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 dependency, no foreign infrastructure, no exceptions.
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, credentials, a server, an encryption standard, everything behind it is exposed. Silentel is built differently: each layer is strong enough to stand alone, and there’s always another behind it.

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

True sovereignty, not marketing sovereignty
The platform runs fully on your own infrastructure. No cloud, no third-party servers, no foreign jurisdiction touching the data at any point.
No personal data to expose, because none is collected
Silentel doesn’t require personally identifiable data to operate. There’s no identity data set to expose, because none was ever collected in the first place.
Nothing left behind on the device, even offline
The Silentel client application doesn’t store your data permanently, and if it loses connection to the server, it automatically blocks access and wipes what remains, entirely on its own.
Two independent layers, not a single bet
The post-quantum cryptography standards are new, and no quantum computer large enough to actually attack them exists yet, so their real-world strength hasn’t been proven the way older standards have. Silentel layers post-quantum protection over a second, independently strong classical encryption standard with real-world scrutiny and real penetration testing behind it.
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
