Installation and operation of firewalls

Our company has a long history of developing, installing and operating network perimeter security systems and firewalls. Development our own application level firewall system, several years of operating experience and our continuous professional training program ensures that our employees can proficiently handle any security questions arising. If necessary we create a customised network perimeter defense plan for your company together with your employees, our employees install the defensive device in accordance with the plan onto the machine supplied by us, or even to the appropriate computer provided by you. It is not a problem if the system has to provide diverse services as our local separation solution ensures that the individual subsystems don't endanger each other's operation. If necessary we can solve the traffic control of even more than ten networks with a single system. We have elaborate technologies for the solution of extreme security or operational reliability demands as well.

Possible functions of firewalls

The solution developed and installed by us is capable of fulfilling the following tasks:

• Preventing non-authorized or irregular traffic
• Verifying regular traffic between networks, detecting and filtering out the signs of an attack
• For the optimal internet bandwidth usage, it has a web acceleration function
• For mail transfer, it is capable of virus- and spam filtering
• If necessary, it is capable of dividing the bandwidth among networks according to a rule (a group or a service - for example mail - can be specified, and that can be given extra or lower priority)
• In case of high demand operations it is able to use not only the capacity of a multi-processor system, but even the collective performance of several computers
• If there's demand for it, then the administrator of the system is capable of configuring the network settings for the computers of individual systems from one location (with the help of the so-called DHCP server which is supported on all commonly used client and server operating systems)
• It is capable of co-operating with a large number of clients (there is no restriction on the number of clients)
• The supplementary security system makes possible appropriately secure log-ins to the network or to a given system and authentication of the users, even in case of extreme security conditions.

Developing special solutions

If your company must connect network traffic to its network for which there aren't ready defense solutions, then we can develop a defense system that is capable of analysing the given communication and intervene if necessary, either with our own firewall system, or an independent solution. In a case like this it's a serious help if the network communication is based on a known standard, but is not a disqualifying factor even if the form of the communication is unknown. Our analysis team will try to identify the communication protocol from the network traffic and develop a defense method with the help of the information acquired this way.
