Patient data is sacred. We conducted a rigorous security audit and pentest for a medical software provider, ensuring their encryption and access controls met the strictest EU and US regulations.
1. The Client
A B2B SaaS provider offering telemedicine solutions and patient management systems for hospitals. The company holds sensitive medical records (PHI/PII) and operates in strictly regulated markets (EU and USA).
2. The Challenge
The client was preparing for a major investment round and needed to prove their security posture to investors. They required a comprehensive White Box Penetration Test (with full access to source code) to ensure deep compliance with GDPR (Europe) and HIPAA (USA) standards.
3. The Solution: White Box & Architecture Review
We approached this project with a “defense-in-depth” strategy.
-
Source Code Review: Our pentesters analyzed the codebase for insecure cryptographic implementations.
-
Architecture Audit: We verified how data was stored, processed, and transmitted.
-
Role-Based Access Control (RBAC) Testing: Checking if a doctor could see data they shouldn’t, or if a receptionist could access medical history.
4. Critical Findings
-
High: Broken Object Level Authorization (BOLA) A doctor from “Hospital A” could access patient records from “Hospital B” by simply guessing the sequential Patient ID in the URL. This is a top-tier vulnerability in SaaS architectures.
-
High: Weak Encryption at Rest Database backups were stored using outdated encryption standards, which could be cracked by modern hardware if stolen.
-
Medium: Session Management Issues Sessions did not expire properly after logout, allowing potential access if a device was stolen.
5. The Result
-
Regulatory Compliance: The client implemented strong encryption and fixed the RBAC issues (BOLA). Our final report served as proof of compliance for the investors.
-
Investment Secured: The demonstrated commitment to security and the clean re-test report helped the client successfully close their Series B funding round.
-
Trust: Hospitals using the platform received assurance that their patient data is safe behind Pentestica’s verified defenses.
