Out-of-Band Secure Communications

When your primary communications are compromised, maintain secure coordination with an isolated, independent communication channel.

What is Out-of-Band Communication?

Out of Band Communications for Cyber Incident Response

When Your Primary Networks Are Compromised

During a cyber attack, your organisation's primary communication channels—email, Slack, Teams, and even phone systems—may be compromised or completely unavailable. Threat actors often target communication infrastructure to prevent coordinated incident response and maintain persistence in your environment.

Cellcrypt provides a completely separate, hardened communication channel that operates independently of your corporate infrastructure, ensuring your incident response team can coordinate effectively even when all other systems are down.
