The foundation

Sovereign and secure by default.

Every feature of the AMVLET app is built on a foundation that puts control back in your hands — not in Silicon Valley.

Your infrastructure, your rules

Self-host on your own servers, in your chosen data centre, in your jurisdiction. Or let AMVLET host it for you on sovereign infrastructure — either way, you stay in control.

Encrypted rooms & channels

Organise team discussions with customisable, end-to-end encrypted rooms. From one-to-one direct messages to large project channels — all locked, all auditable.

Encrypted voice & video

1:1 calls, group video meetings, and large team calls — fully encrypted, hosted on your infrastructure. No Zoom servers. No Microsoft relay. No PRISM.

Full feature set

Fully-fledged features for serious conversations.

Everything your team needs — without the surveillance, the vendor lock-in, or the cross-border data exposure.

Built different

Under the hood

Security
End-to-end encryption built on the Matrix protocol — the same open standard trusted by major governments and defence agencies worldwide. Auditable, verifiable, and not dependent on any single vendor.
Usability
Familiar to anyone who's used WhatsApp or Slack — but without the surveillance. Onboarding takes minutes. Switching from US tools is seamless. Your team won't even notice the difference, except that their data is safe.
Speed
AMVLET's infrastructure is optimised for performance and reliability. Message delivery, file transfers, and video calls respond instantly — even across large encrypted rooms with thousands of participants.
Sovereignty
Your server, your jurisdiction, your keys. We never hold master decryption keys. The US CLOUD Act, the Patriot Act, and foreign intelligence legislation cannot reach data that was never on foreign infrastructure.
Open source
The entire protocol stack is open source and independently auditable. No hidden backdoors. No black-box encryption. Your security team can verify every claim we make — and so can independent researchers.
Compliance
Designed to meet GDPR, nFADP, NIS2, ISO 27001, and sector-specific regulatory requirements. Every message and file is stored, handled, and deleted in accordance with your organisation's data retention policies.
Why switch

Your tools are working against you.

The platforms your employees use every day are governed by US legislation, monetised through data profiling, and beyond the reach of your compliance team. Here's what the comparison looks like.

Common questions

Frequently asked questions

How is AMVLET different from WhatsApp or Microsoft Teams? +
WhatsApp, Teams, Zoom, and Google Meet are all owned and operated by US corporations subject to the US CLOUD Act and other foreign surveillance legislation. Your messages, files, and metadata can legally be accessed by US authorities without your knowledge or consent. AMVLET runs on sovereign infrastructure, uses open-source end-to-end encryption, and never holds keys to your data. We are structurally incapable of complying with foreign government data requests — because we don't have access to your data in the first place.
Can my SME afford this? Is it comparable in price to Teams or Zoom? +
Yes. AMVLET .PRO starts from €9 per user per month — comparable to Microsoft 365 Business Basic or Zoom Pro. For SMEs, the total cost of a data breach, regulatory fine, or compliance failure far exceeds the subscription cost. AMVLET .PLUS is free for individuals and small teams. Volume pricing and annual billing discounts are available — contact our sales team for a custom quote.
Do my employees need technical knowledge to use the app? +
No. AMVLET is designed to feel immediately familiar to anyone who has used WhatsApp, Slack, or Teams. Onboarding typically takes less than 10 minutes per user. The interface is clean, intuitive, and available in multiple languages. For enterprise and .PRO customers, we provide dedicated onboarding support and can arrange staff training sessions delivered by our compliance team.
What does "self-hosted" mean, and do I need my own servers? +
Self-hosting means running the AMVLET server software on infrastructure you own or control — in your office, in a private data centre, or on a cloud provider in your chosen jurisdiction. You don't have to self-host: AMVLET GROUP also offers fully managed sovereign hosting on GDPR-compliant infrastructure. The key difference from Teams or Zoom is that even in our managed hosting model, we operate a zero-access architecture — your messages are encrypted before they leave your device.
Is AMVLET based on Matrix? What does interoperability look like? +
Yes. AMVLET is built on the Matrix open standard — the same protocol used by the German federal government, the French military, and dozens of other sovereign institutions. Matrix enables secure federation between different sovereign servers, meaning your employees can communicate with users on other AMVLET or Matrix deployments without either party losing control of their data. There is no central point of failure and no single vendor lock-in.
How does AMVLET handle compliance with GDPR and NIS2? +
AMVLET is purpose-built for regulatory compliance. Our architecture prevents the data transfers to third countries that routinely put organisations using US-based tools in violation of GDPR Articles 44–49. Message retention, deletion, and archival policies are fully configurable per organisation. We maintain detailed audit logs, support data subject access requests, and can provide GDPR Data Processing Agreements. Our compliance training programme — delivered by our COO Julius Schmitz — is available to help your staff understand their obligations.
What happens if an employee's device is lost or stolen? +
AMVLET .PRO administrators can remotely deauthorise a device within seconds, revoking access to all rooms, messages, and files. Because encryption keys are device-bound, a lost device does not compromise message history on other devices. Combined with multi-factor authentication and our Advanced IAM module, your organisation can enforce strict device management policies — comparable to enterprise Mobile Device Management (MDM) but built natively into the platform.

Stop giving US corporations a front-row seat
to your business conversations.

Switching to AMVLET takes less than a day. Your team will barely notice the change — except that your data is finally yours.
