What is a Computer Firewall?

Firewalls are software programs that offer network security. They prevent unauthorized access to and from private networks, and they filter incoming and outgoing traffic. Firewalls are put in place to reduce and/or eliminate unwanted communication, and they protect your IT infrastructure with an added layer of security to prevent malicious attacks on your servers.

If someone is trying to access your company’s computers, they’ll hit the computer firewall first. It will fend off the attack and warn you that someone is trying to gain access. Some firewalls will also alert you to suspicious outgoing traffic as well as the incoming traffic.
