Core Integration Capabilities

Interoperability

ViHA has a vendor-agnostic standards-based integration layer — speaking HL7 FHIR R4/R5, REST, SMART on FHIR, HL7 v2.x, and SFTP natively. It integrates with EMRs, HIS, laboratory platforms, claims systems, and HIEs.

Access Governance and Tenant Isolation

ViHA enforces role-based access control at every API boundary — governing which systems and user roles can read or write each data domain. Tenant isolation ensures complete separation between organizations sharing infrastructure. Identity federation via SAML 2.0 and OIDC integrates with your existing identity provider, and every access event is captured in an immutable, tamper-proof audit log.

Infrastructure Scalability

ViHA is built for deployment at any scale — from single-site pilots to national outcomes programs serving millions of patients. Its cloud-native architecture scales horizontally with patient volume and user load, with multi-tenant isolation enforced at every API boundary. Our deployment models ensure alignment with local data residency and digital health governance requirements wherever you operate.
