Software as a service (SaaS) and other contemporary applications rely on the scalable, on-demand resources made possible by cloud computing, which has changed the way computer services are delivered. SaaS provides numerous benefits; in particular, it is cheaper, easy to use and readily scalable, but it also means large risks because its construction is multi-tenant and based on cloud technologies. These risks encompass data theft, unauthorised access, identity threats as well as compliance concerns, all of which translate to potential hefty monetary and brand losses. The following paper aims to explore the historical development of and the security issues surrounding cloud computing with an emphasis on SaaS. Major security issues, for instance, data separation, network insecurity, and web application risks are described using examples. Moreover, the paper defines the guidelines for the secure SaaS model and such pillars as encryption, access control, IAM, security audits, and security incidents management. By integrating these strategies, organisations can mitigate security risks, ensure compliance with regulatory standards, and maintain user trust while leveraging the full potential of SaaS applications.
