Artificial intelligence is quickly becoming part of everyday work. Employees use AI tools to write emails, summarize documents, create presentations, analyze data, write code, and troubleshoot technical problems.

However, there is a growing security concern behind this productivity boost: Shadow AI.

Shadow AI refers to the use of AI tools or AI features by employees without the knowledge, approval, or governance of the organization's IT or security team.

The problem is not necessarily that employees are using AI. Instead, the problem is that IT may not know what tools are being used, what information is being shared, or how that information is being handled.

Shadow AI is similar to the idea of Shadow IT.

In traditional Shadow IT, employees might install unauthorized applications or use cloud services without informing IT.

With Shadow AI, employees may use public AI services, browser extensions, coding assistants, or AI-powered applications without going through the organization's security and approval process.

For example, an employee might copy a customer complaint into a public AI chatbot and ask:

"Summarize this and write a professional response."

The employee may only see this as a productivity shortcut. However, from a security perspective, company or customer information has now been sent to an external AI service.

That is where the risk begins.What Is Shadow AI?

Why Is Shadow AI a Security Problem?

The biggest concern is data exposure.

Employees may unknowingly provide AI tools with:

• Customer information

• Internal documents

• Source code

• Network configurations

• Credentials or API keys

• Financial information

• Business strategies

• Personally identifiable information (PII)

Consequently, an organization may lose visibility over where sensitive information is being processed.

NIST's AI Risk Management Framework specifically highlights information security and privacy as risks organizations should consider when adopting generative AI.

A Simple Example

Imagine a network administrator is troubleshooting a firewall issue.

They copy a configuration containing:

Firewall IP addresses
Public IP addresses
VPN configuration
Internal network information
Usernames

They then paste the configuration into an online AI tool and ask it to identify the problem.

The AI may provide a very useful answer.

However, the administrator may have unintentionally shared sensitive infrastructure information with an external service.

The technical problem may have been solved, but a security problem may have been created.

Shadow AI Is Not Always an "Unknown AI App"

This is an important distinction.

Organizations may approve a productivity application, but that application can later introduce new AI capabilities.

Therefore, simply maintaining a list of approved applications may not be enough.

Recent security discussions are increasingly focused on how employees interact with AI features, rather than only whether the application itself is approved.

For example:

Approved Application
        ↓
New AI Feature
        ↓
Employee Uses AI
        ↓
Sensitive Data Shared
        ↓
Security Team Has No Visibility

As a result, organizations need to think about AI usage and data handling, not just application approval.

Shadow AI and AI-Generated Code

Another growing concern is AI-assisted coding.

Developers can use AI tools to generate:

• Scripts

• PowerShell

• Python

• SQL

• Infrastructure-as-code

• Automation

This can significantly improve productivity. However, AI-generated code still needs to be reviewed before being used in production. For example, an employee may ask an AI tool to create a script that disables security controls or handles credentials. The script may work correctly, but it could contain insecure practices.Therefore, AI-generated code should go through the same security review as human-written code.

Should Companies Completely Block AI Tools?

Not necessarily. A complete ban may simply encourage employees to find ways around security controls. Instead, organizations should make secure and approved AI usage easier than unauthorized usage.

For example, companies can provide:

• Approved AI tools

• Clear AI usage policies

• Data classification guidelines

• DLP controls

• Identity-based access

• Logging and monitoring

• Employee security training

As a result, employees can use AI while the organization maintains better visibility and control.

Shadow AI Best Practices

Organizations can reduce Shadow AI risks by following a few practical steps.

1. Create an AI Usage Policy

Clearly explain what employees can and cannot share with AI tools.

2. Provide Approved AI Tools

Instead of simply blocking AI, provide employees with secure alternatives.

3. Protect Sensitive Data

Employees should never paste passwords, API keys, confidential documents, customer data, or sensitive infrastructure information into public AI services.

4. Use DLP and Security Controls

Where appropriate, use Data Loss Prevention (DLP), endpoint controls, web filtering, and identity policies to detect and prevent inappropriate data sharing.

5. Monitor AI Usage

Security teams should understand which AI services are being accessed and how they are being used.

6. Train Employees

Most Shadow AI incidents may start with a simple misunderstanding rather than malicious intent.

Therefore, employees should understand what information is safe to share and what should remain inside the organization.

7. Review AI Tools Regularly

AI capabilities change quickly. Consequently, an application that was considered low-risk yesterday may introduce new AI functionality tomorrow.

Organizations should therefore review AI usage and security policies regularly.

Shadow AI: The Goal Is Control, Not a Ban

AI can provide significant productivity benefits.

Therefore, the objective should not simply be to prevent employees from using AI.

Instead, organizations should create a controlled environment where employees can use approved AI tools while protecting sensitive information.

Think of it this way:

Uncontrolled AI → Shadow AI → Low visibility → Higher risk

Whereas:

Approved AI → Clear policies → Monitoring → Controlled adoption

Final Thoughts

Shadow AI is becoming an important cybersecurity and governance challenge as organizations adopt AI faster than traditional IT policies can adapt.

However, the solution isn't necessarily to block everything.

Organizations should focus on visibility, data protection, identity, access control, employee awareness, and clear AI governance.

Most importantly, employees need to understand that AI tools should be treated like any other external service: don't share sensitive information unless your organization has approved the service and understands how that data is handled.

AI can be a powerful productivity tool. Nevertheless, without proper governance, that same productivity can introduce a new security risk.

The goal isn't to stop employees from using AI. The goal is to make sure they can use it safely.
