Atlassian Guard is Atlassian’s organization-level cloud security add-on for Atlassian Cloud. It centralizes identity and access management (IAM) controls (e.g., SAML SSO, SCIM provisioning, enforced MFA/2SV, authentication policies) and, in the Premium tier, adds security monitoring and data protection capabilities (e.g., detections, investigation workflows, data classification and DLP-like controls) across supported Atlassian cloud apps.
Guard is offered as an organization-level subscription layered on top of existing Jira/Confluence/Bitbucket/Trello/JSM Cloud subscriptions, providing governance and security controls at the organization admin console level rather than per-site or per-product. Atlassian frames Guard around the concepts "protect, detect, respond" for cloud use.
Key official pages describing the product and capabilities include product overview and feature pages, Guard Premium documentation, and Guard licensing/FAQ pages.
