Degroof Petercam Systems Audit
Cyrex partnered with Bank Degroof Petercam to design and deploy a secure API sandbox environment, supporting the bank’s open banking strategy and enabling partners to safely test integrations without impacting production systems.
The Challenge
Enabling Secure Open Banking with API Sandboxing
Bank Degroof Petercam, the largest independent private bank in Belgium, operates across multiple European markets and provides private banking, asset management, and corporate finance services.
With the industry shift toward open banking, the bank identified the need to:
- Provide API access to customers and partners
- Enable secure sandbox testing environments
- Protect production systems from external development activity
- Support its broader digitalisation strategy
While the internal teams had strong product expertise, they lacked the bandwidth and specialized experience to build a professional-grade sandbox environment aligned with security and API best practices.
The objective was to create a secure, scalable API sandbox that could serve as the foundation for future open banking initiatives.
The Cyrex Solution
Design & Deployment of a Secure API Sandbox Environment
Cyrex worked closely with Bank Degroof Petercam’s technical teams to design and implement a dedicated sandbox and staging environment for API consumers.
Proof of Concept & Custom Deployment
The engagement began with a rapid proof of concept, demonstrating feasibility and architectural direction.
Following validation, Cyrex delivered:
- A customized sandbox environment
- Deployment and integration of a leading API Gateway
- Secure API exposure with mock data
- Structured staging capabilities separate from production systems
The sandbox allowed developers to test integrations safely without impacting live banking operations.
API-First Foundation for Digital Strategy
The sandbox environment was built as a foundational component of the bank’s API and digitalisation roadmap.
Cyrex supported:
- API foundation integration
- Engineering services aligned with open banking standards
- Collaboration with internal technical teams
- Secure configuration and deployment practices
This ensured the solution aligned with both operational requirements and long-term strategic objectives.
The Outcome
A Secure Sandbox for Open Banking Innovation
- A production-ready API sandbox and staging platform
- Secure testing with mock data
- Integrated API Gateway deployment
- A scalable foundation for future open banking services
