EHR integrations concentrate trust. Scheduling platforms, labs, billing tools, patient portals, and third-party applications may all exchange sensitive data through a small number of connections.
Why attackers look here first
An integration can inherit broad permissions, long-lived credentials, and access to high-value records. A weakness in authentication, authorization, input handling, or vendor configuration can create a path around controls protecting the main application.
Test the trust boundary, not only the endpoint
A useful assessment follows data from the requesting system through identity checks, business logic, logging, and downstream access. Expert-led testing validates whether a theoretical issue can expose records or disrupt clinical work without endangering care.
Turn findings into an operating decision
Prioritize issues by reachable patient data, privilege level, exploitability, and clinical impact. The result should give technical teams exact remediation steps and give leadership a defensible explanation of residual risk.
