Voice Cypher

Bring government-grade security to your voice and messaging communications

Keep your conversations confidential.

You know how important it is to protect your emails, data and other electronic documents. But what are you doing to keep your voice communications secure? Verizon Voice Cypher helps you counter rising threats like call and text interception without requiring hardware or IT expertise. One simple app encrypts voice and messaging across wireless networks and Wi-Fi. And it’s all backed by our reach, expertise and security, so you can communicate without worry, virtually anywhere.

What is Voice Cypher?

Voice Cypher is a simple, hardware-free solution that protects all your employees’ voice and messaging communications through a single encryption app. It’s like a fortified door for sensitive conversations—blocking unauthorized access from would-be attackers and technologies. You’ll have peace of mind knowing your employees’ communications are protected. They’ll get an easy, seamless user experience across their mobile devices, PCs and tablets.

How does Voice Cypher work?

Just install the Voice Cypher encryption app. Every call made or received through the app is encrypted end to end to meet National Institute of Standards Technology (NIST) security guidelines. It works virtually anywhere, on any wireless or Wi-Fi network. So you’re covered even when you’re roaming or connecting across carriers. And since management is handled through an easy-to-use centralized portal, no special IT training is required.
