Enterprise Data Security Architecture at Global Financial Infrastructure
The Challenge
A global post-trade financial market infrastructure organization processing trillions in daily settlements required enterprise-scale data security with integrated identity, traffic steering, segmentation, and telemetry across a complex multi-cloud environment.
What I Was Asked to Do
Design and implement control-plane/data-plane integration patterns, establish platform reliability standards, and own end-to-end Zscaler and DLP stack operations.
How I Approached It
Architected multi-layer secure access and inspection framework with SLO-style performance baselines, alerting thresholds, and escalation paths. Built SIEM/SOAR integration pipelines with standardized event fields and operational dashboards. Created runbooks and reference architectures enabling consistent outcomes across support shifts. Implemented RCA processes to eliminate root causes of recurring incidents.
The Outcome
Delivered enterprise-scale data security program protecting critical financial infrastructure. Improved triage speed and audit readiness across the organization. Established preventive controls reducing repeat incident rates and maintaining continuous compliance posture.
