Security at Atlassian
Security is a top priority.
We follow extensive practices to track and protect your information through a comprehensive controls framework. Learn why thousands of customers trust us to protect their most valuable data.
Strong data encryption
Our Cloud services data is encrypted using Transport Layer Security (TLS) with Perfect Forward Secrecy (PFS). Atlassian's implementation of TLS uses strong ciphers and key-lengths by default.
Rigorous security testing
Our testing program includes threat-modeling, manual code review, automated scanning, and third-party assessments. Our bug bounty program is the cornerstone of security testing for each and every Atlassian product.
Breach detection and monitoring
We have a security monitoring team dedicated to detecting signs of a data breach. Our security practices are constantly evolving in order to address new types of security threats and further strengthen our detection capabilities.
Security news and advisories
We issue advisories when security bugs are discovered so that you can take action. Learn more about when we publish security advisories and how we determine severity levels.
