Enhancing Cybersecurity and Data Integrity for a Healthcare Service Provider

Visualization of encrypted data transmission and storage processes across healthcare databases and cloud environments.

Focus Areas

Cybersecurity

Data Integrity & Governance

Regulatory Compliance (HIPAA)

Automated process for data integrity validation and audit logging within a healthcare system.

Business Problem

A national healthcare service provider responsible for managing sensitive patient health records and operational data was exposed to rising cyber threats. Fragmented security controls, legacy systems, and limited visibility across digital assets created vulnerabilities. The organization needed to modernize its cybersecurity infrastructure, ensure real-time data integrity, and achieve sustained compliance with healthcare regulations.

Key challenges:

  • Legacy Systems and Outdated Protocols: Inconsistent patching and lack of centralized monitoring increased the attack surface.

  • Data Silos and Inconsistent Standards: Health data resided across unintegrated systems with limited validation.

  • Limited Threat Detection Capabilities: The absence of real-time monitoring and automated response delayed incident mitigation.

  • Manual Compliance Reporting: Auditing processes required significant manual documentation and were error-prone.

The Approach

Curate partnered with the healthcare provider to implement a zero-trust security framework and enforce robust data governance policies. By leveraging modern cloud security tools, machine learning-driven threat detection, and real-time data validation workflows, the organization strengthened its security posture and regulatory alignment.

Key components of the solution:

  • Discovery and Requirements Gathering:

    • Security Risk Assessment: Evaluated current threat landscape, network architecture, and access points.

    • Stakeholder Interviews: Engaged IT, compliance, and clinical operations teams to define data sensitivity tiers and security requirements.

    • Policy Review: Analyzed existing security protocols and compliance frameworks to identify gaps.

    • Data Inventory and Mapping: Cataloged data flows, storage locations, and ownership.

  • Solution Design and Implementation:

    • SIEM Deployment: Implemented Splunk to centralize log data, correlate events, and generate real-time alerts.

    • Access Control Overhaul: Adopted Azure AD and Okta to implement MFA and least-privilege access across systems.

    • Data Validation Pipelines:

      • ETL workflows were enhanced with schema checks, encryption, and integrity verification.

      • Patient records were monitored for anomalies and tampering.

    • Compliance Automation: Integrated tools like Drata for continuous control monitoring, policy tracking, and audit readiness.

    • Automated Incident Response: Leveraged SOAR tools to triage alerts, assign severity, and trigger containment actions.

  • Process Optimization and Change Management:

    • Security Governance Council: Established cross-functional oversight for policies and risk reviews.

    • Training & Awareness: Conducted quarterly phishing simulations and compliance workshops for staff.

    • Documentation and Reporting Templates: Streamlined compliance artifacts to reduce audit preparation time.

    • Feedback Loops: Regular vulnerability assessments and internal audits guided ongoing enhancements.

Business Outcomes

Increased Data Protection and Visibility


Modern SIEM and IAM solutions provided unified oversight of systems and access behavior, reducing attack vectors.

Stronger Regulatory Compliance


Automation and consistent monitoring ensured alignment with HIPAA and HITRUST standards with reduced manual overhead.

Improved Data Quality and Integrity


Real-time data validation workflows ensured consistency, accuracy, and trust in patient and operational data.

Audit Faster Response to Threats


Automated alert triage and containment workflows significantly shortened the incident response lifecycle.

Sample KPIs

Here’s a quick summary of the kinds of KPI’s and goals teams were working towards**:

Metric Before After Improvement
Mean Time to Detect (MTTD) 36 hours 3 hours 91% faster detection
Mean Time to Respond (MTTR) 4 days 5 hours 95% improvement
Compliance audit preparation effort 8 weeks 1.5 weeks 81% reduction
Data integrity errors per month 42 6 86% reduction
User access policy violations 30/month 4/month 87% reduction
