Case Study

OASYS NOW

Proactive Penetration Testing for AI-Powered Health-Tech Compliance​

About the Client

OASYS NOW, founded in 2021 and headquartered in Delft, Netherlands, is a health-tech startup on a mission to make personalized healthcare accessible to everyone. The company accelerates clinical trial recruitment by leveraging AI and privacy-first technologies to match patients with relevant trials more efficiently. Its platform reflects a patient-first, privacy-by-design, and AI-native philosophy, rooted in strong European values and deep cybersecurity awareness.

The platform comprises two key products:

GRIP – a patient-facing application that allows individuals to aggregate their health records, gain personalized health insights, and discover matched clinical trials.

ELaiGIBLE – a tool for researchers and healthcare professionals that identifies eligible patient cohorts in minutes, drastically reducing recruitment timelines.

Secure Foundations Confirmed — and Clearer Compliance Path

Results:

The assessment uncovered no critical or high-severity vulnerabilities — a rare but welcome outcome. More importantly, the results validated that OASYS NOW’s engineering team had embedded privacy-by-design and security best practices into the foundation of both products.

Key observations:

Authentication and authorization logic was robust

Multi-factor authentication protected sensitive functions

File uploads, session management, and account workflows operated securely

API endpoints followed secure input validation and error-handling patterns

Cloud assets were appropriately hardened with minimal exposure or misconfiguration

All medium and low-severity issues were remediated quickly, in some cases even before final reporting was complete, thanks to Sekurno’s responsive engagement and strong developer alignment.


These results weren’t just technical milestones. The third-party attestation letter became a key asset in enterprise sales and compliance discussions, allowing OASYS NOW to provide proof of diligence and technical maturity when engaging with major healthcare partners — including large hospital systems requiring formal risk review and education around modern privacy safeguards.

The Challenge

Preparing for Enterprise Clients and Regulatory Pressure

Before engaging with Sekurno, OASYS NOW had relied solely on automated security scanning tools. But as the company matured — and began serving clinical stakeholders and institutional partners — internal diligence was no longer enough.

Their objectives were clear:

Demonstrate security maturity across both applications and infrastructure

Support compliance readiness for multiple regulatory and certification frameworks

Identify and address security blind spots that automated tools often miss

Build internal confidence and ensure responsible scaling

The company faced increasing pressure to meet stringent European and healthcare-specific security standards, including:

GDPR – for data privacy and handling of patient records

ISO 27001 – for formalized information security management

NEN 7510 – the Dutch standard for healthcare information security

EU AI Act – for ethical, transparent, and secure deployment of AI models

OASYS NOW wasn’t just responding to compliance pressure — they were proactively investing in security and privacy-by-design long before it was required. Over 18 months had been spent implementing automated monitoring and robust controls. The penetration test was initiated not to find problems, but to verify through independent validation that their safeguards worked as intended.

Our Solution

A Full-Stack Security Review Aligned to Health-Tech Demands

Sekurno delivered a comprehensive white-box security engagement that included both application and cloud-level assessments. Our scope covered the GRIP and ELaiGIBLE applications across two cloud providers: Microsoft Azure and Google Cloud Platform (GCP).

Scope of Work

Manual penetration testing with:

- DAST (Dynamic Application Security Testing)

- SAST (Static Application Security Testing)

- SCA (Software Composition Analysis)

- Manual code review targeting key logic areas

Cloud security assessments of Azure and GCP environments, focusing on misconfigurations, IAM posture, and storage/network exposure

Methodology Highlights

End-to-end validation of authentication flows (OAuth, registration, MFA, password reset)

Testing of API request handling, data access, file upload security, and privilege escalation logic

Infrastructure hardening reviews covering cloud asset exposure, role definitions, secret management, and audit logging practices

Threat modeling used to tailor the assessment to OASYS NOW’s architecture — decomposing application logic, mapping data flows, and identifying potential risks aligned with business impact

Tailored remediation recommendations delivered via interactive developer Q&A sessions

Sekurno recommended and implemented a full white-box testing approach, moving beyond gray-box limitations to ensure deep coverage. Detailed checklists and annexes mapped every finding to relevant security standards. Notably, Sekurno’s manual review uncovered that OASYS NOW’s middleware authentication logic provided full coverage of API endpoints, outperforming common industry implementations that often fail to enforce protection uniformly.

While minor challenges with Azure domain policies and multi-factor access controls made staging setup complex, both teams collaborated closely to create a secure, high-fidelity testing environment.

We felt that Sekurno really checked every bit and piece of our system. This was evident in the deliverables they provided, with full transparency — including the testing status of each OWASP WSTG requirement and testing logic informed by their own threat modeling. They were also the only team that advocated for a white-box approach — giving their security engineers deeper visibility into our application’s implementation and design, which can ultimately help with uncovering meaningful issues. It made the entire process feel aligned with how we actually build and operate.
