Core Features

Advanced security features designed for the most demanding privacy requirements

End-to-End Encryption SecurLine uses the most robust encryption algorithms currently available for military-grade protection: AES256-GCM AEAD, and Post-Quantum (PQ) cryptographic ephemeral key exchange with ML-KEM/X25519

Secure and private calling and messaging

Post-Quantum Ciphers SecurLine uses a PQ fork of Signal's double ratchet protocol, ensuring PRIVUS never has access to any encryption keys which are always generated and stored on the device. For key exchange we use the X3DH protocol with a Hybrid Curve 25519 / Kyber -Crystals for IM and attachment encryption, and HKDF based on SHA512

Future-proof against quantum computing threats

NATO NSA Certified SecurLine was certified by a NATO member's National Security Authority to protect classified government communications

Meets the highest security standards

Swiss Privacy Guarantees Switzerland is the only western country that takes privacy seriously and has no equivalent to the Patriot Act and similar legislation in the EU

Defense in Depth

Multiple layers of security to protect your communications

DEFENSE IN DEPTH

PRIVUS SecurLine is protected by 256bit AES advanced end-to-end encryption. PRIVUS never has access to your decryption keys or communication data. PRIVUS uses a zero trust architecture with servers located in jurisdictions that uphold privacy. Even in the case of a breach PRIVUS servers cannot reveal user communication.

COLLECT NO PERSONAL DATA

PRIVUS SecurLine does not collect or store personal data. PRIVUS SecurLine only requests application permissions that are essential for operation.

AVAILABLE EVERYWHERE

PRIVUS SecurLine features Advanced Evasion Technology™ (AET) to ensure communication remain protected globally. Using encrypted tunneling PRIVUS AET provides access to POST-QUANTUM SECURE communication from anywhere, including the world's most hostile environments.

ADVANCED DEVICE PROTECTION

PRIVUS SecurLine delivers endpoint protection against sophisticated exploits as well as binary integrity so clients have cryptographic proof the app hasn't been tampered with. PRIVUS SecurLine encrypts all application files separately, including messages, attachments and call history, and stores the keys in the secure enclave of the device where they can't be extracted or forensically cloned.

FORWARD SECRECY

Because every voice/video call, message and file is protected by a new ephemeral key, PRIVUS SecurLine is resistant to current and future developments in computing. With a new key for every piece of communication, your privacy is protected now and in the future against high-power quantum computers retroactively decrypting communication.

METADATA MINIMIZATION

Our Metadata Minimization Policy ensures that PRIVUS SecurLine collects no personally attributable metadata. This means that we only collect the basic technical information needed to provide support to our clients. Our zero-trust architecture means that even a back-end breach will not compromise any personal data. All metadata is securely wiped within 7 days.

NEW

Enhanced with SpyCatcher

Take your security to the next level by pairing SecurLine with our new SpyCatcher IMSI catcher detection device.

When integrated with SecurLine, SpyCatcher sends real-time encrypted alerts directly to your SL number whenever an IMSI catcher (Stingray) is detected. This seamless integration ensures you're always aware of surveillance threats while maintaining post-quantum encrypted communications.
