Abstract: Cloud computing has become a foundational infrastructure for modern digital services, enabling scalable storage, computation, and collaboration across sectors. Despite its operational benefits, cloud adoption raises persistent concerns related to security, privacy, and trust, particularly as sensitive data and critical workloads migrate to third-party environments. This article examines the multifaceted challenges associated with managing cloud security, emphasizing data confidentiality, integrity, availability, regulatory compliance, and user trust. It analyzes evolving threat vectors such as data breaches, insider threats, insecure application programming interfaces, misconfigurations, and advanced persistent attacks that exploit shared cloud architectures. The research further explores how jurisdictional issues, multi-tenancy, and limited visibility complicate governance and accountability in cloud ecosystems. To address these challenges, the paper reviews contemporary security solutions, including encryption mechanisms, identity and access management, zero-trust architectures, continuous monitoring, and security-as-a-service models. Particular attention is given to privacy-preserving techniques, such as data anonymization and homomorphic encryption, alongside compliance-driven frameworks aligned with global data protection regulations. The article also highlights the role of organizational policies, shared responsibility models, and risk-based security planning in strengthening trust between cloud service providers and consumers. By synthesizing technical, organizational, and regulatory perspectives, this work provides a structured understanding of how cloud security strategies can evolve to meet emerging risks. The findings underscore that achieving sustainable privacy and trust in cloud environments requires not only advanced technical controls but also transparent governance, continuous risk assessment, and collaboration among stakeholders. This review aims to support researchers, practitioners, and decision-makers in developing resilient cloud security approaches that balance innovation with robust protection of digital assets. It further encourages alignment between technological innovation and ethical responsibility to ensure that cloud ecosystems remain secure, compliant, and trustworthy while supporting long-term digital transformation, economic growth, and reliable service delivery across diverse organizational and societal contexts globally across critical industry domains.
