About

CacheGuard-OS is a free, open-source Linux-based network security appliance OS that turns any standard x86 machine into a UTM gateway. It sits between your devices and your ISP router, becoming the checkpoint for all internet traffic — no IT team required. Open-source since its first release, CacheGuard-OS includes: stateful firewall, web antivirus (ClamAV), URL filtering, SSL inspection, WAF (ModSecurity), VPN server (StrongSwan), web cache (Squid), QoS (IPRoute2), and WAN load balancing. It installs on bare metal or any common hypervisor in under an hour. Configuration is handled through a web-based admin interface with no command-line expertise needed. Built for small businesses, schools, and sysadmins who need production-grade network security on commodity hardware.

About

FreeBSD offers advanced networking, performance, security and compatibility features today which are still missing in other operating systems, even some of the best commercial ones. FreeBSD makes an ideal Internet or Intranet server. It provides robust network services under the heaviest loads and uses memory efficiently to maintain good response times for thousands of simultaneous user processes. FreeBSD brings advanced network operating system features to appliance and embedded platforms, from higher-end Intel-based appliances to ARM, PowerPC, and MIPS hardware platforms. From mail and web appliances to routers, time servers, and wireless access points, vendors around the world rely on FreeBSD’s integrated build and cross-build environments and advanced features as the foundation for their embedded products. And the Berkeley open source license lets them decide how many of their local changes they want to contribute back.

Pros & Cons from Real Users

Pros

  • A rock solid operating system with a long pedigree going back to the earliest days of UNIX, FreeBSD has been my operating system of choice for over 20 years. Although initial installation has always been easy, package management and updating at one time used to be more time consuming than your average Linux system but you now have the choice of either installing pre-built binary packages using the 'pkg' utility in the same way as for Linux or building them from source using the ports system, where you can customise a package's features and options before building & installing it. Another nice thing about FreeBSD is there are no sudden arbitrary upheavals with new releases - remember the big Ubuntu upheavals with first init, then Upstart and now systemd? Also, the descriptive device names for things like network interfaces have remained the same for decades (unlike Linux where they have changed several times in recent years and have now come back full circle to the 'eth0' style names in many cases! Support for virtual servers - 'jails' in FreeBSD parlance - has been a part of FreeBSD since 1999 and the open source version of the ZFS storage system developed by Sun Microsystems was enthusiastically adopted in 2008. I use FreeBSD for servers, nano-servers and also desktop systems and laptops. Finally, FreeBSD powers the world's largest streaming CDN (content delivery network) whose owners are a major contributor to FreeBSD development.

Cons

  • Setting up audio-visual hardware to work with desktop movie and music player applications can be time consuming, with a fully functional A/V set-up suddenly ceasing to work after a routine FreeBSD release upgrade and involved days of work to fix. Also online support is can be harder to find than for Linux but this is largely offset by the excellent online FreeBSD Handbook.
