The most secure. And fully private.

Three-levels of robust encryption and full data privacy protection in the most innovative business communication app.

Self hosted messenger and desktop

Throughout the years we have developed comprehensive security mechanisms to grant total privacy over your communication. Fully handing over your privacy to you.

Secure from start to finish

Zangi for Business uses 3 levels of robust encryption (including end-to-end encryption), securing the entire transmission of your content and metadata, from start to finish, and during transport.

Self hosted instant messaging technologies

No data collection

Zangi servers have no user communications. We have refused to collect or have access to your data, thus eliminating the possibility of monitoring, intruder entry, or backdoors leading to your personal data.

3 Levels of Encryption

Our multilevel military grade encryption scheme ensures the complete confidentiality and authenticity of calls and messages, even across the most vulnerable or hostile networks.

1. Encrypted proprietary handshaking mechanism

Used for encrypting authorization and session key exchange (encryption algorithms: RSA-2048).

2. Dynamic channel encryption

Used for encrypting each session between the client apps and the server ensuring the security of data transport (encryption algorithms: ​RSA-2048, RC4+)

3. End-to-End encryption.

Encryption keys exist only on user devices and nowhere else (encryption algorithms: AES-256, Curve25519, ECDH, HMAC-​SHA256​​).

All encryption and decryption happens directly on your devices. This guarantees that no third party — not even the server operators— can decrypt the content of private messages and calls.

Data privacy

Zangi’s competitive advantage is that it does not store any user’s communication history on its servers, thus eliminating the possibility of monitoring, intruder entry, or backdoors leading to your personal data.
