when visiting websites without HTTPS. In August 2018, Scott Helme, a Security Researcher, analyzed 1 million most popular websites - over 51% are already using HTTPS. Gartner predicts 80% of traffic will be encrypted in 2019.
