What Secure Voice does

Secure Voice is a secure communication platform developed and operated by 5Pro Software GbR, a German civil law partnership founded in 2009 and headquartered in Frankfurt (Oder). The company provides government-level encrypted voice calls, instant messaging, group chats, push-to-talk, file transfer, and IP deskphone encryption for government agencies, international corporations, and state-owned enterprises. The platform runs on standard iOS and Android mobile devices and connects to customer-deployed on-premises servers, which the company positions as the core differentiator against cloud-based competitors whose servers can be compelled to share data with authorities.

The underlying technology is a proprietary binary communication protocol layered with AES 256 encryption, ECC 571/DH 16384 key exchange above NIST TOP SECRET requirements, ephemeral keys per call, and a 9+ layer security architecture that supports HSM authentication, device watermarks, and customer-modifiable algorithms. The platform supports 3G, 4G, WiFi, 2G, satellite (including Thuraya), and isolated Intranet/MPLS/VPN environments, and ships with a management panel for administrative control. An IP deskphone add-on extends the same encryption to landline endpoints.

Secure Voice generates revenue through one-time platform/server licensing, white-label OEM agreements with system integrators who rebrand the solution with full localization, professional services for custom deployments with hierarchical key management, and a subscription component tied to upcoming modules including encrypted conference calls, video calls, telepresence support, and NFC authentication. Pricing is not publicly disclosed and contracts are multi-year. The company is founder-managed by two Managing Directors, has no disclosed external funding, and claims trials in 50+ countries.
