Data protection, AI, and the search for trustworthy alternatives

It's something we hear about every day: many companies, especially in field service and after-sales support, rely on messenger services such as WhatsApp (WhatsApp Business Platform): fast, easy, familiar. However, with the growing integration of artificial intelligence (AI) at Meta (the parent company of WhatsApp, Instagram, and Facebook) and ongoing data protection concerns—especially in Germany—the Messenger is increasingly coming under pressure. 

With the rise of AI, is end-to-end encryption still worth anything?

Meta has been collecting large amounts of personal data for years. Even though WhatsApp advertises end-to-end encryption (E2EE)*, there are important limitations: E2EE protects content from access by third parties. However:

• WhatsApp and WhatsApp Business API encrypt message text end-to-end, but not metadata. This is a point of criticism for companies that need to implement data protection-compliant communication.

• According to datiq GmbH (lawyers), E2EE is available, but:

  “However, this is misleading—the encryption protects the content of the messages, but not the extensive metadata [...]. This information allows WhatsApp to create detailed analyses [...].” *

• According to ecovis.de (data protection officials, May 2025): WhatsApp Business App:
  The app continues to synchronize contacts and metadata and often stores backups unencrypted in the cloud, which is uncertain in terms of GDPR compliance. The API via BSPs allows for more privacy-friendly use—provided that app access to the address book is disabled and backups are controlled.*

• Automated interfaces (API), bots, or integrations via third-party providers can bypass encryption or process data on servers outside Europe.

• In the future, WhatsApp will be able to use Meta's AI models to analyze even more closely how and when companies communicate – even if the content remains encrypted. Metadata such as who communicates with whom and when will continue to be collected. Device information, contacts, location data, etc. will be processed.

• Cloud backups (e.g., in Google Drive or iCloud) are often unencrypted—a security risk.
  
  
  

The key question:

Can a company in Germany that is subject to the BDSG and GDPR use WhatsApp (Business API) in customer service in a legally compliant manner?
The answer: Only to a very limited extent – and often not at all.

* End-to-end encryption (E2EE): End-to-end encryption (E2EE) means that messages or data are encrypted in such a way that only the communication partners involved (sender and recipient) can read them.

How do mechanical engineers use WhatsApp?

In practice, WhatsApp (Business API) is widely used in mechanical and plant engineering, for example for: communicating with field technicians, queries about spare parts shipments, customer inquiries in the event of machine malfunctions, and exchanging images and videos for fault documentation. However, many companies are now recognizing the risks: Legal departments warn against uncontrolled data use, IT security officers demand documented processes, and auditability and traceability are often not guaranteed.

➡️ Companies are increasingly turning to alternative communication solutions that have been developed specifically for the B2B service sector.

What companies can do now
Our recommendation:

• Check whether WhatsApp is really necessary—or if it is only being used because “everyone knows it.”

• Get data protection officers and IT security on board early on

• Consider specialized service communication tools, such as bitnamic CONNECT Service Chats, if you want to work professionally and in compliance with the law in the long term

• Train your employees in how to handle sensitive data – including in chat

• Introduce a documented messenger policy in your company
  
  

WhatsApp is convenient — but increasingly poses a risk in industrial customer service.
In times of growing AI use, data analysis by large platforms, and increasing compliance requirements, it makes sense to consider alternatives such as Bitnamic's GDPR-compliant solutions.

Those who take data protection seriously build trust—both internally and externally.
