Our firewall systems are of the highest level of sophistication and offer various live services such as “Sophos Sandstorm” for excellent protection against viruses and other malware. Our firewall cluster immediately detects Trojans that “externally encrypt” documents and thus render them unusable. If a virus attack or tampering attempt is imminent, it automatically disconnects the affected devices from the network. Each attack is followed by a thorough examination and “cleaning”. In the process, our firewall system keeps learning and updates itself independently.
