Security

Virtis s.r.o. company is focused on security issues, current security problems and of course on possible ways how to prevent risks.

Users

Currenty common net and internet users have still very low level of understanding of risks they often unnecessarily face and they are even not trying to control the way their communications or documents  are published. They usually can't distinguish authentic information from the forged ones and risk either the financial losses or social consequences.

Many providers are trying to prevent such problems but it is necessary for users themselves to take better and better care about the protection of their privacy and data and consistently examine how the other side ensures the entered data can't be tapped or misused.

Virtis s.r.o. company provides consultations and training for users and design and creating of security solutions for personal use - whether it is a VPN, personal signing and encrypting certificates or certificates for securing web sites not to allow tapping keyboard input into forms and have all the comminucation through the internet to the user encrypted. This web page uses one type of these certificates.

Spam

Huge problem of today is continuosly growing amount of unsolicited messages in incoming mail. Apart from spam being obtrusive there is also the part of it's dangers. Spam is usually sent with the intent to secretly install some dangerous program or to deceive users to disclose confidential information. The user himself can even become an unintentional spammer because the inserted program is sending spam from his computer to more and more victims.

Virtis s.r.o. utilizes several methods for spam filtering for both incoming and outgoing messages. Success rate is about 90% - an excellent result when trying not to falsely identify valid although suspicious messages as spam. We even provide the off-site mail filter where clients with own internal mail servers profit from such a high rate of success.

Servers

There is more and more messages about server attacks using flood techniques (DoS, DDoS), we daily encounter vocabulary attacks to common services (SSH, FTP) and with attempts to scan active ports of servers in our care. We have been able to detect and block most of these common attacks using our firewalls, some because of using specialized tools and programs to identify and deflect them.

We of course attend security conferences and study common and also not so common attack methods to be able to at least react to them in adequate ways. This is because we want to provide our customers with the highest possible level of security of their services (although we must admit we also study this because this area is of great interest to us).
