Internet attacks are very common nowadays. A firewall fends off malicious attacks and protects the internal IT infrastructure, therefore plays an indispensable role in a computer network. Break-in attempts are made not only by hackers, but also by semi automated software looking for security holes and reporting them back to the attacker. Such an attack may be followed by a more serious manual attempt to break in. The firewall monitors network traffic and decides whether or not to permit that traffic based on the customized rules. With a firewall you can control the internet activity at your company, even deny access to certain websites. We distribute both physical firewalls from renowned manufacturers and Microsoft and Linux based software firewalls.
