Case Study

Securing a Cloud-Based Digital Health Platform

Client Overview

  • Industry: Digital Health / SaaS
  • Product: Cloud-based platform for appointment booking, e-prescriptions, and patient record management
  • User Base: Clinics, diagnostic labs, healthcare professionals

A rapidly growing health-tech startup offering cloud-based patient services began facing serious cybersecurity concerns that threatened user trust, data integrity, and regulatory compliance.

Problem Statement

The application experienced the following cybersecurity incidents:

  • Unexpected session terminations and hijacks, impacting user continuity
  • Unauthorized visibility into sensitive patient data, indicating broken access controls
  • No formal vulnerability testing or structured incident response plan in place
  • Regulatory non-alignment with HIPAA and GDPR data protection standards

These vulnerabilities placed both the company and its users at risk of data breaches, reputational damage, and regulatory penalties.

01.

Threat Modeling & Risk Categorization

Conducted detailed mapping of all potential attack surfaces, including:

  • API endpoints
  • Login/authentication workflows
  • Encrypted and unencrypted data repositories
  • Third-party SDKs and integrations

Identified key risks such as:

  • Broken authentication
  • Insecure session handling
  • Exposure of sensitive data at rest and in transit
  • Access control misconfigurations
03.

Remediation & Preventive Security Measures

  • Patches for all critical vulnerabilities applied within 3 weeks
  • Enforced:
    – Role-Based Access Control (RBAC)
    – Session token expiration and refresh logic
    – TLS 1.2+ encryption on all endpoints
    – Data minimization and tokenization in storage
02.

Incident Response & Monitoring Setup

  • Deployed lightweight SIEM (Security Information and Event Management) to capture logs and detect anomalies
  • Developed and enforced a threat alert matrix for severity-based escalation
  • Authored internal Standard Operating Procedures (SOPs) for:
    – Handling suspected breaches
    – Escalation workflows
    – Real-time containment and forensic response
  • Trained QA, DevOps, and IT teams on Secure SDLC practices and cybersecurity hygiene

Impact

  • Zero reported security breaches after deployment of remediation measures
  • HIPAA and GDPR alignment achieved, supporting safer patient data operations
  • Marked increase in platform trust and reliability among clinical users
  • Quarterly vulnerability assessments established as a recurring part of product release cycles

Reusability

The cybersecurity framework has since been replicated and adapted for:

  • An elder-care wearable dashboard, ensuring safe biometric data monitoring
  • A teleconsultation platform for emerging markets, supporting data privacy in low-connectivity environments

The approach is scalable and portable to any health-tech or SaaS environment handling PHI (Protected Health Information) or PII (Personally Identifiable Information).

Conclusion

By embedding cybersecurity into the product’s DNA, Aiyanaar not only resolved critical vulnerabilities but also enabled the client to operate confidently in a regulated digital health ecosystem. This case highlights the importance of early threat modeling, structured response planning, and proactive compliance alignment in delivering secure, scalable SaaS medical platforms.
