The Adobe web page or service you are trying to access, requires a more secure network connection with your web browser, operating system, or application. It is mandatory to use TLS 1.2 for secure network communication and data exchange between users systems and Adobe web services.
By the end of May 2018, Adobe deprecates support for lower versions of TLS (including TLS 1.0 and 1.1). For technical details around the TLS 1.2 protocol, see Frequently asked questions.
Modern web browsers support TLS 1.2. Usually, upgrading your browser enables you to access these services. You can download and install one of the following popular browsers:
If you're using another browser, ensure that it supports TLS 1.2.
Your operating system and application frameworks must also support TLS 1.2. If upgrading your browser does not resolve your problem, ensure that your computer meets the following system requirements:
Transport Layer Security (TLS) is a security protocol that provides privacy and data integrity between two communicating applications. It is deployed widely for web browsers and other applications that require data to be securely exchanged over a network.
According to the protocol specification, TLS includes two layers, the TLS Record protocol and the TLS Handshake protocol. The Record protocol provides connection security. The Handshake protocol enables the server and client to authenticate each other, and negotiate encryption algorithms and cryptographic keys before data exchange.
Some Adobe services are web-based. You can only engage with them through a secure network connection. TLS helps ensure that the connection between your browser and these web services is secure and reliable.
As new browsers and operating systems are released, security standards are upgraded to ensure higher levels of privacy and data integrity. However, older versions of these browsers or OS are not updated to include the latest standards.
As the acceptable level of security rises, these older, less secure browser versions and applications are left behind.
To be able to connect with secure sites, update your OS and browser versions.
There have been documented attacks against TLS 1.0 using an older encryption method and the older versions are more vulnerable than TLS 1.2. For more information, see Attacks against TLS/SSL.
Adobe has security compliance standards that require disabling support for older protocols. One such standard ensures compliance with the Payment Card Industry (PCI). PCI adaptation server is a set of security standards require organizations that accept, process, store, or transmit credit card information to maintain a secure environment.
PCI compliance mandates the use of TLS 1.1 or higher by May 2018.
It depends on the browser that you are using. All browsers mentioned in the system requirements list for Adobe services are configured to use TLS 1.2. If you are using a browser or version that does not figure in the list, update your browser.
Refer to System Requirements for list of browsers supported by Adobe services.
Adobe does not control error messages generated by the SSL communications layer. The browser generates these messages before connecting to Adobe services. Here are some examples of errors that can occur:
Internet Explorer 8 on Windows 7:
Internet Explorer 11 on Windows 7. (Internet Explorer 11 enables TLS 1.2 by default, but you can turn it off)
