Shadow AI: The Hidden Risk Lurking in Your Business Operations

What is Shadow AI?

In the modern enterprise, Artificial Intelligence (AI) is no longer a futuristic concept—it’s embedded in everyday operations. However, alongside its benefits, a silent and growing threat has emerged: Shadow AI.

Shadow AI refers to the unauthorized and unregulated use of AI tools and services by employees or departments without the approval or oversight of the organization’s IT or security teams. It’s the modern version of Shadow IT, but with far more profound implications.

Consider these examples:

• A marketing team uploads sensitive customer data to ChatGPT or Gemini to generate personalized campaigns faster.
• Healthcare researchers use unvetted AI tools for patient data analysis, potentially exposing sensitive health records.
• Financial analysts input proprietary algorithms into external AI platforms to optimize investment strategies, risking intellectual property theft.

What makes Shadow AI especially dangerous is its subtlety—employees may not even realize the security, privacy, and compliance risks they introduce simply by trying to work more efficiently.

The Impact and Risks of Shadow AI on Businesses

Manu risks can arise from the presence of Shadow AI in the companies, however, these are our Top 4 ranking.

1. Data Privacy and Regulatory Non-Compliance

Unauthorized use of AI tools can lead to significant data privacy breaches and regulatory non-compliance.

Real-World Incident:

In May 2023, Samsung engineers inadvertently leaked confidential information by using ChatGPT to review internal code and documents. This incident prompted Samsung to ban the use of generative AI tools across the company to prevent future breaches.

Such incidents highlight the risk of employees sharing sensitive or proprietary data with generative AI platforms without proper oversight, potentially violating data protection regulations like GDPR or HIPAA.

2. Intellectual Property and Trade Secret Exposure

Shadow AI usage can result in the unintended exposure of intellectual property and trade secrets, posing significant risks to companies in technology, manufacturing, and financial services.

Real-World Incident:

Employees at Samsung used ChatGPT to help debug code and optimize workloads, inadvertently submitting sensitive internal data, including proprietary source code, into ChatGPT. This led Samsung to request OpenAI to remove the source code to prevent it from being used in training models.

In manufacturing, similar risks arise when proprietary designs or processes are shared with AI tools lacking proper data handling agreements, potentially leading to competitive disadvantages.

3. Security Vulnerabilities

The integration of AI tools without proper vetting can introduce security vulnerabilities into an organization’s systems.

Real-World Incident:

Researchers discovered critical vulnerabilities in TorchServe, a tool for serving PyTorch models, which could lead to remote code execution and expose thousands of instances, including those belonging to major global organizations.

Such vulnerabilities underscore the importance of thoroughly assessing AI tools for security risks before deployment.

4. Reputational Damage

Misuse of AI tools can lead to reputational harm, especially when AI-generated content is inappropriate or offensive.

Real-World Incident:

In October 2023, Microsoft faced backlash after its AI-generated poll appeared next to a sensitive news article about the death of Lilie James, a 21-year-old water polo coach. The poll, created without the Guardian’s approval, was deemed distressing and harmful to the Guardian’s reputation.

This incident illustrates how AI-generated content, when not properly managed, can damage an organization’s public image.

How to Detect and Monitor Shadow AI in Your Organization

Proactive organizations are now shifting from reaction to prevention and early detection of Shadow AI usage. Here’s how you can start:

1. Monitor AI-Related Domains and Traffic

One of the most practical and cost-effective ways to detect Shadow AI usage is by monitoring DNS queries and outbound network traffic to known AI service domains. This method offers early visibility into whether employees are accessing unsanctioned AI platforms—often before any sensitive data is transmitted.

As most AI tools—such as ChatGPT, Google Gemini, Anthropic’s Claude, or open-source platforms hosted on cloud services—require users to interact via a web interface or API. These interactions generate domain name system (DNS) queries and outbound HTTPS connections that can be tracked using existing security infrastructure.

By maintaining a watchlist of AI-related domains, organizations can:

• Flag and alert on access to unapproved services
• Block access outright for specific roles, departments, or network segments
• Trigger internal reviews when unusual AI usage patterns are detected

Here is a quick and dirty list of common AI domains to monitor

• openai.com (ChatGPT, GPT API access)
• gemini.google.com (Google Gemini)
• claude.ai (Anthropic Claude)
• huggingface.co (open-source models and inference APIs)
• runpod.io, replicate.com, perplexity.ai (AI-as-a-service platforms)
• poe.com (aggregator of multiple AI tools)

2. Leverage Enterprise Security Tools

For larger or cloud-based companies, leveraging existing SASE (Secure Access Service Edge) or CASB (Cloud Access Security Brokers) solutions can provide more granularity and control. Frequently they offer built-in capabilities to detect, monitor, and block unauthorized AI usage. Some examples below (SIEM and XDR solutions can also be used).

Zscaler

Zscaler’s Zero Trust Exchange enables organizations to inspect cloud-bound traffic and apply policies that restrict access to unauthorized AI services.

How it helps: Zscaler can detect when employees attempt to upload data to AI platforms like ChatGPT or Gemini and automatically block the transmission of sensitive information, such as healthcare records or PII. For example, a healthcare provider may use Zscaler to prevent inadvertent patient data uploads to generative AI tools, preserving compliance with HIPAA.

Netskope

Netskope’s Cloud Access Security Broker (CASB) offers deep visibility into cloud application usage, including unapproved AI tools, and can enforce usage policies in real time.

How it helps: Netskope can identify which business units or users are accessing AI services, flag unknown tools, and apply contextual controls to allow, block, or limit their use. For example, a fast-growing tech startup deploys Netskope to detect experimentation with AI tools across teams and ensures all AI usage complies with internal policies.

Cisco Umbrella

Cisco Umbrella delivers DNS-layer protection by monitoring outbound traffic and proactively blocking requests to risky or unauthorized AI domains.

How it helps: By stopping connections to domains like openai.com or bard.google.com at the DNS level, Umbrella prevents employees from using unauthorized AI services—before any data is transmitted. For example, a financial institution uses Umbrella to block unsanctioned access to AI tools, blocking or monitoring outbound traffic to unauthorized AI services helps prevent analysts from exposing proprietary models.

Palo Alto Networks

With Prisma Cloud and Next-Gen Firewalls, Palo Alto Networks provides behavioral analytics and deep inspection of network activity.

How it helps: These tools detect anomalous data flows—such as sudden spikes in outbound traffic or unusual API connections—that may indicate Shadow AI use. For example, a multinational tech firm uses Palo Alto’s platform to alert on abnormal data transfer patterns linked to external AI APIs, enabling early intervention.

Fortinet

FortiGate firewalls, enhanced with AI-driven traffic analytics, can detect patterns that signal unauthorized AI usage.

How it helps: Fortinet identifies non-standard traffic to known AI service endpoints, triggering alerts or blocking access based on pre-set rules. For example, a hospital network employs Fortinet to automatically flag attempts to send clinical research data to unsanctioned AI tools for analysis.

3. Implement Policy and Awareness Programs

While technical controls are critical, governance starts with people. Implement AI Acceptable Use Policies and conduct regular awareness sessions to educate employees about the risks of Shadow AI.

4. Establish AI Governance Committees

An AI Governance Committee can oversee the use of AI technologies across the organization, ensuring that only approved tools aligned with corporate policies and regulatory requirements are used.
