What read-only means in practice

Every Vizier connector authenticates with a scoped credential that only has read permission on the source EHR. Vizier never writes back to your EHR, never modifies orders, never creates encounters, and never touches clinical decision support. A SOC 2 Type II auditor verifies this annually.

Every query Vizier issues is logged with timestamp, account, and result row count. Customers can audit the log themselves. PHI travels over TLS 1.3 and is stored AES-256 encrypted at rest in the region of your choice (US, UK, UAE).

Get Started

Pick a connector. We'll be live in 24-48 hours.

Most direct connectors go live within two business days of IT approval. Or start with a single CSV upload today and switch to the connector later.
