Chat Control: These alternatives are available for companies

The planned EU regulation on "preventing and combating child sexual abuse" - better known as Chat Control - is about to be put to a decisive vote. On October 14, 2025, the EU Council plans to decide on Denmark's proposal, which provides for far-reaching monitoring measures.

What is Chat Control?
Chat Control (officially: CSAR Regulation) is a proposed EU law that would oblige messaging services and email providers to scan all messages from their users for suspicious content. This concerns:
- WhatsApp, Signal, Telegram and other messengers
- E-mail communication
- Cloud storage and file sharing
- Even encrypted communication is to be screened
The technical problem: client-side scanning
The proposed technology is called Client-Side Scanning (CSS). Messages and files are scanned directly on your device before they are encrypted and sent. This means that
- End-to-end encryption is effectively undermined
- A backdoor to all private data is created
- The security of all EU citizens is compromised
As Patrick Breyer, former EU parliamentarian for the Pirate Party, warns: "With demonstrably false claims, the Danish Council Presidency is trying to push through the controversial Chat Control 2.0."
Why chat control is dangerous
1. Undermining the encryption
The Internet Architecture Board (IAB) clarifies: Chat Control would "impose unrestricted access to private content and thus undermine end-to-end encryption."
2. Mass surveillance
Every message, every image, every file would be scanned - without suspicion, without a court order. This is mass surveillance without cause.
3. Technical uncertainty
Over 470 scientists from 34 countries have taken a stand against chat control. The technology is prone to errors and opens the door to abuse.
4. False Positives
Automated scans produce false hits. Vacation photos of your own children could be incorrectly marked.
Germany's position
Federal Minister of the Interior Nancy Faeser declared on behalf of the German government:
"From Germany's perspective, measures to screen encrypted private communications and measures that break, weaken, circumvent or undermine end-to-end encryption must not be part of the proposed regulation."
Nevertheless, the danger has not been averted. The Danish Council Presidency is pressing ahead with the project.
What does this mean for companies?
Chat control would have disastrous consequences for companies:
- Company secrets could be compromised
- Confidential customer data would be at risk
- Compliance issues with GDPR and other data protection regulations
- Industrial espionage would open the floodgates
- Legal and medical confidentiality could no longer be guaranteed
