Whatsapp - Professional Life / Personal Life Confusion & Shadow IT

A very interesting analysis by Agathe SIDER from a legal standpoint.

But this decision also raises a question that CIOs encounter every day: Shadow IT.

When professional exchanges take place on WhatsApp, outside of company-approved tools, several risks arise:

🔐 Circulation of professional data outside the information system

📂 Lack of archiving and traceability of exchanges

🌍 No control over data location and sovereignty

And in practice, these groups are often created without consulting the IT department.

The result is a parallel information system that is impossible to govern.

This case law therefore serves as a reminder of one essential point:

Internal communication is part of the information system and must be managed as such.
