Nephroflow

NephroFlow is a process-driven dialysis software platform designed to streamline care planning and workflow management for medical professionals. Used by healthcare providers and patients, the platform handles sensitive medical information and integrates with medical device infrastructure via server communication.

Operating in a healthcare environment introduces strict security requirements, including:

• Protection of patient data
• Strong authentication and authorization controls
• Secure role-based access management
• Resistance to denial-of-service attempts
• Protection of proprietary algorithms and intellectual property
• Compliance with ISO 27001 (ISO27k) information security standards

Given the critical nature of healthcare data and regulatory expectations, NIPRO Digital required structured, recurring penetration testing to validate system resilience annually.

Cyrex conducted structured white and grey box penetration testing across both the web and mobile versions of NephroFlow.

With architectural visibility and realistic attack simulation, we evaluated both internal logic and externally exposed components.

Our engagement included evaluation of:

• Patient data privacy controls
• Role-based access controls and permission boundaries
• Authentication and authorization workflows
• Denial-of-service resilience
• Business logic integrity
• Intellectual property protection mechanisms

Special attention was given to ensuring secure communication between the application and backend services, particularly as the system interacts with medical devices via server-only integration.

The penetration testing engagement supports NIPRO Digital’s ISO 27001 certification efforts by providing:

• Documented security assessments
• Prioritized vulnerability reporting
• Clear remediation guidance
• Regression testing after patching

During testing, Cyrex identified multiple high-priority vulnerabilities, which were addressed promptly by the development team.
