Network Security with pfSense: Architect, deploy, and operate enterprise-grade firewalls

The explanation about various ways pfSense can help secure your network is bang on. I really appreciated the fact the language is simple and the steps to setup things are detailed enough. I was able to setup a new pfSense firewall on an old Pentium PC I had lying around in the basement.

The book was well written and easy to follow. It seems to cover all the things necessary to understand pfSense from a security perspective. Recommended.

"pfsense is a really awesome free firewall. I use it to secure my home network. just buy a cheap old computer with 2GB of ram - and you are good to go."
