The firewall as a protective shield for your network

Protection against cyber attacks is essential for a secure IT infrastructure. Firewalls are crucial in this area and act as an outer line of defence to shield networks from threats. Hardware firewalls are special network devices that are used to implement security functions and optimise network security. Compared to software firewalls, which are installed on client computers, they are less susceptible to manipulation and offer greater protection against attacks. Centralised management of a hardware firewall is also much more efficient than configuring firewalls on individual systems.

How a firewall works

The task of a firewall is to monitor and filter data traffic between a network and the Internet or other networks. The firewall analyses all incoming and outgoing data packets based on defined security rules and decides whether to allow or block the data traffic. All events are logged to enable suspicious activities to be traced. Firewalls are therefore an essential component of IT environments of all sizes and increase protection against potentially harmful activities in companies to effectively secure sensitive data. In addition to individual security requirements, the complexity of the network is a decisive factor when selecting a suitable firewall that offers the required level of security by regularly checking for updates and adapting security rules to current threats.
