What kind of encryption are you using? Can it be cracked?
Depending on the service you are using, we are using 4096 bit OpenVPN, 4096 bit SSH-2 (Secure Shell 2), and 4096 bit SSL/TLS respectively, network and a tunneling protocols that allow data to be exchanged over a secure channel between your PC and our server. They are based on public-key cryptography to authenticate the remote computer and provides improved security through Diffie-Hellman key exchange and strong integrity checking via MACs. We are using AES-256 encryption to protect the confidentiality of the data. The cipher was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen. The algorithm has been analyzed extensively and is now used worldwide. As of 2007, no attacks that attack the underlying cipher itself have ever been found.

What kind of anonymization are you using? How safe is it?
We are running in general on each of our servers a Squid proxy with NCSA authorization, a SOCKS 5 proxy with identification, as well as an OpenVPN or PPTP VPN server. In general, all those proxy and VPN servers are configured for maximum anonymity while still guaranteeing the most reasonable usability, i.e. we are using a configuration that, while protecting your identity, still permits you to access 99.98% of the pages and services on the Internet without producing errors or rendering problems.

For example, we operate our Squid proxies not on „standard anonymity mode" but on "high anonymity mode," commonly called „elite proxy mode”, but not on „paranoia mode” either (as the latter basically permits you to view only plain text pages; you would be unable to submit forms or use web authentication.). This means in a nutshell, we remove your IP address completely, including in the „X-Forwarded-For” header; we deny the „From,” „Server,” „Referrer” and some other headers and replace your „User Agent” with an operating system that most probably will differ from the one you will be most likely using; but we leave other headers intact, as their absence from a security point of view only suppresses rather irrelevant information, while it will make you unable to browse and access many pages.

As a result, no web site receives data that personally identify you, but the web site will, for example, still be informed which content encoding your browser expects.

What is the speed of your servers? Will the connection be slower?
We currently sustain a multitude of servers with a bandwidth of 10 mbps to 1,000 mbps each. Most of our servers within Europe and North America are high-speed servers with an unshared and dedicated bandwidth of 100 mbps to 1 gbps with plenty or unlimited traffic, well capable to carry broadband traffic. If you are located in these areas and thus do have a very short latency time between 10 and 40 ms to one or more of our servers, you will hardly notice a speed difference. Our offshore servers, on the other hand, are for the most part equipped with dedicated 10 mbps or shared 100 mbps lines and unlimited traffic.
