TLS and Secure Cipher Suites in 2026
TLS It's been 4.5 years since I last wrote about the state of TLS and secure cipher suites . A lot has changed in that time including some updates around TLS and cipher suites, so I wanted to provide an update while it has been on my mind. First and foremost -- TLS 1.3 is gaining ground. Qualys' SSL Labs shows that even as of June 2025, 75% of sites surveyed supported TLS 1.3 . This is great news, and I look forward to continued adoption of TLS 1.3 and it eventually becoming the norm. I will link again to two fantastic Cloudflare blog posts that explain the details and benefits of TLS 1.3, but I am looking forward to the following changes in particular: It's faster . I don't just care about security, I also care about performance and stability. TLS 1.3 reduces the number of required round-trip communications from two to one thereby reducing the total amount of time needed for a connection.
