Filax: Exchange classified files

Offline. Manageable. Built for the highest confidentiality levels.

No network? No problem. Filax helps you move sensitive files safely between separated environments, with clear audit logs, without relying on network connectivity.

What is Filax?

Filax is an offline file encryptor for domain‑separated environments. It enables secure transfer of confidential files:

  • Without a network (air-gapped, offline, domain-separated)
  • Using sovereign NL/EU cryptography (no foreign black boxes)
  • Fully auditable transfers (traceable, provable compliance)
  • Easy to operate (designed for real-world use under pressure)
  • Compact, low-profile, field-ready (pocketsize)
Filax is designed to function under pressure, especially when circumstances are far from ideal.

Is Filax relevant for you?

Security policy says: isolate networks. Operations say: information still has to move.

In defense, government, and critical environments, connections are temporary, separated, or intentionally absent, while classified data keeps flowing between teams, locations, and missions. Filax enables secure, sovereign file exchange when networks are not an option (air-gapped, offline, domain-separated).

It's for you if:

  • Your environments are air-gapped, offline, or domain-separated
  • You handle data up to NATO (Cosmic) Top Secret
  • Digital sovereignty is a requirement
  • Designed for continuity: operations keep running, even when line encryptors go down.
  • Developed in close cooperation with the Dutch MOD and international partners

Typical environments:

  • Integrated capabilities across all defense domains
  • Government & diplomatic posts / embassies
  • Defence and Critical Infrastructure suppliers & high-assurance integrators

Benefits of Filax

This is what you get with Filax:

Operational continuity

even when critical systems are unavailable

Stronger compliance posture

through auditable transfers

Lower total cost of ownership (TCO)

via usability + manageability

Sovereign control

aligned to national requirements

How it works

1.

Connect Filax to a laptop in the classified environment

2.

Open the local interface (web UI) and select the file(s) you want to send or transport

3.

Choose approved recipients (users or groups) for each file

4.

Filax encrypts the file(s) and writes the encrypted output to removable media (e.g., a USB drive)

5.

Transport the removable media or send the encrypted file via an approved method (policy-dependent). This can be an untrusted channel (internet or a courier)

6.

On the receiving side: connect the Filax of the receiver, load the encrypted file, and decrypt for the intended recipient

Quick Filax check

If you answer “yes” to 2 or more, a discovery call is likely worth it

  • Do you exchange sensitive files between separated domains?
  • Are you currently relying on manual transfer or fragile processes?
  • Do you need NL/EU sovereignty or strong assurance expectations?
  • Do audits require traceability of who sent what to whom?
  • Do you need a backup plan when approved links or services are unavailable?
  • Do you need to exchange classified files with external organizations or partners without connecting networks?

Use cases

Embassies

Secure exchange on red networks with irregular connectivity

Integrated capabilities across all defense domains

Ships, submarines, aerial and land operations

High assurance supply chains

For suppliers to communicate securely with partners (up to Top Secret)

Technical specs Filax

A Filax solution deployment consists of up-to thousands of PFL’s. Each user has their own PAT, that can be used to access all the PFL’s that the user has access to. Each solution deployment is supported by a single CTP, the management station.
