1. Introduction

This document summarizes the security controls, compliance posture, and risk management practices for Hiive Health’s Prior Authorization (ePA) System. It is intended for clients, partners, and prospective customers evaluating our security and compliance readiness.

The ePA System processes electronic Protected Health Information (ePHI) — including patient demographics, clinical documentation, diagnostic information, and insurance records. Security and regulatory compliance are foundational to the platform’s design and operation.

Each control area described below is backed by detailed internal documentation, including full policy documents, technical implementation guides, risk registers, and operational runbooks. These materials are available upon request as described in Section 11.

2. Compliance Framework

Current Compliance Status

2.1 HITRUST CSF Alignment

HITRUST Common Security Framework (CSF) certification is a recognized gold standard for healthcare technology vendors. While HiiveHealth is not yet HITRUST certified, our current security posture represents substantial alignment with HITRUST requirements — and we are not starting from scratch.

What we already have that maps directly to HITRUST CSF:

• Security Hub CSPM running CIS AWS Foundations Benchmark v5 and NIST 800-53 — two of the primary reference frameworks that HITRUST CSF draws from. Months of continuous compliance scoring data against these standards is the kind of evidence a HITRUST assessor expects to see.

• IAM password policy enforced via AWS Control Tower guardrails — org-wide enforcement across all accounts, which is the authoritative mechanism and satisfies the HITRUST control requirement

• 15-policy HIPAA framework (HIIVE-SEC registry) — maps directly to HITRUST control categories 01–09 (access control, audit, incident management, risk management, training, and more)

• Formal NIST SP 800-30 risk assessment — satisfies HITRUST’s requirement for a documented, methodology-driven risk analysis

• GuardDuty, Inspector, Macie, and Control Tower — satisfy several HITRUST-specific control requirements around continuous monitoring, vulnerability management, and data classification that many organizations do not have in place at all

• 100% HIPAA Security Rule compliance — HIPAA compliance is a prerequisite for HITRUST, and we have achieved it fully

• Complete audit trail — 6-year retention, full PHI query logging, tamper-proof log storage; HITRUST assessors require evidence of exactly this

What remains HITRUST-specific before formal certification:

• Customer-managed KMS keys for CloudWatch Logs and Secrets Manager (currently AWS-managed keys, which satisfy HIPAA; CMK is a HITRUST hardening requirement)

• Formal HITRUST assessment engagement and remediation cycle

• A small number of CIS benchmark hardening items that Security Hub is already continuously surfacing and tracking

Timeline: Formal HITRUST CSF assessment and certification is planned as a strategic initiative following the completion of cross-region DR. Our current posture means the assessment process will be a refinement exercise rather than a foundational build.

Assessment Methodology

Risk assessments follow NIST SP 800-30 Rev. 1, adapted for healthcare regulatory requirements and consistent with OCR guidance on HIPAA Security Rule risk analysis. Our assessment program includes:

• Comprehensive analysis of all systems containing ePHI

• Threat and vulnerability identification using CVSS v3.1 scoring

• Likelihood × Impact risk matrix aligned with NIST standards

• Documented risk treatment decisions with compensating controls

• Continuous automated compliance scoring via AWS Security Hub CSPM across all accounts

• Semi-annual interim reviews and annual comprehensive assessments

Latest Assessment Results (April 20, 2026):

• 0 CRITICAL unmitigated risks

• 0 HIGH unmitigated compliance risks (cross-region DR is an infrastructure enhancement with documented interim controls)

• 32 of 32 identified gaps remediated — 100% gap closure

• Overall HIPAA compliance: 100%

• Overall risk rating: LOW

Detailed assessment findings, risk registers, and remediation tracking are maintained in separate internal documents available under NDA.

SOC 2 Readiness

Our internal compliance program is built on controls that directly align with AICPA Trust Service Criteria (TSC). The HIPAA risk assessment — conducted using NIST standards — provides substantial overlap with SOC 2 requirements. Our centralized Security Hub CSPM running CIS v5 and NIST 800-53 generates continuous compliance evidence directly applicable to SOC 2. Formal SOC 2 Type II certification is on our roadmap.

3. Security Controls

3.1 Access Control & Authentication

3.2 Encryption

3.3 Data Integrity & Processing

3.4 Container & Compute Security

3.5 Data Classification & Confidentiality

4. Continuous Security Monitoring

HiiveHealth operates a centralized security monitoring platform across all AWS accounts in the organization, providing real-time threat detection, vulnerability management, and compliance scoring.

This continuous monitoring architecture means security and compliance posture is assessed in real time — not just at point-in-time audits.

5. Audit & Logging

HiiveHealth maintains a multi-layered audit architecture that meets or exceeds HIPAA retention requirements:

All retention periods meet or exceed the HIPAA 6-year retention requirement (§164.316(b)(2)(i)).

6. Incident Response & Business Continuity

Incident Response

HiiveHealth maintains a formal Incident Response Plan covering:

• 7-phase response process: Detection → Triage → Containment → Eradication → Recovery → Notification → Post-Incident Review

• Severity classification: Critical, High, Medium, Low — with defined response times for each level

• Automated detection: GuardDuty and Security Hub provide real-time alerting that feeds directly into the incident response workflow

• Breach notification: Compliant with HIPAA Breach Notification Rule (45 CFR §164.400-414) — 60-day notification timeline with documented templates and HHS reporting procedures

• Post-incident review: Root cause analysis, lessons learned, and control improvements documented after every incident

Business Continuity & Disaster Recovery

7. Administrative Safeguards & Governance

Policy Framework

HiiveHealth maintains 15 formal HIPAA security policies (HIIVE-SEC-001 through HIIVE-SEC-015) covering all required administrative, physical, and technical safeguards:

Risk Assessment Program

Business Associate Agreements

BAAs are in place with all vendors that process or may incidentally access ePHI:

• AWS — Infrastructure hosting (all HIPAA-eligible services)

• Slack — Team communications (evaluated and resolved)

• PagerDuty — On-call alerting (evaluated and resolved)

8. Infrastructure Architecture

The ePA System is deployed on AWS using a security-first, defense-in-depth architecture:

Hiive ePA AWS infrastructure architecture: public subnet with load balancer, private subnet with ECS Fargate services, database subnet with Aurora PostgreSQL, and org-wide guardrails

Key Architecture Decisions:

• No PHI on the public internet — All PHI systems reside in private subnets

• IAM-exclusive database authentication — Static database credentials eliminated from the application authentication path

• AWS-managed services — Leverages AWS’s SOC 2 Type II, HIPAA-eligible infrastructure

• Ephemeral compute — Stateless containers with read-only filesystems and no persistent local storage

• Continuous monitoring — Security Hub, GuardDuty, Inspector, and Macie running org-wide

• Defense in depth — Control Tower SCPs and guardrails, VPC isolation, security groups, NACLs, encryption, IAM, and application-level controls

9. SOC 2 Trust Service Criteria — Coverage Summary

Overall SOC 2 Readiness: HIGH — The majority of controls required for SOC 2 Type II certification are implemented and documented. The continuous Security Hub CSPM scoring against CIS v5 and NIST 800-53 generates ongoing compliance evidence directly applicable to SOC 2 Type II examination.

10. Identified Gaps & Remediation Roadmap

Recent Improvements (February–April 2026):

• check 100% HIPAA Security Rule compliance achieved — all 32 identified gaps resolved

• check Centralized security monitoring deployed org-wide — Security Hub CSPM, GuardDuty, Inspector, Macie, Control Tower across all accounts
