Case Study:
From Risk to Resilience: Strengthening a Financial Consortium’s Data Governance
A national consortium of banks, fintechs, and lenders had created a powerful shared database to flag suspected fraud. But with high-stakes data, legal sensitivities, and multiple member organisations involved, questions of trust, governance, and control became impossible to ignore. Could this intelligence-sharing platform hold up under regulatory or public scrutiny?
The Challenge:
Power Without Proof
The General Counsel, tasked with overseeing security and governance, saw the warning signs. While the fraud intelligence platform was operationally valuable, it lacked formalised, defensible controls. Without a mature security posture, inconsistent usage across members left the consortium exposed to reputational, legal, and regulatory risk.
The Approach:
Building Defensibility Into the Fabric
Muse was engaged through a fractional CISO model, focused on embedding robust, operationally-aligned security governance across the platform and its users.
Key initiatives included:
- Designing a Security Framework to govern how fraud intelligence was accessed and used
- Creating a Maturity Model to help member organisations benchmark and elevate their practices
- Establishing tailored Information Security Standards focused on sensitive, high-risk personal data
- Delivering Executive Dashboards for real-time visibility into posture, incidents, and readiness
- Introducing security training and onboarding for all analysts and investigators
- Authoring a Trusted Access Playbook to codify permissions, controls, and audit requirements
The Outcome:
Assured, Aligned, and Auditable
The result was a transformed operating environment — one that provided both utility and defensibility.
- All member access became secure, role-based, and fully auditable
- Decision-making protocols were codified and consistently applied across the network
- Security practices were aligned with ISO 27001, UK GDPR, and best-in-class data ethics
- The consortium was positioned to respond confidently to regulatory, press, or public scrutiny
- Reputational risk was reduced without compromising operational value

“We brought Jonathan in at a critical point. His ability to embed robust security controls without blocking operations was exactly what we needed. The platform’s never felt more defensible — or more useful.”

Insights & Takeaways
- Shared intelligence platforms demand shared accountability — and consistent application of standards.
- Legal, operational, and technical functions must collaborate to create defensible security models.
- Transparency is a security enabler, not a burden, when embedded in day-to-day operations.
- Security maturity doesn’t come from technology alone — governance, process, and clarity matter more.
What’s Next
The consortium continues to evolve its fraud intelligence programme, with Muse supporting as a trusted advisor. Plans are underway to introduce federated access models and expand membership, underpinned by the same principles of secure, defensible, and ethical data use.
