Summary
The authors explain that bringing new Software-as-a-Service (SaaS) tools into large companies is complicated because many security and risk checks happen separately and cause delays or mistakes. They created a step-by-step framework that connects different areas like risk management, cybersecurity, access control, and disaster recovery into one smooth process. Their approach helps avoid repeated efforts, clarifies who is responsible, and improves safety when using SaaS. They also provide practical advice and a checklist based on real-world experiences to help companies onboard SaaS more efficiently and securely.

Abstract
As enterprises increasingly adopt Software-as-a-Service (SaaS) platforms for mission-critical functions, onboarding these services has emerged as a complex challenge extending well beyond procurement and basic security review. In regulated environments, SaaS onboarding must address multiple interdependent control domains, including Third-Party Risk Management (TPRM), cybersecurity assessment, Identity and Access Management (IAM), and disaster recovery (DR), which are often executed in isolation, resulting in delayed go-lives, duplicated assessments, unclear ownership, and residual operational risk. This paper proposes a control-driven, end-to-end SaaS onboarding framework that integrates TPRM, cybersecurity, IAM, and DR into a unified lifecycle model. The framework introduces a stage-based approach spanning intake and risk scoping, architecture validation, identity design, resilience assessment, and post-production governance. Key contributions include: (1) a structured SaaS onboarding lifecycle emphasizing sequencing and dependency management across control domains; (2) a cross-domain control mapping highlighting failure modes caused by siloed reviews; and (3) practical design patterns for secure connectivity, federated identity, least-privilege access, and shared-responsibility disaster recovery. Supported by operational lessons from enterprise-scale implementations and a reference governance checklist, the framework helps organizations reduce onboarding friction, improve auditability, and strengthen the security and resilience posture of SaaS-enabled platforms.
