Dependency Audit: Third-Party Risk Review — Q3 2026

Summary
This review synthesizes findings from a dependency audit on third-party services critical to system reliability, security, and compliance. Eleven high-severity risks were identified, spanning cloud infrastructure, payment processing, identity management, legal compliance, and data encryption. All risks require immediate mitigation through dual-provider redundancy, automated failover, and on-premise fallback mechanisms. The next step is to formalize these mitigations into the product spec’s technical requirements and risk management section.

Key Risks Identified

  1. Cloud Infrastructure (AWS, Azure)

    • Risk: Regional outages could take the entire platform offline, blocking all services.
    • Severity: Critical.
    • Mitigation: Multi-cloud redundancy with automated failover and local caching for critical workflows.

  2. Identity & Access Management (IAM)

    • Risk: Failure in third-party IAM services would break user authentication, enabling unauthorized access or service lockout.
    • Severity: Critical.
    • Mitigation: Dual IAM provider redundancy with on-premise fallback for emergency access.

  3. Payment Processing (Stripe, PayPal)

    • Risk: Outages would halt revenue streams and render transactions irrecoverable.
    • Severity: High.
    • Mitigation: Dual payment processor redundancy with automated failover and offline transaction queuing.

  4. Data Encryption (Key Management Providers)

    • Risk: Failure exposes sensitive data to decryption risks, violating privacy mandates.
    • Severity: High.
    • Mitigation: Dual encryption provider redundancy with fallback to on-premise key management.

  5. Legal Compliance Tools

    • Risk: Failure could trigger legal penalties, audits, or operational shutdowns.
    • Severity: High.
    • Mitigation: Dual compliance tool redundancy with manual override capabilities for urgent regulatory changes.

  6. Machine Learning Inference Services

    • Risk: Degradation of core features (e.g., clinician documentation tools) impacts user experience and product value.
    • Severity: High.
    • Mitigation: Dual ML provider redundancy with fallback to on-premise processing.

  7. DNS & Domain Management

    • Risk: Failure renders the platform inaccessible, blocking user access and revenue.
    • Severity: High.
    • Mitigation: Dual DNS provider redundancy with automated health checks and failover.

  8. KYC Verification Services

    • Risk: Onboarding halts, violating compliance mandates and blocking revenue.
    • Severity: High.
    • Mitigation: Dual-provider redundancy with automatic failover.

  9. Analytics & Cloud Storage

    • Risk: System downtime due to API dependency failures.
    • Severity: High.
    • Mitigation: Cascading failure injectors (auth → API → DB) and IMF risk-mitigation criteria validation.

  10. ML Inference Pipelines

    • Risk: Degradation of auto-populated templates in clinician tools.
    • Severity: High.
    • Mitigation: Dual ML provider redundancy with on-premise fallback.

Mitigation Strategies

  • Redundancy: All critical services require dual-provider redundancy (e.g., IAM, payment, encryption).
  • Failover: Automated failover mechanisms must be implemented for cloud infrastructure, DNS, and payment processing.
  • On-Premise Fallback: Critical systems (IAM, encryption, ML inference) must include on-premise fallbacks to avoid single points of failure.
  • Cascading Failure Analysis: Validate dependency maps using IMF risk-mitigation criteria and inject cascading failure scenarios (auth → API → DB).
  • Stress Testing: Prioritize 10x load scenarios for high-impact dependencies (e.g., cloud storage, analytics).

Next Steps

  1. Formalize Mitigations: Embed all proposed fixes into the product spec’s technical requirements and risk management section.
  2. Validate Dependency Maps: Use IMF criteria to audit interdependencies (e.g., auth → API → DB).
  3. Implement Cascading Failure Injectors: Simulate failures in high-impact workflows.
  4. Stress Test Prioritization: Focus on 10x load scenarios for analytics, payment, and cloud storage.

Disagreements & Emphasis

  • Subrosa emphasized the criticality of cloud infrastructure and IAM over other services, advocating for on-premise fallbacks.
  • Chora prioritized formalizing mitigations as the immediate next step, aligning with the mission to bake redundancy into the product spec.
