What is a firewall?

 

A firewall is a hardware device or software used to help keep a network secure. Its primary objective is to moderate all inbound and outbound network traffic by analyzing the packets and determining if they are to be granted access or not, based on a defined set of rules. 

 

A firewall traditionally is placed in-between a LAN (Local Area Network) and a WAN (Wide Area Network, usually the internet). This placement creates a single point of contact for the entire outside network to pass through before being granted access to your local network.

 

Firewalls block unwanted network traffic, both inbound and outbound, for every device connected to the LAN.

 

Types of firewalls

 

  • Dedicated proprietary hardware designed specifically to function as a firewall can offer decent performance, but can run into licensing limitations and cost escalation.
  • OS based firewalls can be deployed on a much larger hardware base, and offer the same, if not better performance for a more reasonable price.

 

Our solution

Here at HGL, we take a hands on approach and design firewalls to fit every budget. From a small, monitor mounted PC, to a full 3U rackmounted server, all sizes and configurations are available and can scale to any network demand, whilst still being affordable.

 

We use pfSense (complete feature list here) as our firewall distribution on our machines. pfSense is a customized version of FreeBSD (UNIX) designed specifically for use as a firewall/router. This robust, security oriented distribution is based on a UNIX program, pf (packet filter). pfSense allows users to customize every aspect of the firewall with a user friendly web-based GUI.

 

With our firewall designed specifically to meet your needs as a company you will be able to:

  • Restrict outbound access to specific websites
  • Block outbound access to specific ports (ftp, telnet, etc.)
  • Have full control over any and all inbound connections
  • Block ads on a network wide basis
  • Prevent inbound attackers from gaining access to network resources
  • Create remote VPN access for users working from home or on business trips
  • Seamlessly link two or more offices together via VPN, so computers, printers, file serversmail servers, etc. are accessible from any of the connected offices
