TL;DR: When email, collaboration platforms, and messaging apps are compromised or unavailable, organizations lose the trusted communication channel they need for incident response and continuity, according to SSH Communications Security. The governance issue is not just transport replacement but whether the backup channel has independent trust, authentication, and infrastructure assumptions.
Editorial analysis by NHI Mgmt Group, based on content published by SSH Communications Security: “If Teams goes down, your teams need out-of-band communications”.
Key questions
Q: How should organisations set up out-of-band communications for incident response?
A: Organisations should predefine a separate channel for incident coordination that remains usable when email, chat, or collaboration platforms are compromised or unavailable.
Q: What breaks when primary collaboration tools are unavailable during a cyber incident?
A: Teams lose more than convenience.
Q: When should security teams prioritise secure communications over standard collaboration platforms?
A: They should prioritise secure communications whenever the conversation itself is sensitive enough that compromise, interception, or outage would materially affect operations.
Practitioner guidance
- Define an out-of-band communication trigger Specify the incident or outage conditions that require teams to move off primary collaboration tools and onto a trusted fallback channel.
- Separate trust domains for primary and fallback channels Select a backup communications path with different infrastructure, independent authentication, and a distinct administrative boundary.
- Govern sensitive communications as a control surface Classify which discussions must never move to consumer messaging apps, then map those conversations to approved secure channels.
Bottom line: Out-of-band communications address a resilience gap that appears when the normal collaboration stack cannot be trusted during an incident or outage.

Out-of-band communications are becoming a resilience control, not a convenience feature. The article’s central point is that communication failure can become operational failure when the primary collaboration stack is compromised or unavailable. That makes secure fallback channels part of resilience architecture rather than a nice-to-have add-on. Practitioners should treat trusted communications as a continuity dependency, not a separate productivity decision.
A question worth separating out:
Q: What is the difference between out-of-band communications and normal collaboration tools?
A: Normal collaboration tools optimise everyday work inside a shared operational environment. Out-of-band communications are designed to remain usable when that environment is untrusted, unavailable, or unsuitable for sensitive coordination, so the fallback path must stand on its own identity and infrastructure assumptions.
