Atlassian Cloud vs Data Center Security and Compliance

Updated 4 November 2026 · Standard formula, shown below

Atlassian Cloud and Data Center differ significantly in security control and compliance: Cloud offers automated, shared-responsibility security with continuous compliance updates, while Data Center gives you direct control over infrastructure, data residency, and compliance through self-managed security measures. Your choice depends on regulatory requirements, team size, and operational capacity.

Background: Two Deployment Models

Atlassian provides two primary deployment options for Jira, Confluence, and other products. Cloud is a software-as-a-service (SaaS) offering hosted on Atlassian’s infrastructure, with Atlassian managing servers, security patches, and compliance certifications. Data Center is a self-managed deployment on your own infrastructure (on-premises or in your cloud account), where you control the entire stack from the operating system up. Historically, Data Center was the choice for large enterprises needing data residency or custom security, while Cloud was simpler and cheaper. Over time, Cloud has added enterprise-grade features, narrowing the gap.

Security Control Comparison

Security controls in Cloud are managed by Atlassian under a shared responsibility model. Atlassian handles physical security, network security, OS patching, and application-level security. You manage user access, permissions, and integration security. In Data Center, you are responsible for all of these: you patch the OS, configure firewalls, manage SSL certificates, and secure the underlying servers. This gives you granular control but requires dedicated security expertise. Key differences:

Encryption: Cloud encrypts data in transit (TLS) and at rest (AES-256) by default. Data Center also supports TLS and at-rest encryption, but you must configure and manage the keys.
Identity management: Cloud supports SAML SSO, SCIM, and OAuth with Atlassian Access. Data Center supports SAML, LDAP, and Crowd, giving you more flexible integration with existing identity providers.
Audit logs: Cloud provides audit logs for admin actions and some user activities. Data Center offers more detailed audit logging, including access to raw logs and integration with SIEM tools.
Network controls: Cloud allows IP allowlisting and VPN, but Data Center lets you place the application entirely within a private network, with no exposure to the public internet.

Compliance Certifications and Standards

Atlassian Cloud maintains a broad set of compliance certifications, including SOC 2, SOC 3, ISO 27001, ISO 27018, PCI DSS, and HIPAA (for eligible products). These are continuously audited and updated. Data Center does not come with these certifications directly; instead, you inherit compliance from your own infrastructure and must implement controls to meet standards like SOC 2 or HIPAA. However, Data Center allows you to deploy in regions that meet specific data residency laws, such as GDPR or the Australian Privacy Act, by keeping data within your chosen jurisdiction. For highly regulated industries like finance or healthcare, Data Center’s control over data location and audit trails can be essential.

Data Residency and Sovereignty

Cloud offers data residency in specific regions (US, EU, Australia, etc.) but you cannot choose the exact data center location within that region. Data Center lets you host data anywhere, including on-premises, giving you full control over data sovereignty. This is critical for organizations with strict data residency requirements, such as government agencies or companies in countries with data localization laws. For example, a bank in Germany may need to ensure data never leaves the EU; Cloud’s EU region may suffice, but a Data Center deployment in a Frankfurt data center gives more explicit control.

Common Security Challenges and Misconceptions

A common misconception is that Cloud is less secure because it is multi-tenant. In reality, Atlassian isolates customer data and invests heavily in security, often exceeding what a typical IT team can achieve. However, Cloud’s shared responsibility means you must configure security correctlyâ€”misconfigured permissions or weak SSO policies can expose data. Data Center’s main challenge is keeping up with security patches; many breaches occur because organizations fail to apply Atlassian’s critical security updates. Another issue is that Data Center’s flexibility can lead to insecure configurations, such as leaving admin consoles exposed to the internet. Both models require active security management, but the focus differs: Cloud on configuration, Data Center on infrastructure.

Cost and Operational Impact

Cloud uses a per-user subscription model, which includes security maintenance and compliance updates. Data Center has a tiered licensing cost based on the number of users, but you must also pay for infrastructure, IT staff time, and security tools. For small teams under 50 users, Cloud is almost always more cost-effective. For large enterprises, Data Center can be cheaper in raw licensing but requires significant operational investment. Security-wise, Cloud’s automated patching reduces the risk of unpatched vulnerabilities, while Data Center’s manual patching can be a liability if not diligently managed. You should factor in the cost of a security engineer’s time when comparing total cost of ownership.

How to Choose

Evaluate your organization’s security and compliance needs against your operational capabilities. Consider these factors:

Regulatory requirements: If you need specific certifications like HIPAA or PCI, Cloud may be easier because Atlassian already holds them. If you need to meet a custom framework or data residency, Data Center offers more control.
Team size and growth: Cloud scales automatically and is ideal for agile teams. Data Center is suited for large, stable user bases (typically 500+ users).
IT resources: If you have a dedicated security team, Data Center is viable. If not, Cloud’s managed security reduces the burden.
Integration needs: Data Center allows deeper integration with on-premises tools and custom security controls. Cloud has a rich ecosystem but limited network-level control.

Frequently Asked Questions

Is Atlassian Cloud HIPAA compliant? Yes, Atlassian Cloud offers HIPAA compliance for Jira and Confluence on eligible plans, provided you sign a Business Associate Agreement (BAA) and enable required security features. Data Center does not have a BAA; you must implement HIPAA controls yourself.

Can I use my own encryption keys in Cloud? No, Atlassian Cloud manages encryption keys for data at rest. You can use your own keys for certain features like encryption of attachments, but not for the core database. In Data Center, you control all encryption keys.

Does Data Center support single sign-on (SSO)? Yes, Data Center supports SAML SSO and LDAP integration. Cloud supports SAML SSO with Atlassian Access, which is an add-on for Cloud plans.

Which is better for GDPR compliance? Both can be GDPR compliant. Cloud provides data processing agreements and data residency in the EU. Data Center allows you to keep data entirely within your own EU infrastructure, which may simplify compliance if you have strict data minimization requirements.

What happens to my data if I move from Data Center to Cloud? Atlassian provides migration tools, but you should plan for a security review of your new Cloud configuration. Data is encrypted during migration, but you must ensure your Cloud setup meets your compliance needs before moving.

Are there any security features exclusive to Data Center? Yes, Data Center offers more granular audit logging, the ability to use custom security plugins, and full control over network segmentation. Cloud has some advanced features like IP allowlisting, but Data Center’s flexibility is unmatched.
