The advent of generative artificial intelligence has sparked an unprecedented revolution in individual productivity. However, this rapid adoption has been accompanied by a phenomenon well known to CIOs: Shadow AI. Much like Shadow IT in its day, employees are adopting tools not approved by the company to boost their efficiency.
But this time, the legal, technical, and reputational risks are magnified. How can organizations regain control without stifling innovation?
Summary
- The Shadow AI phenomenon is widespread and inevitable: nearly 80% of employees are already using Shadow AI to streamline their daily tasks.
- The danger lies in the data: the risk of intellectual property and personal data leaking into public models is real and immediate.
- Bans are counterproductive: they erode trust, stifle innovation, and drive users toward even less secure solutions.
- The solution is agile governance: mapping usage patterns, assessing risks by use case, and providing secure, managed enterprise alternatives.

From Shadow IT to Shadow AI: The Story of a Recurring Pattern
Shadow AI is not a behavioral anomaly; it is a symptom of a business need that is not being met by official tools.
In the 2010s, the rise of SaaS (Software as a Service) led employees to use their own cloud storage tools (such as Dropbox) or project management tools (such as Trello) to circumvent internal processes they considered too rigid. It was the golden age of Shadow IT.
Today, the same psychological mechanism is at work with generative artificial intelligence, but on a much larger scale and at a much faster pace.
According to the study Microsoft and LinkedIn’s Work Trend Index (2024), 78% of AI users bring their own tools to the workplace (the “BYOAI”—Bring Your Own AI—phenomenon). Faced with an IT department that is sometimes perceived as a control center rather than a hub of innovation, employees choose immediate efficiency at the expense of compliance and overall security.

Why Shadow AI Is Much More Dangerous Than Shadow IT
While the driving force behind Shadow AI is the same as that of Shadow IT, its technical and strategic implications are of an entirely different nature. The risks are no longer limited to data hosting; they affect the very nature of machine learning models and human biases associated with :
-
Data Leakage:
This is the major risk associated with Shadow AI. Feeding a public LLM (Large Language Model) with corporate data (source code, financial reports, identifiable customer data) exposes the organization to massive data leaks. This data can be used by third-party providers to retrain their public models, effectively breaching trade secrets and violating strict regulations such as the GDPR or the European AI Act. -
The lightning-fast pace of adoption:
AI tools have been adopted in a matter of weeks, whereas SaaS took years to gain traction. Organizations are facing an exponential adoption curve that outpaces traditional IT governance cycles. -
The risk of misinformation and hallucinations:
The uncontrolled use of generative AI tools prone to “hallucinations” (the generation of false facts presented as true) can lead to strategic decision-making based on false data, without any technical safeguards having validated the AI’s output.

How to Manage Shadow AI? The 3-Step iQo Method
To address this wave of Shadow AI, burying our heads in the sand or outright bans are doomed to fail. Blocking access to LLMs only drives usage toward solutions that are even harder to audit (such as the use of personal smartphones).
We recommend a pragmatic, agile, three-step approach to regaining control.
1. Map out Shadow AI to identify actual needs
Before enacting legislation, it is important to understand the reality on the ground. Organizations must analyze network traffic and conduct anonymous, supportive internal surveys. The goal is to identify which tools (ChatGPT, Claude, Midjourney, v0, Copilot, etc.) are actually being used and for what purposes.
Shadow AI is a goldmine of information: it pinpoints the operational pain points where your employees waste time on a daily basis.
2. Classify uses by risk level
All AI use cases do not all pose the same level of risk. A clear risk matrix should be established to guide employees:
-
Low risk:
Translation of public documents, brainstorming of general concepts, drafting of standard email templates. -
Moderate risk:
Compilation of non-confidential internal reports; creation of illustrative images for internal use. -
Critical risk (prohibited outside a secure environment):
Analysis of customer databases (GDPR), submission of proprietary computer code, and drafting of strategic documents related to mergers and acquisitions or patents.
3. Offer approved corporate alternatives
The only effective way to neutralize Shadow AI is to offer an official, secure, and equally effective alternative.
If your employees are using external tools without authorization, provide them with access to a secure enterprise instance (for example, through Azure OpenAI, private APIs, or locally hosted open-source LLMs).
In these controlled environments, the data is strictly isolated, and the publisher is contractually obligated not to reuse it for training its models.
To address this wave of Shadow AI, burying our heads in the sand or outright bans are doomed to fail. Blocking access to LLMs only drives usage toward solutions that are even harder to audit (such as the use of personal smartphones).
Shadow AI: A Powerful Opportunity for the IT Department
Beyond the challenges of cybersecurity, Shadow AI raises a fundamental question about organizations’ digital maturity and agility. If your employees are taking risks to use AI, it’s because they see immediate and measurable value in it.
Shadow AI should not be viewed solely as a cybersecurity threat, but rather as an indicator of productivity. It clearly identifies the company’s top transformation priorities.
A modern IT department must position itself as a business enabler. By overseeing “Shadow AI,” it can transform these clandestine and isolated initiatives into secure, scalable enterprise projects that create shared value.

Frequently Asked Questions
What is Shadow AI?
Shadow AI refers to the use of artificial intelligence tools by employees without corporate approval, governance, or oversight. Examples include the use of ChatGPT, Claude, or other generative AI models with work-related data outside the framework defined by the IT department or management.
What are the main risks of Shadow AI?
Shadow AI exposes organizations to several risks: leaks of confidential data, regulatory noncompliance (GDPR, AI Act), errors resulting from model hallucinations, loss of control over strategic information, and a proliferation of unmanaged tools.
How can we mitigate the risks associated with Shadow AI?
Effective management of Shadow AI involves several key steps: defining an AI usage policy, mapping use cases, training employees, securing sensitive data, selecting tools that meet security requirements, and establishing a governance framework that involves the IT department, business units, HR, and legal teams.
What role does governance play in the deployment of AI?
AI governance helps regulate usage, ensure regulatory compliance, protect data, and ensure the consistent deployment of AI solutions across the organization. It promotes responsible, secure, and value-creating adoption, while limiting “Shadow AI” practices.
Why Is the Traditional IT Department Model Reaching Its Limits (and How Can You Become a Digitally Optimized Company)?
More and more companies are asking themselves: Should we fundamentally rethink the way IT is organized to turn it into a true driver of value? That is precisely the goal of the
