NATO approved · Post-quantum cryptography in live production
Sovereign secure communications for government and defence.
Silentel is a NATO approved, fully on-premises communications platform built for the agencies and forces that cannot afford a single point of compromise. No cloud storage, no foreign jurisdictions over your communication content.
Certified since 2006 and the first solution for standard commercial mobile phones listed in the NATO NIAPC catalogue. Post-quantum cryptography in live production. Deployed across 50+ countries.

Unique Multi-Layered Security Design
No single layer to break.
Most platforms have one thing standing between an attacker and your data. If that one thing fails everything behind it is exposed. Silentel is built differently: each layer is strong enough to stand alone, and there’s always several layers to avoid a single point of failure.

Verified, not self-declared
Independently reviewed and officially certified by national security authorities, with source-code review and on-site compilation available to any government agency that wants to verify it themselves.

True sovereignty, not marketing sovereignty
The platform runs fully on your own infrastructure. No cloud, no third-party servers, and no foreign jurisdiction with access to communication content.
Designed to minimise personal data exposure
Silentel is designed to operate with a minimal amount of personal information while reducing unnecessary exposure of user-related data.
Designed to minimise data retained on the device
Silentel is designed to minimise communication content retained on user devices and provides protective mechanisms when connectivity to the server is lost.
Two independent layers for session keys
Session keys are protected by two independent, layered mechanisms - established elliptic-curve cryptography and post-quantum cryptography - so a future break of either one alone would not expose a key. Message content itself is encrypted with AES-256.
Alongside all this: a 20-year track record with zero breaches, 48-hour deployment on devices your team already carries, and centralised control that never compromises individual privacy.
Government and Defence
For organisations that cannot afford a leak
Sovereign, on-premises, certified and NATO approved - built for agencies where a single compromised call puts operations at risk.
