# On Premises **Overview** On-prem infrastructure plays a critical role in enhancing safety for healthcare applications by ensuring that sensitive patient data remains within the provider’s secure environment. By eliminating reliance on external cloud services, on-prem deployments reduce potential exposure to third-party breaches and enable tighter access control. This localized, encrypted setup supports compliance with healthcare regulations and gives organizations full authority over data handling, retention, and audit-ability. * **Data Residency & Compliance** * On-prem deployments ensure PHI and sensitive health data never leave the provider’s infrastructure, supporting strict compliance with HIPAA, PIPEDA, and region-specific regulations (e.g., KSA, UAE, Eastern Europe). * **Isolated, Encrypted Model Hosting** * Self-hosted LLMs and inference systems run within provider-controlled environments, eliminating third-party cloud exposure and reducing attack surfaces. * Supports encrypted training and inference—including homomorphic encryption—for secure data processing even during computation. * **Operational Control & Auditability** * Providers retain full control over data access, retention, and key management, with the ability to define deletion schedules or revoke access instantly. * All infrastructure is auditable and designed to meet healthcare-grade standards for system integrity, access logging, and redundancy. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
