A firewall is a primary method for keeping a computer secure from intruders. A firewall allows or blocks traffic into and out of a private network or the user's computer. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network. Firewalls are also used to keep internal network segments secure, for example, the accounting network might be vulnerable to snoop- ing from within the enterprise.

Following are the different methods used to provide firewall protection, and several of them are often used in combination. Beam Technologies has the capability to implement the best suited Firewall requirements for any enterprise.
