Firewalls are one of the most well-known security devices, but  most people are not entirely certain what they do. A firewall is a hardware or software device that filters all the traffic that comes through it. If you have a firewall placed in the correct position in your network, it will prevent attackers from gaining access to your network. If the firewall is not configured correctly, however, it is possible that it will prevent access to the Internet or other remote resources from your server or workstations. Firewalls are frequently built in to other network devices, but the best ones are standalone units that have hardware-based filtering. Different firewalls are available for different security requirements as well. To make sure you get the correct firewall for your needs, Contact Us today.
