Zero infrastructure. Maximum control.

Correct — Sirona requires no on-premise PACS servers or storage arrays. The only requirement is business-class internet from your sites to AWS; site integrations run over an encrypted tunnel or a small edge router that Sirona configures with you. Studies and reports are delivered over a global CDN, and multiple sites all connect to the same cloud platform — no replication appliances.

Disaster recovery is built into Sirona's architecture. Data is replicated across multiple availability zones automatically, with built-in failover that keeps studies and reports accessible. You don't need to procure a secondary PACS, configure replication appliances, or manually test failover — Sirona maintains a disaster-recovery plan and exercises it. Broader cross-region disaster recovery is on our roadmap for H1 2027.

Sirona applies security patches and feature updates continuously, without downtime. Updates roll out to the platform, not to individual customer installations, so there are no maintenance windows to schedule. New capabilities are introduced behind managed feature flags.

Sirona integrates with your EMR or RIS over standard HL7 interfaces. Your EMR or RIS sends demographics and orders as HL7 ADT and ORM messages. Sirona builds worklists from them, and when a report is signed it returns the result as an HL7 ORU message. Sirona's integration team handles the interface engineering for every site.

Sirona is built for HIPAA. Changes to clinical information — patient and order updates and study lifecycle events — are logged to durable, access-controlled storage that supports HIPAA audit requirements, with no separate logging appliances for your team to manage. Sirona runs an active SOC 2 Type II program — attestation available under NDA.

Sirona ingests your existing PACS archive directly via DICOM protocol. How long the historical archive takes depends on its size and your bandwidth, and the transfer runs in the background while reading continues. Once the historical archive is loaded, Sirona becomes your system of record for new studies while you keep your legacy PACS running read-only for edge cases. You can migrate gradually — no forced cutover weekend.
