Out-of-band communication

When everything suddenly comes to a standstill, but decisions still need to be made: out-of-band communication (OOB) means having an independent communication channel that continues to function even in the event of failures. This allows you to remain capable of acting, coordinated, and confident in crises.

More than downtime

An IT outage is more than just a technical problem. It is a communication blackout. No emails. No telephone. No tools. No access.

High risks

If you can't communicate now, you lose more than just time: trust and control. And in the worst case, entire business units.

Ability to act

Out-of-band communication (OOB) provides a separate channel that stays up, so in crisis you act with confidence, not silence.

When standard solutions fail, it shows who is prepared

Email, phone, and tools like Microsoft Teams work fine — until an emergency. Then their weaknesses become apparent: dependence on a central system, lack of emergency functions, and inadequate data sovereignty. Teamwire, instead, was explicitly built for out-of-band communication.

	Email / Phone / MS Teams	Teamwire
Functional in the event of IT failure	Mostly affected	Works independently and immediately
Dependence on internal infrastructure	Strongly connected to main systems	Completely separate and self-sufficient
Mobile availability on any device	Partially	App, desktop, browser
Alerting & emergency functions	Not provided or only to a limited extent	Alarm, push-to-talk, broadcasts, distribution lists
Data protection / GDPR	Dependent on cloud provider and server location – usually hosted in the USA	100% GDPR-compliant, hosted in Germany, ISO-27001- and BSI-C5-certified
Logging & traceability	Only manually via admin log or post-processing	Audit-proof logs
User management & security	Limited control, often no MDM connection	Central admin role, MDM/LDAP/2FA integrated
Immediately ready for use	Partially high set-up effort in case of system failure	No setup necessary – immediately ready for use

Choose a real alternative now and be prepared for emergencies.
