About the Organization

A major regional healthcare network operating 25 hospitals and 150 outpatient clinics across five states, serving over 3 million patients annually. With 8,500 healthcare professionals and administrative staff, they manage one of the largest electronic health record (EHR) systems in the region.

The organization was facing mounting pressure from both regulators and patients regarding data privacy and security. Recent industry breaches and an OCR audit revealed significant gaps in their privileged access controls, putting 2 million patient records at risk and exposing them to potential HIPAA violations.

The Challenge

Protecting Patient Data While Enabling Clinical Care

Unrestricted Database Access to PHI

Over 200 IT staff, DBAs, and application developers had direct, unmonitored access to production databases containing protected health information (PHI). There was no way to track who accessed what patient data or why, creating significant HIPAA compliance risks.

OCR Audit Findings

An Office for Civil Rights (OCR) audit identified material deficiencies in access controls, audit logging, and the minimum necessary standard. The organization faced potential fines and was required to implement corrective actions within 90 days.

Excessive Vendor and Third-Party Access

Dozens of vendors supporting EHR systems, medical devices, and billing platforms had standing VPN access to production networks. Many vendor accounts were shared, making it impossible to establish individual accountability required by HIPAA.

Insider Threat Incidents

The organization experienced 6 confirmed insider threat incidents in 18 months, including inappropriate access to celebrity patient records and data exfiltration by a departing employee. Incident investigation was hampered by incomplete audit logs.

The Solution

HIPAA-Compliant Zero-Trust Access for Healthcare

The healthcare provider implemented TigerAccess to establish zero-trust controls for all privileged access to systems containing PHI, with comprehensive audit logging and session monitoring to meet HIPAA requirements.

1

Just-in-Time Database Access with PHI Logging

All database access requires explicit approval with documented justification. Every SQL query is logged with full context for HIPAA audit trails.

  • Time-bound access (1-4 hours) to Epic EHR production databases
  • Mandatory justification tied to change tickets and incident IDs
  • Complete SQL query logging with patient ID tracking
  • Real-time alerts for bulk data access or suspicious queries
2

Vendor Access Management

Eliminated shared vendor accounts and standing VPN access. All vendor access is individually authenticated, time-limited, and fully audited.

  • Individual vendor technician accounts with SSO integration
  • Session-based access tied to service tickets and work orders
  • Automatic expiration when maintenance windows close
  • Complete session recordings for Business Associate compliance
3

HIPAA-Compliant Audit Logging

Comprehensive, tamper-proof audit logs that meet all HIPAA technical safeguard requirements for access tracking and accountability.

  • Who, what, when, where for every access to ePHI systems
  • 6-year retention in WORM storage for regulatory compliance
  • Searchable audit logs for breach investigations and OCR audits
  • Automated alerts for unauthorized PHI access attempts
4

Role-Based Access with Minimum Necessary Enforcement

Implemented granular RBAC that enforces the HIPAA minimum necessary standard, ensuring users only access PHI required for their job function.

  • DBA roles scoped to specific databases and environments
  • Application support limited to non-production environments by default
  • Emergency "break-glass" access with heightened audit logging
  • Quarterly role recertification by department managers
