Supported security protocols for Atlassian cloud apps
As industry security standards evolve for TLS and their associated ciphers, Atlassian will deprecate support for older, less secure protocols and ciphers. See the list below for the most up-to-date supported cipher suites by app.
Atlassian uses a cryptographic technology known as Transport Layer Security (TLS) to secure data sent across the internet between our customers and Atlassian cloud apps. TLS provides privacy and data integrity through the use of one or more cipher suites. A cipher suite is a combination of authentication, encryption, and message authentication code algorithms used during the negotiation of security settings and the transfer of data.

サポート対象の TLS プロトコル
TLS version 1.2 (or higher) is required for all Atlassian apps and services. TLS version 1.1 and lower is unsupported. Any version of SSL is unsupported.
サポート対象の暗号化スイート
Atlassian cloud apps may attempt to negotiate with clients using the following cipher suites. These cipher suites provide a good balance of security and performance while maintaining compatibility with almost every client or browser released in the last five years.
