Scalable Zero-Trust Architectures for Enhancing Security in Multi-Cloud SaaS Platforms

Abstract

The recent advancement in cloud computing technology has led organizations to embrace multi-cloud systems, wherein they utilize services from many cloud service providers. The increasing reliance on Software as a Service (SaaS) platforms across multiple cloud environments has underscored the need for robust security frameworks that can effectively address contemporary cyber threats. This review paper explores the scalable Zero-Trust Architectures (ZTA) as a vital security measure for multi-cloud SaaS platforms. By advocating a security paradigm that assumes no implicit trust, regardless of network location, ZTA provides a framework for continuous verification of users and devices accessing sensitive resources. We examine a number of ZTA architectural components, including micro-segmentation, identity and access management, and real-time threat detection. Furthermore, we emphasise the importance of ZTA in improving data security, compliance, and overall resilience against complex assaults, as well as the difficulties and advantages of integrating ZTA within multi-cloud environments. The analysis indicate that a scalable Zero-Trust approach can significantly improve security posture while maintaining operational efficiency across diverse cloud infrastructures
