Why a supplement to Microsoft Teams makes sense

Microsoft Teams is widely used in everyday office life. But as soon as your employees are on the road, working in production, or an emergency occurs, you reach your limits. This is precisely where Teamwire complements your communication, ensuring that operations continue even when other tools fail. Your organization remains capable of acting even in exceptional situations, and your mobile communication remains compliant with legal requirements.

Mobile employee communication

Easily reach mobile employees even without a desk or laptop. Service technicians, field staff, production workers, and nursing staff are rarely at their PCs. Teamwire works on any smartphone. Immediate, intuitive, secure.

Collaboration with Teamwire is fast, simple, and efficient. Thanks to topic-specific chats, broadcasts with hundreds of participants, push-to-talk, and distribution lists.

Frequently asked questions (FAQs)

Why is the US CLOUD Act a problem for companies and public authorities?

The US CLOUD Act allows US authorities to access data from US providers – regardless of where this data is stored. This means that even if your organisation opts for EU servers, Microsoft can still be forced to hand over data. This poses a massive risk for public authorities, critical infrastructure operators, healthcare providers and any organisation handling sensitive data. Teamwire is not affected by this, as the company is based entirely in Germany and is not subject to any US jurisdiction.

Can Microsoft Teams be used for emergency or out-of-band communication?

No. Microsoft Teams is not designed to function in the event of IT failures, VPN problems or cyberattacks. As soon as the Microsoft infrastructure is affected, Teams usually fails. Teamwire, on the other hand, runs on separate infrastructure, remains accessible even during IT failures, and offers alerting, push-to-talk, live location and broadcasting. Teamwire thus meets the requirements of NIS-2, DORA and CER, which Microsoft Teams does not technically cover.

Why should Teams not be used for sensitive or confidential communication?

Because Teams does not fully encrypt metadata, partially analyses data, communication patterns remain visible, data flows are not transparent, and it is centrally controlled by a US corporation. For confidential communication (C-level, incident command, medical data, police communication, etc.), this is an unacceptable risk. Teamwire is built for precisely such scenarios: 100% encryption, zero trust, no metadata analysis, 100% data sovereignty.

How does Teamwire protect my data better than Microsoft Teams?

Teamwire protects data through:

Complete AES-256 encryption
Encrypted metadata
Zero-trust
German jurisdiction
No analysis or profiling
Audit-proof audit logs

Many of these protection mechanisms are not available or only available to a limited extent in MS Teams.
