Enterprise network security is a critical race to stay ahead of data breaches, fueled by two converging dynamics. First, network attacks continue to increase in sophistication, with the most ambitious efforts directed at data-rich enterprise networks. At the same time, the move toward beneficial cloud computing requires locating critical infrasturcture outside the normal security perimeter without introducing new vulnerabilities. Network security appliances from Netgate® with pfSense® software helps network professionals address both dynamics, with superior technology delivered at game-changing prices.

Appliance Guidance

The following outlines the best practices for choosing the appliance best suitable for your environment.

Feature Considerations

Most features do not factor into hardware sizing, although a few will have a significant impact on hardware utilization:

VPN - Heavy use of any of the VPN services included in the pfSense software will increase CPU requirements. Encrypting and decrypting traffic is CPU intensive. The number of connections is much less of a concern than the throughput required. AES-NI acceleration of IPsec significantly reduces CPU requirements on platforms that support it.

Captive Portal - While the primary concern is typically throughput, environments with hundreds of simultaneous captive portal users (of which there are many) will require slightly more CPU power than recommended above.

Large State Tables - State table entries require about 1 KB of RAM each. The default state table size is calculated based on 10% of the available RAM in the firewall. For example, a firewall with 1 GB of RAM will default to 100,000 states which when full would use about 100 MB of RAM. For large environments requiring state tables with several hundred thousand connections, or millions of connections, ensure adequate RAM is available.

Packages - Some of the packages increase RAM requirements significantly. Snort and ntop are two that should not be installed on a system with less than 1GB RAM.
