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. Many employees in most organizations use shadow IT, often turning to productivity apps and external applications to meet their needs when official tools are seen as inadequate or slow to deploy.
Employees and departments often adopt these tools independently to enhance productivity, but the widespread adoption of cloud based services has contributed to app sprawl and system inefficiencies. Their use creates security risks, compliance challenges, and governance gaps. Shadow IT is rarely malicious and often driven by the need for quick and flexible access to tools; there are also benefits of shadow IT, such as increased agility and access to innovative tools. Without proper management, shadow IT expands an organization’s attack surface, making it difficult to enforce security policies and protect sensitive data.
Introduction to Shadow IT
Shadow IT describes the use of information technology systems, software, devices, or services within an organization without the explicit approval or awareness of the IT department. This growing trend has accelerated with the widespread adoption of cloud services and the increasing need for remote access to business applications. As employees seek out tools that help them work more efficiently, they may inadvertently introduce significant security risks, including data breaches, security gaps, and compliance issues. For organizations, understanding the scope and impact of shadow IT is essential to maintaining a secure and compliant technology environment.
Causes of Shadow SaaS Adoption and the IT Department
Shadow SaaS arises due to several factors, primarily driven by the need for efficiency and flexibility. Key causes include:
- Employee-Driven Adoption: Individual employees often seek familiar, easy-to-use tools to streamline their workflows and pursue faster solutions 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 business units may require specialized applications to meet their objectives quickly. If IT’s procurement processes are slow, departments may make technology purchases and adopt SaaS solutions independently, sacrificing security for speed and functionality.
- Lack of IT Oversight: When IT teams do not actively monitor software usage, unauthorized and unchecked SaaS applications can proliferate. This lack of visibility means the IT team loses control, making 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.
Many organizations face these challenges as new cloud services and cloud resources proliferate across the enterprise. Personal devices and mobile devices are commonly used for shadow IT, further complicating management and security.
While shadow SaaS can enable teams to work more efficiently and autonomously, it also introduces potential risks and other risks, such as security threats, compliance issues, and data breaches.
Examples of Shadow IT in SaaS
A common manifestation of shadow IT is the use of SaaS applications that have not been vetted or approved by the IT department. For instance, employees might use cloud storage platforms like Dropbox or Google Drive to share files, project management tools such as Trello or Asana to organize tasks, or messaging apps like Slack for team communication. While these tools can enhance collaboration and productivity, they also introduce significant security risks. Without proper oversight, sensitive corporate data may be stored or transmitted through these unsanctioned channels, increasing the likelihood of data breaches and compliance issues. To safeguard sensitive information, organizations must proactively identify shadow SaaS usage and monitor how these applications interact with their corporate network.
Benefits and Advantages of Shadow IT
Despite the significant security risks associated with shadow IT, there are notable benefits that drive its adoption. Employees often turn to unsanctioned tools for faster access to the resources they need, enabling them to respond quickly to business challenges and improve overall productivity. Shadow IT can also foster innovation, as teams experiment with new solutions that may not yet be available through official channels. This agility allows organizations to stay competitive and adapt to changing market demands. However, to fully realize these advantages without exposing the business to significant security risks, it is crucial to provide employees with approved, secure alternatives that deliver the same speed and flexibility.
Security Risks of Shadow IT in SaaS
Shadow IT poses several risks to an organization’s security and compliance posture, including:
Security Risks
Unsanctioned applications and unauthorized tools may lack proper security controls, exposing sensitive data to breaches and increasing cloud security vulnerabilities. Shadow assets, such as unapproved cloud services, can serve as entry points for cybercriminals.
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, compliance failures, or legal consequences. The absence of robust compliance protocols further increases the risk of regulatory penalties and investigations.
Data Governance Issues
IT and security teams lose visibility and control over where company data is stored, shared, and accessed, resulting in data management challenges and fragmented oversight.
Data Exfiltration and Theft
Shadow assets and unauthorized tools can facilitate data exfiltration, leading to data theft and exposure of proprietary information. This increases the risk of sensitive or proprietary information being stolen or leaked outside the organization.
File Sharing Risks
The use of unapproved file sharing services can result in data breaches, data leakage, and compliance issues, as these platforms are often unmonitored and lack proper security controls.
Business Purposes Risks
Using shadow IT for business purposes can threaten compliance with legal and regulatory standards, exposing organizations to regulatory and legal consequences if communication platforms or IT resources are misused or lack oversight.
Compliance and Regulatory Issues
Shadow IT can create serious compliance and regulatory challenges for organizations, particularly when it comes to protecting sensitive corporate data. The use of unauthorized applications increases the risk of data breaches and may result in non-compliance with industry regulations such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), and the Payment Card Industry Data Security Standard (PCI DSS). These regulations require strict controls over how personal and sensitive data is processed and stored. When shadow IT solutions are implemented without proper oversight, organizations may inadvertently violate these standards, leading to legal penalties and reputational damage. Proactively managing shadow IT is essential to ensure compliance and safeguard sensitive information.
Data Protection and Shadow IT
Protecting sensitive data is a top priority in the face of shadow IT. The use of unsanctioned devices, cloud based applications, and external services can expose organizations to data breaches, data loss, and unauthorized access to confidential information. To address these risks, organizations should implement robust access controls, encrypt sensitive data, and deploy data loss prevention solutions. Regular audits and continuous monitoring are also critical to identify shadow IT assets and ensure that all data stored and shared within the organization complies with security protocols and regulatory requirements. By prioritizing data protection and taking proactive steps to manage shadow IT, organizations can minimize the risk of data compromise and maintain the integrity of their sensitive data.
Addressing Shadow IT Risks and Data Breaches 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. Implement shadow IT discovery and management solutions to identify and address unauthorized cloud resources.
- 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. Collaborate with business units to ensure effective communication and adoption of security policies tailored to their specific needs.
- Prevent Shadow IT: Implement proactive strategies such as regular audits, enhanced visibility, and the use of detection tools to prevent shadow IT and minimize unauthorized IT usage across business units.
