Network Security Systems
Today more than ever, your critical data must be stored and accessible from multiple physical locations. The challenge is to securely connect your private business applications between cloud-based data centers, onsite servers, and offsite backup. You need to stay connected across the internet while keeping your data secure. But, how do you protect your sensitive information while allowing your office, remote users, and clients to communicate freely?

By combining General Technics network security hardware platforms with some of the best open source packet filtering and routing software available, you can create complete firewall solutions that are more flexible and often more capable than off-the-shelf firewalls, and at a lower cost.
The Hardware:
General Technics is offering three different hardware platforms to best suit the size of your business and the arrangement of your network. They are all low in height, short in depth, and rack mountable for easy installation. Two gigabit ethernet ports are usually sufficient for most small businesses and home environments, allowing for one WAN interface for the upstream internet connection, and one LAN interface for the filtered side of your network. Additional network ports allow you to expand the router's capabilities with more complex multi-WAN or multi-LAN, with failover and load-balancing for a robust and secure network. GT provides the hardware as a platform, fully assembled, tested, and ready for you to install the firewall software of your preference.

The Software:
There are many options when it comes to open source firewall and routing software, but after testing and using these ourselves, we highly recommend these two. They are both free to install and use, are well maintained, and are among the most trusted firewall software in the industry. Despite their simple to use web interfaces they are packed with powerful firewall and routing features that give you more control over your network security than other firewall solutions. For support, full documentation, and a full list of features we invite you to visit their official websites.

A strong focus on security and code quality drives the development of the project, and it offers weekly security updates to react to new emerging threats, as well as two major releases each year. It includes high-end features such as forward caching proxy, traffic shaping, intrusion detection and easy OpenVPN client setup. The pfSense project is a free network firewall distribution, based on the FreeBSD operating system with a custom kernel, supporting including third party free software packages for additional features. It can provide the same functionality or more of common commercial firewalls, without any of the artificial limitations.
