Enterprise Resource Planning (ERP) systems provide substantial benefits for organizations of all sizes through integrated data sharing and improved efficiency across departments. The combination of ERP with cloud computing further enhances scalability, reliability, and cost efficiency, yet it introduces critical security challenges that organizations cannot ignore. This article presents a systematic review that evaluates both the advantages and the security concerns linked to the implementation of ERP in cloud environments. The review demonstrates that while such systems improve operational flexibility, reduce infrastructure costs, and expand accessibility, they also raise recurring issues relating to confidentiality, integrity, and compliance. The findings highlight that although cloud ERP adoption can deliver transformative benefits, unresolved security concerns demand careful mitigation through well defined strategies and industry best practices.
