SaaS adoption creates visibility gaps and security risks for enterprises

The rapid expansion of Software-as-a-Service (SaaS) adoption is creating significant visibility gaps and security risks for enterprises. As organizations continuously add applications, services, and data stores, they face a growing problem of SaaS sprawl and cloud complexity.

Fortinet’s 2026 Cloud Security Report indicates that 69% of organizations identify tool sprawl and visibility gaps as primary barriers to effective cloud security. This fragmentation forces IT teams to manually correlate information across disconnected systems, creating a heavy operational burden. Experts suggest that organizations must view their SaaS environment as an interconnected ecosystem rather than a simple list of applications to better manage shadow SaaS and redundant tools.

Furthermore, the integration of various SaaS products through APIs, OAuth tokens, and automated workflows introduces hidden vulnerabilities. These connections can create invisible dependencies and persistent access pathways into sensitive systems if not properly governed. Security professionals emphasize that security should be treated as a design principle built into the architecture from the beginning, rather than a post-launch patch, to prevent breaches caused by abused vendor connections or poorly managed machine-to-machine connectors.
