Over the past several years, internet standards and regulatory bodies have deprecated or disallowed TLS versions 1.0 and 1.1, due to a variety of security issues. We have been tracking TLS protocol usage for several years and believe TLS 1.0 and TLS 1.1 usage data are low enough to act. To increase the security posture of Windows customers and encourage modern protocol adoption, TLS versions 1.0 and 1.1 will soon be disabled by default in the operating system, starting with Windows 11 Insider Preview builds in September 2023 and future Windows OS releases. There is an option to re-enable TLS 1.0 or TLS 1.1 for users who need to maintain compatibility.
What about all those SMBs using TLS 1.0/1.1?
