What is changing?
Microsoft, Google, Apple, Mozilla and other major technology vendors are deprecating support of TLS versions 1.0 and 1.1 in 2020. Popular web browsers will continue to function but start showing alerts when TLS 1.0 or 1.1 web communication is encountered, and server-to-server communications will also change.
Transport Layer Security (TLS) is a security protocol to encrypt and authenticate secure connections across the web, either from a web browser or between web servers. TLS version 1.0 was first defined in 1999, and version 1.1 was introduced in 2006. Due to evolving regulatory requirements and new security vulnerabilities, technology providers have been deprecating their support of TLS versions 1.0 and 1.1.
How will this impact me?
ClickDimensions and Microsoft have been taking steps to ensure that cloud services will not be impacted.
You will not be impacted if . . .
Your organization’s websites and web applications are hosted by ClickDimensions, Microsoft, or other major cloud or SaaS providers.
You will be impacted if . . .
- Your organization uses CRM on premise running on Windows Server version 2012 R2 or older. These older operating systems used TLS 1.1 by default. In order to avoid TLS alerts or errors, update your CRM server environment. Learn more from Microsoft.
- Your organization or an IT provider hosts websites, microsites, or web applications on local web servers that are still using TLS 1.0 or 1.1. In order to avoid TLS alerts or errors, update your web server(s). Learn more from Microsoft.
