Scheduling a secure call for 3pm.
Everything your team needs. Nothing they don't.
Secure messaging, voice calls, and file sharing — built from the ground up for organizations that value genuine privacy.
End-to-End Encrypted Messages
Conversations stay between your people. Always.
Encrypted Voice Calls
Crystal-clear calls, completely private.
Your Own Infrastructure
Dedicated servers. Your data never shares a home.
Multi-Device Support
Seamlessly move between your devices.
Panic Password
Instant emergency access revocation when it matters.
Post-Quantum Ready
Built for the threats of tomorrow, not just today.
Sealed Sender
Even message metadata stays private.
Native iOS Experience
Built specifically for Apple devices.
Security that speaks for itself.
Built on the Signal Protocol — the gold standard in encrypted communication. Enhanced with post-quantum cryptography to stay ahead of emerging threats.
Signal Protocol
Individual encryption for every message. Forward secrecy means compromising one key reveals nothing about past or future conversations.
Post-Quantum Ready
Built with ML-KEM-768 post-quantum cryptography to protect your conversations for decades ahead.
Zero Knowledge
Your encryption keys live exclusively on your devices. We have no mathematical ability to access your content — and that’s by design.
Your company. Your servers. Your rules.
Every Synapse deployment is a completely isolated environment. Your own application servers, your own database, your own encryption infrastructure. No shared tenancy. No cross-contamination risk.
