- Encyro, Inc.How to Check the TLS Version on a Website: 4 Easy MethodsThe TLS 1.0 protocol dates back to 1999 and offers very poor levels of security against the attacks that are prevalent in today's environment. Most modern web browsers and cloud service providers dropped support for the TLS 1.0 and TLS 1.1 protocols earlier this year and the IETF TLS WG has submitted a "die-die-die" internet draft for TLS 1.0 and TLS 1.1 to the IESG for publication as an RFC.
