What are Firewalls for Business Networks? A firewall is a piece of hardware or software which functions in a networked environment to protect some communications restricted by the security policy, limiting viruses and problems with your computer network.

Firewalls for Business Networks can be thought of as a locked door which prevents specific material breaching the restricted area, with the limitations set by those in charge of the network.

Firewalls for business networks have built-in filters that can disallow unauthorized or potentially dangerous material from entering the system. It also logs attempted intrusions; a variety of proxy server with additional features. Firewalls are usually placed between the users of a LAN and the Internet (some ISPs also use firewalls) which can be set to screen for incoming viruses and only allow access to certain resources on the Internet as a security measure. It can also accumulate previously visited sites to avoid excessive use of bandwidth.

The firewall is typically a combination of many related programs, located at a network gateway server, which protects the resources of a private network from users from other networks. (The term also implies the security policy that is used with the programs.)
