Shadow IT in SaaS refers to the use of unauthorized or unsanctioned SaaS applications within an organization, without the approval or oversight of an organization's IT or security teams. Employees and departments often adopt these tools independently to enhance productivity, but their use creates security risks, compliance challenges, and governance gaps. Without proper management, shadow IT expands an organization's attack surface, making it difficult to enforce security policies and protect sensitive data..
Causes of Shadow SaaS Adoption
Shadow SaaS arises for several reasons, primarily driven by the need for efficiency and flexibility. Key causes include:
- Employee-Driven Adoption: Employees seek familiar, easy-to-use tools to streamline their workflows without waiting for IT approval. While this accelerates productivity, it bypasses security protocols and increases risks like data leaks and unauthorized access.
- Departmental Needs: Different teams may require specialized applications to meet their objectives quickly. If IT’s procurement processes are slow, departments may adopt SaaS solutions independently, sacrificing security for speed and functionality.
- Lack of IT Oversight: When IT departments do not actively monitor software usage, unauthorized and unchecked SaaS applications can proliferate. This lack of visibility makes it difficult to enforce security policies and prevent data exposure.
- Speed vs. Security Policy Compliance: Many teams prioritize speed and agility over compliance and security. In doing so, they may introduce SaaS applications that do not align with corporate security standards, leading to regulatory and data protection challenges.
Risks of Shadow IT in SaaS
Shadow IT poses several risks to an organization’s security and compliance posture, including:
Security Risks
Unsanctioned applications may lack proper security controls, exposing sensitive data to breaches.
Sensitive Data Exposure Due to GenAI Adoption
Employees frequently adopt generative AI tools, such as ChatGPT, Grammarly, and DeepSeek, without IT oversight. These tools process sensitive company data, creating compliance and privacy risks. Studies indicate that between 31% and 38% of AI-using employees enter sensitive work data into AI tools, increasing exposure risks.
SaaS Sprawl and Redundancies
Without centralized governance, organizations may accumulate overlapping or unnecessary applications, increasing costs and inefficiencies.
Identity and Access Risks
SaaS applications outside corporate IdP (identity provider) management create unmanaged identities, increasing the likelihood of orphaned accounts and unauthorized access.
Compliance Violations
Unauthorized SaaS tools may not meet industry regulations and standards like GDPR, HIPAA, ISO, or SOC 2, leading to potential fines or legal consequences.
Data Governance Issues
IT and security teams lose visibility and control over where company data is stored, shared, and accessed.
Addressing Shadow IT Risks in SaaS
To mitigate the risks associated with shadow IT, organizations should:
- Implement SaaS Discovery Tools: Gain visibility into all SaaS applications, both sanctioned and unsanctioned, including non-SSO-connected apps and accounts.
- Monitor and Control Access: Ensure all SaaS applications follow corporate authentication policies and governance frameworks.
- Enforce Security Policies: Establish clear security guidelines and approval workflows for SaaS adoption.
- Monitor User Behavior: Continuously assess SaaS usage to detect unauthorized or risky applications.
- Identity and Access Management (IAM): Strengthen IAM controls by enforcing single sign-on (SSO) and multi-factor authentication (MFA) for all applications.
- Assess and Sanction Necessary Applications: Identify critical shadow SaaS applications and bring them under IT governance while removing unnecessary or risky apps.
- Educate Employees: Promote awareness of shadow IT risks and encourage employees to use approved applications.
Frequently Asked Questions
What does the term "shadow IT" mean?
Shadow IT refers to the use of information technology systems, devices, software, and applications without explicit approval from an organization’s IT or security team. This includes unsanctioned SaaS applications, personal cloud storage, and unapproved collaboration tools.
Is shadow IT a threat?
Yes, shadow IT poses security, compliance, and operational risks to organizations. It can lead to data breaches, regulatory violations, and identity management challenges due to a lack of oversight and security controls.
What is shadow IT in Microsoft 365?
Shadow IT in Microsoft 365 refers to employees using unauthorized third-party SaaS applications or services that integrate with Microsoft 365. These integrations may bypass corporate security policies, leading to potential data security and compliance risks.
What is a shadow IT policy?
A shadow IT policy is a set of guidelines that organizations implement to manage and control unauthorized software and application usage. It typically includes approved application lists, security controls, access management policies, and employee training to reduce shadow IT risks.
How does shadow IT affect compliance?
Shadow IT can lead to non-compliance with regulations like GDPR, HIPAA, and SOC 2 if unauthorized applications process sensitive data without proper security measures. Lack of oversight can result in fines, legal issues, and reputational damage.
What is the difference between Shadow IT and Shadow SaaS?
Shadow IT is a broad term that encompasses any technology used without IT approval, including hardware, software, and cloud services. Shadow SaaS refers specifically to unsanctioned cloud applications adopted by employees or teams without IT oversight.
What should companies do when they discover Shadow SaaS applications?
Companies should assess the security risks of each application, integrate essential tools into IT governance, revoke access to unnecessary or risky apps, and educate employees on approved alternatives.
