Government and Defence
Communications security for the organisations that cannot afford a leak.
Silentel is built for and used by the agencies and forces where a single compromised call or message can put people, operations, or national security at risk. Sovereign, on-premises, and NATO approved.
Who this is for
Where the coordination channel itself is part of the target
Built for intelligence services, ministries of interior, defence forces, law enforcement, and presidential and prime ministerial offices, and any organisation where the coordination channel itself is part of the target.
The risk landscape
The gap in your perimeter
You’ve hardened the network. You’ve hardened the facilities. You’ve hardened the devices. But the conversations that coordinate all of it, voice calls, messages, shared documents, frequently still run over commercial platforms hosted on infrastructure you don’t control, in jurisdictions you don’t choose, with metadata logged by parties who answer to someone else.
This isn’t a hypothetical gap. It’s the one category of exposure that rarely shows up in an audit, because a professional adversary has no reason to reveal what they already know.

Metadata exposure
Who spoke to whom, when, and from where. Even encrypted content can leave a metadata trail that maps an entire operation.

Cloud and jurisdictional dependency
Infrastructure hosted outside your control, subject to another country’s laws, access requests, or simple outages.
Supply chain and interception risk
Commercial platforms built for a mass consumer market, not for an adversary with nation-state resources and patience.
Unverified implementation
The standard used matters less than whether it was implemented correctly. Without independent review, flawed implementations and unpatched vulnerabilities can sit undetected indefinitely.
The Silentel answer
No single layer to break
Every layer of Silentel’s design is strong enough to stand alone, and there’s always another behind it, so a single point of compromise never becomes a single point of failure. Sovereignty, verification, data minimisation, device behaviour, and encryption each add independent protection.

Fully on-premises
Deployed entirely on your own infrastructure and live within hours - not months. No cloud, no foreign servers, no third party with access to your traffic.

No personal data to expose
Silentel doesn’t require personally identifiable data to operate, and logs no metadata by default, so there’s nothing retained for an attacker, or anyone else, to find.
Two independent encryption layers
Post-quantum cryptography is new, and no quantum computer large enough to actually attack it exists yet, so its real-world strength hasn’t been proven the way older standards have. Silentel layers it on top of a second, independently strong classical standard with real-world scrutiny and real penetration testing behind it, so protection never rests on just one.
Forensic-resistant by design
The client application doesn’t store data permanently, and wipes autonomously if it loses connection to the server.
Verified, not self-declared
The first solution for standard commercial mobile phones listed in the NATO NIAPC catalogue, independently reviewed by national security authorities, not just self-certified. A 20 year track record, zero breaches, across 50+ country deployments.

Questions worth asking any vendor
Where is your data actually stored, who can access your metadata, what happens to a device that’s lost or seized, what’s your track record, and can you prove your security claims.
A track record that speaks for itself
20+ years in secure communications, zero breaches, deployed across defence and government organisations in 50+ countries.
