A lot has happened in the world of encryption since the 2017 TLS Telemetry Report. Over the past two years, standards have been updated, browsers have evolved and a number of new protocols have been released that aim to secure all the remaining cleartext protocols still in wide use today.
These new protocols don’t come without their share of concern, however. In early 2019, security researchers found the first malware sample making use of the emerging Domain Name System (DNS) encryption protocol, DNS-over-HTTPS (DoH). Clearly, threat actors waste no time in using the latest encryption advances to their advantage.
This report provides deep insight into how encryption on the web is constantly evolving. It looks into which ciphers and SSL/TLS versions are being used to secure the internet’s top websites, examines the use of digital certificates on the web, and looks at supporting protocols (such as DNS) and application layer headers.
