Banking Data Security
A zero-trust, Azure-native security overhaul that closed the gaps left by aging on-prem infrastructure — and gave a regulated financial institution a defensible posture for the next decade.
At a glanceSaving a Large Financial Institution by Securing Their Data Through the Cloud
Legacy infrastructure was leaving sensitive customer data exposed at exactly the moment cyber threats and regulators were tightening the screws.
- Zero-trust architecture established across the entire estate.
- Customer data encrypted at rest and in transit, end to end.
- Compliance audits passed first time, with documented controls.
The ChallengeWhat stood in the way
When a large financial institution came to Data Integrity Services, the situation was urgent. Their on-premises infrastructure had served them well for years, but it was no longer keeping pace with the threat landscape. Attack surfaces were expanding, sensitive customer data was sitting in systems that predated modern security practices, and regulators were beginning to ask harder questions. A single breach would mean reputational damage, regulatory penalties, and a loss of customer trust that no marketing budget could fix. The institution needed more than perimeter patching — it needed a fundamentally different security model, designed for a world where every request must be verified and every byte must be protected.
Our ApproachHow DIS got to work
DIS led a cloud-anchored security overhaul: a zero-trust architecture on Microsoft Azure with identity-driven access, continuous threat detection, and encryption woven into every layer.
- Mapped sensitive data, classified it, and built encryption controls around the highest-risk stores.
- Adopted a zero-trust model with identity-driven access using Microsoft Entra ID.
- Deployed Microsoft Defender for Cloud for continuous threat detection across the estate.
- Codified compliance controls so every audit can be evidenced from a single source of truth.
Data security isn't a project — it's an architecture. DIS gave us one we can defend, audit, and build on for the next decade of regulatory change.
Our SolutionThe result we delivered
The institution now operates from a defensible, modern security baseline. Threats are detected in real time, sensitive data is unreadable to anyone outside the trust boundary, and audits no longer require a months-long scramble for evidence.
- Continuous monitoring and automated response to suspicious activity.
- Granular, identity-aware access control for every system and dataset.
- Customer financial data fully encrypted at rest and in transit.
- Audit-ready evidence available on demand, not gathered after the fact.
