# Gartner® Buyer's Guide to Out-of-Band Communication Platforms for Cybersecurity Incidents

### Evaluate whether your out-of-band (OOB) platform can keep the response moving when primary communications and identity systems cannot be trusted

When a cyberattack disrupts or compromises email, messaging, identity, or other primary collaboration tools, teams need a secure way to communicate. But moving the conversation out of band is only the starting point. 

Gartner® Buyer's Guide to Out-of-Band Communication Platforms for Cybersecurity Incidents helps organizations compare three approaches to OOB communications - ad hoc tools, dedicated platforms, and Cybersecurity Incident Response Management (CIRM) platforms - and evaluate their trade-offs. The report also helps buyers consider which approach best supports the work that must continue when normal communications and response systems are disrupted.

In this Gartner report, we feel you'll learn:

- **How the three OOB approaches compare:** See how ad hoc tools, dedicated OOB platforms, and CIRM platforms differ in scope - and when each model may fit the response you need to sustain.
- **Whether the environment is truly independent:** Evaluate resilience, access controls, identity dependencies, account recovery, and integrations when primary communications or corporate identity systems are unavailable.
- **What happens after responders connect:** Look beyond secure messaging to workflow coordination, retention, auditability, data sovereignty, AI capabilities, external participation, and the incident record.
- **How costs and provider options differ:** Consider onboarding, integrations, external-party access, retention, support, and other costs, and review representative providers across the major OOB categories, including BreachRx among the CIRM providers.
