To ensure overall network security, a VPN is right and important. You get a secure tunnel that lets you surf and access your data remotely. VPNs are very useful not only in tech-savvy households, but especially in companies. Here, VPNs help protect the information employees send and receive online from third parties.
What VPN hardware is available?
Which VPN type it will be in the end depends on various factors. The first important question is: Should it be VPN hardware or VPN software? In a direct comparison, the VPN hardware that is particularly secure, flexible and scalable wins. We strongly believe that secured VPN hardware closes an important security gap. Many risks already arise from the incorrect configuration of VPN software – especially if no expertise is available. Our PrivacyCube is a very good example of VPN hardware combined with the OpenSource VPN software.
VPN hardware is a virtual private network based on a standalone device. Authentication, encryption and other VPN addons are managed in the device’s processor. VPN hardware is particularly secure . The device, which contains its own processor, manages authentication, encryption, and other VPN functions. VPN hardware offers a high level of security, but can be expensive to purchase.
Basically, VPN hardware on most devices involves time-consuming and complex maintenance. For example, if the company wants to expand, it is necessary to purchase additional VPN hardware. VPN hardware is especially suitable for large enterprises. Our own IT department takes care of maintenance and can regularly replenish stocks. Our Privacy Cube system is cost-effective and maintenance-free!
A VPN router is a pre-installed router that establishes a VPN tunnel. A secure connection between multiple end devices is possible with this. A standard router cannot establish a VPN connection. This would only work via VPN software or via our upstream PrivacyCube.
VPN boxes are relatively new on the market. With our PrivacyCube we are the first providers of a VPN Box in Germany. The VPN Box is portable, pre-installed VPN hardware. Users can connect the Cube directly to their router via the Plug & Secure function or directly to the laptop in the café. The VPN box secures all devices in the home network or just the laptop in the wifi of the café. VPN boxes are small and handy and are particularly well suited for mobile use (remote, travel or field office). Since the VPN software is pre-installed, it is easy and convenient to use – no prior knowledge is required.
Brief introduction of the PrivacyCube
The PrivacyCube is the first pocket-sized Plug & Secure hardware. It works with OpenVPN. The VPN software is pre-installed, so no configuration is necessary. The “Privacy” in the PrivacyCube stands for the highly secure connection. Unlike other VPN providers, there is a 24h key exchange as well as multiple key sizes (4,000-8,000 bits).
Our PrivacyCube thus closes the gap for small and medium-sized enterprises on the one hand. They often cannot yet afford expensive VPN hardware. On the other hand, our VPN Box reaches people without VPN knowledge – that is, families and private households as well.
The PrivacyCube is the all-round talent for companies and private households
No other VPN offers such highly secure encryption technology. It takes several earth ages to have all possible combinations tried out with a computer. So no code can be decrypted by hackers in this life. The PrivacyCubeis the high-end device in the field of IT security.
With the PrivacyCube, up to 50 users and 25 end devices are connected to our VPN service simultaneously. This is ideal for start-ups in particular, and even more so for small companies that have little expertise. The pre-installed VPN software works automatically. All end devices connect easily via the wifi. As soon as the VPN Box is connected to the router or to an end device, the VPN connection is secure and stable. Employees who work in the field or from home can connect the PrivacyCube to their laptop. Monthly subscriptions eliminate the need for costly VPN hardware. With conventional VPN providers, you pay monthly per end device. For us, it’s the cube alone that counts. It doesn’t matter how many end devices you connect via the Cube. This offers flexibility for private households and emerging companies. It is very easy to put the PrivacyCube into operation. You just have to connect the PrivacyCube to your DSL router. The PrivacyCube is equally suitable for IoT-based households and home networks with multiple end devices. Any digital nomad, small business owner or smarthome enthusiast can operate the PrivacyCube. It is the safest all-rounder designed for the majority of society. We want data security for everyone! The PrivacyCube can be used multifunctionally and it fits into any pocket size.
When does a software solution make sense for VPN?
For smaller companies, VPN software has paid off to date. This has changed with the introduction of the VPN Box. The VPN application runs on a server and secures the data traffic.
The advantage: VPN software is cheaper at the beginning. Licenses can be purchased easily. With a little know-how, the software can be set up and scaled flexibly. If you have a lot of expertise, you can make VPN software your own and customize it to your individual needs. VPN software is suitable for people with a lot of previous knowledge.
The PrivacyCube, on the other hand, is a true all-rounder, as it allows for many things: flexibility, cost-effective and highly secure VPN technology, and convenient deployment.

What software solution is available?
Basically, a distinction is made between commercial and open source VPN software. There are two main VPN types:
- client-based VPNs
- network-based VPSs
Both VPN types establish a secure and encrypted VPN tunnel. Client-based VPNs secure traffic for individual devices. Network-based VPNs secure the entire network – multiple end devices included!
A client-based VPN is private network established between a single user and a remote network. An application establishes the VPN connection. Most popular VPN providers offer client-based VPNs. As a subscriber to a VPN client, you enter your username and password. The client establishes an encrypted tunnel to the remote network. The tunnel is encrypted and all data can pass securely through the VPN tunnel.
Also Windows, Mac and mobile operating system provides a standardized VPN. Mac OS X 10.10 uses L2TP (Layer 2 Tunneling Protocol) over IPsec and PPTP (Point-to-Point Tunneling Protocol).
Opera offers a VPN browser, which we have already reported about. Many corporate networks and universities use client-based VPNs. The employees or students can connect to the control center via with their Ipad or laptop when they are at home or on the road.
However, what many free VPNs do not offer is a firewall that covers possible leaks. Premium VPN clients license firewalls, dramatically increasing security.
Network-based VPNs connect two networks via a trusted network. This variant is very often used in corporations. IPsec-based WAN enables all locations and stations in an enterprise to be connected with IPsec tunnels. The three most popular network-based VPNs are:
- IPsec tunnels (routed and policy-based)
- Dynamic multipoint VPNs
- MPLS-based L3VPNs
The standards-based IPsec tunnel is suitable for most network-based routers and firewalls. Unlike OpenVPN, however, IPsec is always tied to hardware.
Open source solution OpenVPN
OpenVPN offers numerous advantages as it is an open source solution or client based model. OpenVPN works with OpenSSL and is built on standards. It is comparatively easy to set up and flexible to use. Of course, the open source solution contributes to its popularity.
OpenVPN from DN8 improved
OpenVPN offers 256-bit encryption and high-end ciphers. Man-in-the-middle attacks are thus prevented. Another plus: there are no compatibility issues with firewalls. Each port can be used on TCP or UDP. Thus, OpenVPN offers a lot of flexibility to secure multiple devices at the same time. Perfect Forward Secrecy enables random key exchange every time data is exchanged.
We have used the OpenSource technology for our Cube and highly developed it. Our VPN technology with automatic key exchange is unique.
The OpenVPN software is already pre-installed on our PrivacyCube. Nevertheless, convince yourself of the OpenVPN technology that we use as VPN client software for our VPN hardware. We have provided the download for you here:

Depending on the security requirements, the size of the company or the number of end devices, VPN software, VPN hardware or a combination of both is necessary. Our PrivacyCube can meet the security needs of both business and home users in a simple and scalable way. With the Plug & Secure function, it belongs to the new generation of VPN boxes and is therefore suitable for mobile use. IT security is a very fast growing market and there is currently a lack of scalable products. With our PrivacyCube, we have succeeded in closing the gap.
