'Moving to newer versions helps ensure a more secure web for everyone. While we aren't aware of significant vulnerabilities with our up-to-date implementations of TLS 1.0 and TLS 1.1, vulnerable third-party implementations do exist,' Microsoft writes. 'Two decades is a long time for a security technology to stand unmodified. Today 94 percent of sites already support TLS 1.2, while only less than one percent of daily connections in Microsoft Edge are using TLS 1.0 or 1.1. TLS 1.2, which was released ten years ago to address weaknesses in TLS 1.0 and 1.1, has enjoyed wide adoption since then, and will thus be the default TLS version unless the availability of TLS 1.3, which is currently in the development stage.Īccording to Microsoft, as TLS 1.0 continues to age, many websites have already moved to newer versions of the protocol.

Since TLS implementation in all major web browsers and applications supports downgrade negotiation process, it leaves an opportunity for attackers to exploit weaker protocols even if a server supports the latest version.Īll Major Web Browsers Will Remove TLS 1.0 and TLS 1.1 Support in 2020Īccording to the press releases published by four major companies, Google, Microsoft, Apple and Mozilla, their web browsers will completely drop TLS 1.0 and 1.1support by default in the first half of 2020.
