Multi-cloud security for PHI is not optional. Storing Protected Health Information across AWS, Azure, and GCP creates new attack surfaces. Each environment has its own IAM model, encryption options, network controls, and policy enforcement quirks. A gap in one platform becomes a gap in all of them when systems are interconnected.
HIPAA and HITECH demand strict safeguards for PHI. In a multi-cloud setup, compliance requires unified policy definitions, consistent encryption at rest and in transit, and continuous monitoring of every data boundary. Relying on native tools from each cloud without integration leaves blind spots. Attackers exploit the weakest link.
Zero trust architectures help, but only if they are implemented across every platform and account. Automate least-privilege access, verify every identity, and remove unused credentials quickly. Map data flows to know exactly where PHI exists, and apply tokenization or field-level encryption to minimize exposure.
