China and the USA mutually allege each other of bringing router technology on the market that is equipped with backdoors for the purpose of economic espionage. Due to the NSA scandal, it is unquestionable that, even with network providers, confidential data is no longer secure. Companies as well as commoners find their confidence shaken; the State is unable and in some cases unwilling to cope with this problem. Who can you trust now?

We are Viprinet, a router manufacturer developing and producing in Germany. The bug-proof end-to-end encryption of our VPN routers is entirely in your hand, and only you have the key. Our products are free of any backdoors, and we do not cooperate with any intelligence agencies nor are there any laws that would require us to give up on our security maxims. 

To connect your company sites securely with each other, our routers use several reasonably priced consumer media like VDSL, LTE/4G, 5G or satellite connections bonded together. The data is encrypted and divided up onto the different links. Owing to this risk distribution onto several access networks, your site-to-site connection also becomes highly reliable, at low running costs – and even in the most remote areas or in mobile usage scenarios.

In the following, we'll explain in detail why you can unconditionally trust us and our products:

Viprinet does not provide intelligence agencies in any jurisdiction with special access to Viprinet products. Should an intelligence agency or a secret court order attempt to force Viprinet to implement a back door in any Viprinet product, we pledge to inform all our customers in that country if legally possible, to immediately cease pursuit of new business in that country, and to withdraw from that country at the earliest opportunity.

It has to be assumed that hardware produced in the US but also in China is delivered with backdoors ex works. Only seldom, alleged European manufacturers are completely in control over the production chain for their products. Backdoors can thus be contained in products even without the manufacturer knowing about it. For IT security products produced in the US, it has to be assumed judging by the current state of facts that they contain backdoors for the NSA. For products of Chinese manufacturers, a backdoor for Chinese intelligence agencies has to be assumed. 

In Germany, there luckily are no kangaroo courts that could decree backdoors in products. Also, no such ambitions of German intelligence agencies have yet become public.

Our products are developed entirely in Germany. Software source codes are protected from external access in an almost paranoid way, and the hardware for our router products is also developed and produced entirely in Germany.

As a design principle our devices are split up internally in a "clean" and a "dirty" part. The "dirty" part is the one communicating with public networks, e.g. VDSL, Satellite, LTE/4G or 5G modems. These components partly come from third party manufacturers in Taiwan, China, Korea, and the US as these companies hold the patents on said modem architecture.

We do not trust these parts in our design; they are treated like the unencrypted Internet, and are only used to establish an encrypted connection via them. The "clean" part of our products is completely under our control. The "dirty" part is separated from the "clean" part on the hardware but also on the software level.

For encryption, all Viprinet VPN products use known industrial standards which are regarded as safe and unharmed by the NSA by security researchers.

These are in detail:

• TLS 1.2 and 1.1
• RSA 2048
• AES 256
• SHA-1 and 256

Due to Edward Snowden's disclosures, it has to be assumed that the NSA may be trying to compromise widely common encryption libraries like OpenSSL or hardware encryption chips. US manufacturers are suspected to provide the VPN protocol IPSec of their devices with backdoors.

It has to be stated clearly: Viprinet doesn't use any unverified encryption engines of third parties. Our routers sure are equipped with hardware encryption engines; however, these originate from different manufacturers of different regions in the world, and are never used exclusively – we only use them in combination with encryption systems we've implemented in our software ourselves. Thus, our products are invulnerable for any of NSA's attack scenarios known so far, especially for weak random number generators.

Another advantage of Viprinet bonding technology is the fact that in our bonded VPN, only a fraction of the encrypted data is transmitted over a single Internet medium. Attack scenarios in the networks of network providers which have been conducted according to news accounts fail when used against our technology.
