When should you use out-of-band communications?

How would your team stay connected if your primary communication network failed? To keep lines of communication open during emergencies, today’s leading organizations deploy out-of-band communication solutions alongside their main channels.

As a result, it enables team members to stay connected when main lines are compromised, corrupted, or otherwise unavailable.

How to train your team to use out-of-band communication systems

Out-of-band communication systems are critical to keeping IT, operations, and security teams securely connected during emergencies and mission-critical scenarios. By equipping team members with a communication channel that exists outside the organization’s primary network, decision-makers and leaders can rest assured that their teams can collaborate effectively when main communication channels are inaccessible or have been infiltrated.
