HIPAA Zero-Trust Architecture for 45 Connected Facilities
Executive Summary
An integrated healthcare delivery network with 45 acute hospitals, 300 outpatient clinics, and over 60,000 staff members partnered with RIVIAL DATA SECURITY to isolate critical biomedical devices, protect electronic health records, and build absolute resilience against targeted ransomware attacks.
The Security Challenge
A wave of sophisticated double-extortion ransomware campaigns was actively targeting regional health providers. The client's infrastructure contained over 180,000 connected medical IoT devices—many running legacy embedded operating systems that could not support endpoint protection agents.
The RIVIAL Solution
RIVIAL implemented an automated zero-trust microsegmentation architecture enforced at the software-defined switch port and wireless access point layer:
- • Agentless Medical IoT Profiling: Automatically fingerprinted and isolated all infusion pumps and telemetry units into dynamically restricted VLANs.
- • Ephemeral EHR Access Tokens: Clinicians authenticate through cryptographic FIDO2 tap badges, receiving short-lived scoped tokens with zero perpetual DB access.
Share your goal — let's engineer the solution.
Whether evaluating sovereign data posture, preparing for complex regulatory audits, or re-architecting enterprise infrastructure around mathematical zero-trust principles, our principal security architects provide objective, actionable guidance.
We operate with strict executive confidentiality. Initial consultation sessions are conducted under mutual NDA, providing deep technical insight without sales pressure or generic templates.
