What is Shadow SaaS? Risks & Best Practices

What is Shadow SaaS?

‍

Shadow SaaS refers to employees using unauthorized SaaS applications within a company. These SaaS apps are typically adopted without approval or oversight from the IT or security teams. While these apps may help employees boost productivity, they operate outside formal IT control, leading to potential security risks and compliance issues.

‍

What Causes Shadow SaaS?

‍

Shadow SaaS arises for several reasons, often because employees or departments seek tools to improve productivity without formal IT approval. More specifically:

‍

Causes	Description
Employee-Driven Adoption	Employees adopt familiar, easy-to-access tools to improve efficiency without IT approval. While this self-service approach speeds up workflows, it bypasses security protocols, increasing risks like data leaks and unauthorized access.
Lack of IT Oversight	When IT departments fail to closely monitor software usage, unauthorized SaaS apps can proliferate across the organization. Using tools like Shadow IT discovery can help companies identify and monitor unsanctioned apps.
Departmental Flexibility Needs	Some departments need specialized tools to meet their specific goals quickly. If IT’s procurement processes are slow, teams may adopt shadow SaaS solutions, sacrificing compliance and security for speed and efficiency.
Speed vs. Compliance	Teams often prioritize speed and quick results over compliance, adopting unvetted cloud apps that introduce security risks. This approach can lead to regulatory breaches, fines, and long-term security vulnerabilities.

Shadow SaaS Risks and Challenges

‍

Shadow SaaS presents significant challenges for companies by introducing security and compliance risks and governance issues. Addressing these risks is essential to maintaining a secure IT environment.

‍

1. Security Risks

‍

Since unauthorized apps bypass the IT department, sensitive data might be exposed to external threats, increasing the chance of data breaches and unauthorized access. Additionally, former employees may retain access to these apps after leaving the company, heightening the risk of data leaks or misuse of sensitive information.

‍

2. Compliance Risks

‍

The unauthorized tools may not comply with industry regulations such as GDPR or HIPAA, leading to legal issues. The lack of compliance oversight in shadow SaaS can expose the organization to penalties, especially if sensitive data is processed without proper security protocols.

‍

3. Data Privacy and Integrity Threats

‍

Since IT and security teams are unaware of unauthorized tools, sensitive company data could be transferred through unsecured channels, risking exposure. This lack of control can lead to data integrity threats, where unverified applications cause inaccuracies or corruption in the data.

‍

4. Integration Challenges

‍

Unapproved SaaS apps may not align with the company’s IT systems, creating inefficiencies and potential security loopholes. Integration challenges make it difficult for security teams to maintain a cohesive digital ecosystem, further complicating IT management efforts.

‍

5. Governance and Control Challenges

‍

IT departments lose the ability to enforce control over the applications employees use, leading to a breakdown in governance. This lack of oversight complicates the ability to monitor app usage, manage updates, and enforce security measures across all platforms.

‍

6. Increased IT Complexity

‍

By introducing unauthorized tools, departments add layers of unpredictability, making it harder to manage resources effectively. The result is increased IT complexity, where security teams and administrators struggle to maintain oversight over all digital assets.

‍

7. Potential Cost Implications

‍

Unmonitored apps can lead to hidden subscription costs or redundant tools, straining the organization’s budget. Without a clear understanding of what apps are in use, companies may end up paying for unnecessary or duplicative services.

‍

How to Identify Shadow SaaS in Your Organization

‍

Identifying shadow SaaS requires a multi-layered approach that balances technology and employee engagement. To fully understand the scope of unauthorized SaaS applications within your organization, security teams should implement a combination of discovery methods and continuous monitoring.

‍

Strategies	How to Implement	Ideal Outcome
Use Network Traffic Analysis	Implement network monitoring tools to detect unusual data flows to unauthorized SaaS apps.	Early detection of unsanctioned SaaS apps, minimizing potential security risks.
Employee Engagement and Feedback	Survey employees to understand why they use unapproved apps and identify essential tools for productivity.	Insights into workforce needs, leading to better alignment of IT-approved tools with user requirements.
Conduct Regular Security Audits	Schedule periodic security audits to review all SaaS applications, compare usage with policies, and detect anomalies.	Enhanced compliance and alignment between departments, reducing the risk of unapproved tools being overlooked.
