VoicePro Secure
Your conversations, no one else's. End-to-end encrypted voice and messaging - in the VoicePro app, and for your organisation. Powered by the VPX Voice & Messaging Connect+ platform.
Private messaging and calls, built in
Your messages and calls in VoicePro Mobile are end-to-end encrypted, so only you and the person you are talking to can read or hear them. Not us, not anyone in between.
Deploy encrypted comms for your platform or team
The same end-to-end encrypted voice and messaging, to build into your own product or run for your organisation. Made for legal, healthcare and financial services, where confidentiality is a regulatory requirement, not a feature.
How it's secured
The same encryption underpins both - in the app and for your organisation.
Open, audited standards
Built on the open Matrix protocol. Messaging uses the Double Ratchet - the same cryptographic ratchet as Signal; voice uses DTLS-SRTP. No proprietary crypto to take on trust.
End-to-end encryption
Messages and calls are encrypted on your device and decrypted only by the recipient. The network in between only ever sees ciphertext.
Per-session keys
Keys are derived per conversation (3DH key agreement) and never reused, so a compromise of one session cannot unlock another. Forward secrecy by design.
Zero-knowledge
We route the conversation; we never hold the keys. Content is unreadable by VoicePro infrastructure - we process ciphertext only.
Zero retention
Content is never logged or stored. Only the metadata your agreement requires is kept.
Private by default
