Securing SaaS Access: Navigating the Challenges of Unmanaged Applications
Ever feel like achieving SaaS security puts you between a rock and a hard place?
SaaS applications support many facets of modern business operations, yet these services often lie beyond traditional security perimeters, complicating user management and access control. The decentralized acquisition of SaaS, where employees independently subscribe to SaaS tools without IT oversight (AKA shadow SaaS), compounds the problem and increases an organization’s attack surface. Get used to shadow SaaS and the business-led IT movement, though—it's growing and here to stay—and that's the rock. The hard place is that despite our best efforts to implement security controls like SSO and MFA, protecting unmanaged SaaS applications remains a significant industry challenge.
So what’s the answer? Let’s explore how to secure SaaS access more effectively, regardless of how the app was acquired.
Limitations of Existing Identity Controls
Both SSO and MFA are highly effective for managing access to known, sanctioned SaaS applications. However, they often miss unmanaged SaaS, creating significant blind spots in an organization's security posture. Unmanaged SaaS results from various scenarios:
Employee-driven SaaS: Call it shadow SaaS or business-led IT, the outcome is the same: an app acquired outside of IT’s visibility. According to Gartner, we should expect this trend to continue at an accelerated pace.
SaaS churn: SaaS is easily acquired, and it’s also quickly retired for something else. Many SaaS apps have short lifecycles, estimated at a 40-50% churn rate per year. Because of the high churn rate, many apps remain unfederated.
Smaller SaaS user bases: While enterprise-level SaaS applications like Slack, Zoom, and Salesforce are typically managed through conventional procurement and IT processes, many SaaS applications are smaller, with fewer than ten users. According to various studies, these smaller applications account for 74% of all apps. Due to the smaller user bases, it’s challenging to 1) identify the apps in the first place and 2) monitor logins, manage credentials, and identify unauthorized account sharing. ?
Varied SaaS usage: Employees use SaaS applications differently, leading to actions misaligned with their roles or permissions. Secure SaaS access is not one-size-fits-all; usage variance makes it difficult to standardize access controls across the organization without the input of stakeholders.
In short, securing a diverse and dispersed SaaS environment is complex, complicating the decision of which applications should be prioritized for MFA implementation or integrated into SSO for enhanced SaaS access.
The Risks of Unmanaged SaaS Access
Beyond the immediate security risks and potential for data breaches, unmanaged SaaS access undermines data governance and accountability, making it difficult for organizations to ensure that sensitive information is handled according to mandated standards. Compliance requirements are increasing surrounding MFA requirements, specifically: ?
PCI DSS 4.0: By March 2025, PCI DSS 4.0 will require more robust authentication controls, emphasizing MFA.
NYDFS Cybersecurity Regulation: NYDFS requires MFA for individuals accessing sensitive company information, including SaaS.
HIPAA: HIPAA has long required MFA to access electronic health records (EHRs) and other sensitive healthcare data.

Updated Safeguards Rule: In addition to mandating financial institutions to review access controls periodically and maintain a SaaS inventory, MFA is required for anyone accessing customer information on your system.
As the requirements for MFA and access controls expand across various standards, effective SaaS access management is essential—and a more practical approach for prioritizing SaaS for MFA and SSO is needed, too. The good news is that Grip can meet these demands while enhancing your overall SaaS security.
