Delta Chat deployed on independent chatmail relay infrastructure in under 10 minutes per user. Encrypted, works on mobile, requires no corporate account or corporate network to operate. When the corporate identity provider is down or compromised, your incident response team still has a secure, verified channel. Used as the crisis fallback that is always independent from whatever is failing.
For organisations that want to own their primary communications entirely: a self-hosted Matrix homeserver with Element client. No vendor dependency, no Microsoft or Google account required for access, fully federated if needed. Your communication infrastructure becomes sovereign in the same way your authentication infrastructure should be.
A documented, tested out-of-band communication protocol — who contacts whom, on which channel, in which sequence, for which incident types. The runbook exists on paper and on every responder's personal device, independent of corporate infrastructure. Tested in the tabletop exercise so the first time it is used under pressure is not the first time it is used at all.
Encryption keys verified out-of-band before the incident, so responders know they are talking to each other and not to an attacker who has compromised the corporate directory. Trust established in advance is the only trust that holds under incident pressure.
The crisis communication channel must be independent from the infrastructure that might fail during the crisis. Module 14 builds it.
