The WeTransfer case brought to light a previously underestimated threat: file transfer platforms could use your data to train artificial intelligence models. This revelation raises a crucial question: are your confidential files already being exploited without your knowledge?
WeTransfer considered using files hosted on its platform to train AI models. Under pressure from users and regulators, the company backed down. But the simple fact that this option was explored raises questions about the practices of other similar services.
Many tools may share the same economic or technical logic:
Without visibility into actual terms of use and data flows, it's impossible to know if your content is or will be used to feed third-party AI models.
The problem is amplified by Shadow IT: employees use tools not approved by IT to transfer, convert, or store files. These practices escape all governance and privacy policies. A simple marketing campaign, a confidential contract, or source code can end up on servers whose operating terms remain unclear.
Avanoo provides a structured response to this challenge:
Avanoo detects and maps all file transfer, storage, and collaboration tools used in your organization. You see in real time which platforms are being used, by whom, and how often.
The platform provides a granular view of file sharing usage. You identify risky services, affected teams, and the volume of data potentially exposed.
Avanoo integrates an "AI risk" dimension into its analysis: tools likely to use your data for model training are identified and flagged, so you can act before an incident occurs.
The WeTransfer case should serve as a wake-up call. Anticipate rather than react: it's by controlling Shadow IT and mapping actual usage that you protect your confidential files from uncontrolled exploitation — including for the benefit of third-party AI training. Avanoo gives you the visibility and levers needed to take back control.
The risk is even greater when employees use unauthorized AI tools that can both exploit your data and feed third-party models. Learn how to optimize your SaaS spending while strengthening your security.
