Evaluating Cloud Security Posture Management in Fintech Microservices

Abstract

Fintech platforms increasingly rely on cloud native microservices architectures to deliver scalable, resilient, and feature rich financial services. While microservices enable rapid innovation and independent deployment, they also introduce a highly dynamic and complex security landscape characterized by ephemeral workloads, extensive api exposure, and continuous configuration change. In regulated fintech environments, misconfigurations within cloud infrastructure and services represent one of the most prevalent and impactful sources of security risk. Cloud security posture management (cspm) has emerged as a critical capability for identifying, monitoring, and remediating cloud misconfigurations at scale. This paper evaluates the role, effectiveness, and limitations of cspm in securing fintech microservices architectures. Through architectural analysis, control mapping, and expert-informed evaluation, the study examines how cspm tools contribute to continuous security assurance, regulatory compliance, and operational resilience. The findings demonstrate that cspm significantly improves visibility into configuration risk, reduces exposure windows, and strengthens governance when integrated into devsecops workflows. However, the study also identifies challenges related to context awareness, alert prioritization, and microservice-level granularity. The paper positions cspm as a foundational—but not standalone— component of cloud security strategy for fintech microservices.
