What is a secure SSL connection?

A secure SSL connection ensures the encryption of all data transferred between your computer and our server. It is used by bank websites and similar web services that require a high level of data security.

Is your website secure from intrusions?

Yes. The server is protected by many levels of security. First, there is a very restrictive firewall. Behind it, there are two systems that detect possible intrusions and continuously check the server’s integrity. There are NO OTHER services running on our server, and everything else is carried out on external servers (e.g. sending the e-mail when you register), as each additional service is a potential additional point of attack. We will contact prosecuting authorities on every detected intrusion attempt.

How do you prevent the possibility of data loss, e.g. in a hardware malfunction?

A back-up copy of all data is made every day to a server at a completely different location. The security of backed-up data is guaranteed, as the data is encrypted with a key accessible only from the main server. To further protect against any data loss, we keep back-ups for the past 10 days.
