Shadow IT has changed. It’s no longer just a matter of unauthorized software installed outside the IT department’s perimeter. In 2026, the nature of the risk has changed: it’s called Shadow AI, and it’s no longer just stealing control, it’s absorbing your know-how.
Every day, dozens of employees enter confidential data into ChatGPT, Gemini or Copilot with no defined usage policy, no traceability and no governance. The result: a silent and irreversible leakage of intellectual property to third-party infrastructures, often outside Europe.
Faced with this reality, there’s only one effective response: not banning, but governing.
Shadow AI: when risk changes dimension
Yesterday’s Shadow IT moved data to unauthorized storage. Today’s Shadow AI offers it for third-party training.
This is a fundamental difference. A file stored on a personal Dropbox remains recoverable. A prompt containing a sales strategy, a contract under negotiation or sensitive HR data, sent to an unmanaged public model, potentially becomes a permanent contribution to the knowledge base of a competitor or foreign player.
Productivity takes precedence over safety. 59% of employees use AI tools not approved by their company, and this figure rises to 93% among senior executives and managers (Cybernews, 2025). Prohibition doesn’t work: it pushes usage into the shadows.
The cost of a violation is documented. According to IBM, 20% of organizations have already suffered a Shadow AI-related data breach, adding an average of $200,000 to the cost of an incident. Prevention is no longer optional.
The exposure perimeter is invisible. AI agents don’t just pass through browsers. Chrome extensions, stealth APIs integrated into business tools, meeting bots that transcribe and analyze in real time: the attack surface is diffuse and underestimated.
IA Act 2026: from constraint to strategic opportunity
Gradually coming into force since 2024, the European IA Act is now in its full implementation phase. For many companies, it represents a source of concern, with fines of up to 7% of global sales, documentation obligations and compliance registers.
Organizations that approach it as a governance framework derive a sustainable competitive advantage.
Classification by use, not by technology. An automatic summary tool may seem harmless. It becomes a high-risk system as soon as it processes recruitment, credit rating, school evaluation or health data. The IT department needs to map not what the tool does, but in what business context it is used.
A dynamic transparency register. Compliance requires a living inventory: which models are used, by which teams, on which data, for which purposes. This register is not a static document, but an ongoing process.
Traceability of AI-assisted decisions. For high-risk systems, the company needs to be able to justify why a decision was taken, and what part AI played in it.
These obligations are actually an opportunity: organizations that address them seriously build a sustainable competitive advantage, complete visibility over their AI flows, risk control, and the ability to deploy new AI solutions with confidence.
Elit-Cyber's Detect-Govern-Secure method
To support CIOs in this transition, Elit-Technologies has structured a three-pillar operational approach, which can be deployed progressively according to the organization’s maturity.
DETECT – See what is invisible
The first step is visibility. You can’t govern what you can’t see.
We deploy Deep Packet Inspection (DPI) analysis tools capable of identifying AI agent signatures on your network in real time: browser extensions, API calls to external models, meeting transcription and analysis tools, bots integrated into collaboration platforms.
The result: an exhaustive mapping of your actual, not estimated, Shadow AI exposure.
GOVERN – Framing without blocking
Once the mapping is complete, we work with you to build an AI governance framework tailored to your business context.
This framework defines a secure Bring Your Own AI policy: which tools are authorized, on what types of data, with what levels of control. Each business use is set against the requirements of the AI Act to identify areas of risk and any necessary adjustments.
The aim is not to prevent the use of AI, but to make it traceable, compliant and aligned with your interests.
SECURE – Substitute by the sovereign
The final step is substitution. We replace identified Shadow AI usages with sovereign Private LLM instances, hosted on a controlled infrastructure, guaranteeing that your data never leaves your perimeter.
Your employees have access to high-performance AI tools. Your data remains your exclusive property. Your IA Act compliance is documented and auditable.
Frequently asked questions
Why is Shadow AI more dangerous than Shadow IT?
Shadow IT moves data to unauthorized storage, where it remains recoverable. Shadow AI offers it to a third-party model in a potentially irreversible way. It’s a leak of intellectual capital, not just a question of storage.
Where do I start to comply with the IA Act?
By auditing visibility. What you can’t see, you can’t make compliant. Mapping AI flows via DPI is the prerequisite for any serious governance approach.
Does the IA Act apply to SMEs and ETIs?
Yes. If your AI systems process data in high-risk contexts – HR, credit, healthcare, critical infrastructures – the obligations apply regardless of company size. Fines are proportional to turnover, not size.
How long does a Shadow AI audit take?
Elit-Technologies delivers an initial exposure report within 48 hours. The complete mapping and remediation plan is available within two weeks.
What is CIO and is it intrusive for employees?
Deep Packet Inspection analyzes network flows at protocol level to identify the signatures of AI agents. It does not analyze the content of personal exchanges, only the nature of connections to external AI services.
75% of employees already use AI at work, how do I know what’s allowed in my company?
This is precisely the starting point of the Elit-Technologies Flash Diagnostic. In just 48 hours, we identify the tools in circulation, the data exposed, and the gaps in IA Act compliance.
We don’t sell blocking. We sell sovereignty.
As certified experts in infrastructure and cybersecurity, ANSSI ExpertCyber, ISO 27001, we support CIOs of SMEs and SMBs in taking back control of their digital assets in the age of AI.
- Shadow AI visibility diagnostics: full exposure report within 48 hours
- IA Act compliance: exhaustive inventory, transparency register, remediation plan
- Deployment of a sovereign AI infrastructure: your teams have access to high-performance tools, and your data never leaves your perimeter.
59% of your employees probably use AI tools that are not referenced by the IT department. What data has already left your perimeter? Are you able to respond to an IA Act audit?
