Bastion

Vlux Bastion — the shield for your network

Security add-on for any Vlux network. Blocks the port for everyone except the gateway — your sensitive data stays behind a closed gate. Simple enough for any private user, robust enough for any business. Made in Germany.

Five layers of defense

Each layer works on its own. Together they form a defense in depth that holds even if a single layer fails.

1

IP allowlist at the firewall level

Only allowed IPs reach the Bastion container at all. Everything else is blocked before the server.

2

mTLS client certificate

Every connecting device identifies itself with its own certificate. Without a valid certificate — no connection.

3

Container isolation

Docker with AppArmor and Seccomp profiles. The Bastion process can’t reach anything outside its sandbox.

4

Vlux protocol auth (trust token)

Inside the tunnel, another Vlux-specific token check. Two independent layers of auth instead of one.

5

Rate limiting & anomaly detection

Suspicious behavior — many failed logins, unusual load spikes — is throttled and reported automatically.

No single layer makes a system secure. But anyone facing five hurdles usually gives up before that — and that’s exactly what Bastion is built for.

Who benefits most from Bastion

Examples where Bastion is useful — a law firm, a tax advisor or a practice, too, can keep their data in-house. Private users and businesses just the same.

Law firm

A law firm, too, can keep files and documents in-house instead of in a foreign cloud.

Vlux Bastion · VluxPC · VluxApp Learn more

Law firms work with sensitive documents. With Vlux Bastion the data sits on the firm’s own server instead of running through foreign cloud providers. Remote access goes through a single, controlled entrance, everything end-to-end encrypted.

Whether that meets the specific professional requirements is for the firm itself to check and decide.

What you need:

  • Vlux Bastion on a Pi box or mini-PC inside the firm
  • VluxPC on the lawyers’ computers
  • Free VluxApp for the clients

In beta With Vlux Drive: files sit only on the central Bastion server, the PCs show skeletons. If a laptop is lost, no data remains on the disk.

Tax advisor firm

Receipts and documents stay between client and firm on your own devices — without a foreign cloud.

Receipts, payroll, annual statements are sensitive data. With Vlux Bastion, clients send receipts by photo straight into the firm, end-to-end encrypted. The data lands on the firm’s own server — no foreign cloud in between.

Advisory recordings and documentation are managed in the same system, versioned and on your own hardware.

What you need:

  • Vlux Bastion on a Pi box or mini-PC inside the firm
  • VluxPC on the tax advisors’ computers
  • Free VluxApp for the clients

Medical practice

Patient data and recordings stay inside the practice, on your own devices instead of a foreign cloud.

Vlux Bastion · VluxPC · VluxApp Learn more

Medical practices work with especially sensitive data. With Vlux Bastion, patient records, finding photos and recordings stay physically inside the practice network instead of in cloud services under foreign law. Remote access runs through a controlled entrance with several layers of protection.

Image and progress documentation are managed in the same system as the records. Whether that meets the specific requirements is for the practice itself to decide.

What you need:

  • Vlux Bastion on a Pi box or mini-PC inside the practice
  • VluxPC on the practice computers
  • Free VluxApp for mobile finding capture

Premium features for Bastion users

Four properties that lift Vlux Bastion above classic security solutions — useful for any user, especially valuable in a business or law-firm setup.

Live today

VluxPC as admin cockpit

A Windows application manages your entire private infrastructure — Pi, Bastion, Drive and soon Mail. UX on par with cloud consoles, technically fully on premise. Synology has browser admin, Microsoft has a cloud console — Vlux has a desktop cockpit with automatic certificate authentication.

In pilot

Plug-and-play setup

Plug the Pi into your PC via LAN cable — the browser opens the setup page automatically. Click through the wizard, then plug the Pi into the router, done. Like an iPhone out of the box, no IT service needed. Factory-reset button for arbitrarily repeatable onboarding (second site, new employee).

Live today

Your own relay server

Premium bundle customers run their own Vlux relay instead of using our public one. That puts the connection metadata (who-talks-to-whom) in your hands too — for private users the data-sovereignty maximum, for licensed professionals BSI audit-ready and compatible with duty of confidentiality. With Vlux, everything is yours: data, gateway, address book.

In preparation

Per-user anomaly detection

The admin configures per-user a download threshold with an alert — low in a family setup, role-staggered in a multi-person business. When someone suddenly downloads 10 GB per day (data theft, stolen identity, malware), the admin sees it immediately.

Four promises you can rely on

What Bastion delivers in every use — and what professional rules of conduct require.

Full data sovereignty

Your data sits on your own devices. You keep full control — no foreign server gets your content.

End-to-end encrypted

AES-256-GCM between sender and recipient. Nobody in the middle can read along.

Made in Germany

Built in Schleswig-Holstein. Relay servers in Germany.

Built for data protection

No cookies, no third-party tracking, no third-party services — on this site or in the product.

Thank you.

The beta phase is starting now — with a fixed group of testers.

Beta running

Thank you to our beta testers

You're entering the beta with us while VluxNet is still young, and you're giving us your trust. You report bugs, shape features and help decide where the journey goes. That is exactly what makes the difference. From the heart: thank you.

Applications currently closed

The beta is running with a fixed group — we're not accepting further applications at this time. General availability is coming; then VluxNet will be open to everyone.
