Why Consumer Messaging Apps Like WhatsApp Pose Risks in Healthcare

Compliance Issues
Using traditional messaging services for professional purposes is not GDPR-compliant. Non-compliance can be costly for healthcare organizations: penalties for improper processing of health data can be substantial. Nevertheless, internal communication at many facilities continues to rely on unauthorized consumer messaging apps.
Lack of Security
A cyberattack can bring your IT systems to a standstill – and disrupt the communication channels your teams rely on. Hospitals are prime targets for ransomware. If your IT infrastructure goes down, staff may lose access to their usual communication tools exactly when fast coordination is most critical.
Shadow IT
Your staff may already be using private messaging apps that haven’t been approved by IT. Doctors and nursing staff rely on services like WhatsApp in their daily work because communication via messaging apps is fast and straightforward. For an organization, this means a loss of control over sensitive health and personal data.

How Threema Work Addresses These Three Challenges

Compliance with GDPR, NIS2, and C5
Threema Work fully complies with both the European GDPR and the Swiss Data Protection Act (FADP). A Data Processing Agreement (DPA) is included as standard, and data is stored in ISO 27001–certified data centers in Switzerland or self-hosted with Threema OnPrem. Additionally, Threema helps organizations meet guidelines and standards such as NIS2 and C5.
Communication That Works Even in Emergencies
Threema Work operates independently of your clinic’s IT infrastructure and software. If a system goes down, you can continue communicating via Threema Work and use the broadcast feature to reach specific teams in seconds. Make Threema Work part of your business continuity plan.

Full Control Instead of Shadow IT
The central management cockpit gives administrators control over who can communicate within the organization.Threema Work not only allows you to separate professional and personal communication but also lets you define communication and content-sharing permissions. If an employee leaves the organization, access can be automatically revoked.
