Why Us?

Make secure calls with your existing iOS and Android devices. There are no special headsets or SIM cards. You don't need a single-purpose phone. With Silent Phone, no new hardware is required.
Enterprise-ready
Silent Phone is easy to deploy and manage in an enterprise environment. It requires no end-user training. It supports SSO, SIEM systems, and can be deployed via MDM. You and your team will have a dedicated client liaison and direct access to our highly trained technical support staff.
Premium security
We protect brand name enterprises, international NGOs, government agencies, and firms in such industries as defense, energy, and law. With Silent Phone, you're getting a premium product with top-notch security.
Unlimited user to user calling and messaging
Keep the conversation going from anywhere in the world. Silent Phone delivers unlimited worldwide calling and messaging between your users with no hidden or additional fees from us.
Data minimization
Stored data is a security risk. Many providers keep as much data as possible "just in case." We keep as little data as possible. We don't track IP addresses or keep logs of calls and messages between users.
