Company VPN · WireGuard

Your own company network – everywhere.

Home office, field staff, office and servers in one isolated network. With WireGuard, the lean and fast VPN technology, set up in minutes via QR code.

01 What for

Securely connected, wherever you work.

Home office and field staff

Your team's laptops and phones sit in the same private network – whether in the office, at home or in a hotel. A new device is connected in minutes via QR code.

Fixed IP for allow-lists

In full tunnel every device appears with the fixed German IP address of our VPN server – handy for allow-lists. But all customers of this server share it, so it is not suitable as the only safeguard.

Safe on foreign Wi-Fi

In a café, at the airport, in a hotel: in full tunnel all traffic runs encrypted to our server in Germany. Anyone listening on the same Wi-Fi sees only encrypted data.

Connect servers and devices

A cloud server can be a device in your network too. That way you reach services that should not be openly on the internet.

Isolated

Every company gets its own network. Other customers' devices cannot see yours, and your network cannot be reached from the internet.

Manage devices yourself

Create a new device, scan the configuration, done. If someone leaves or a phone gets lost, remove the device with one click.

02 An example

From the office to the building site.

A made-up but typical example: a trades business with a server in the office, five fitters with tablets and a boss who travels a lot.

  1. Starting pointJob management runs on a server in the office. Nobody can reach it from outside, and putting the server openly on the internet is out of the question.
  2. Network and serverAfter ordering, the business adds the office server as the first device. It can now be reached in the company network, but still not from the internet.
  3. The fitters’ tabletsOne device per tablet in split tunnel: scan the QR code, done. Only traffic to the company network goes through the VPN.
  4. At a hotelFor trips, the boss adds his laptop in full tunnel. On foreign Wi-Fi all traffic then runs encrypted to our server.
  5. A tablet gets lostThe device is deleted in the customer center. Within about a minute it can no longer get into the network, everyone else keeps working.

06 How it works

On the network in three steps.

Order a plan

Once paid, your network is set up automatically.

Create a device

In the customer center under Company VPN, enter a name and choose whether only the company network or all traffic goes through the VPN.

Scan and connect

Install the free WireGuard app and scan the QR code – on a computer, load the file. We do not store the private key.

08 Frequently asked

Good to know.

What is WireGuard?
A modern VPN technology that is part of the Linux kernel and available as a free app for all common systems. It is faster and easier to set up than older technologies like OpenVPN or IPsec.
Which devices can I connect?
Anything there is a WireGuard app for: Windows, macOS, Linux, iPhone, iPad and Android – and servers running WireGuard.
Is this an anonymous VPN like the well-known providers offer?
No. The company VPN connects your company's devices into one network and optionally gives them a fixed address. It is not meant for disguising your identity, and sending email via port 25 is blocked.
What happens if a laptop gets lost?
You remove the device in the customer center. Within about a minute its key is no longer valid, all other devices stay connected.
Can I connect my office network?
Individual computers and servers in the office connect like any other device. Connecting a whole office network via a router is not part of the plan – get in touch and we will check with you whether and how it can be done.
Split or full tunnel – what is the difference?
In split tunnel only the traffic to your company network goes through the VPN; everything else goes straight to the internet as usual. In full tunnel all traffic runs encrypted via our server in Germany. You choose per device when creating it.
Do we get our own IP address?
In full tunnel your devices appear with the fixed address of our VPN server. This address is not exclusive: all customers of this server share it. On its own it is therefore not enough for an allow-list that should only let your company in.
Which DNS servers are used?
In full tunnel the configuration sets the public DNS servers of Quad9. In split tunnel your device keeps its own settings.
Can I download a device’s key again later?
No. The private key is created when the device is added, shown once as a QR code and file, and not stored afterwards. If it is lost, create the device again and delete the old one.
