Protectli Vault FW4B - 4 Port, Firewall Micro Appliance/Mini PC - Intel Quad Core, AES-NI, 8GB RAM, 120GB mSATA SSD

This is a nice little firewall box, I have Ubuntu Server 18.04 running on mine, acting as a firewall/router for my home network. For this purpose it works great.

Been running PF sense a year+ with no issues. The device looks very professional and has adequate specs for a good PF Sense firewall.

Fantastic appliance, great price and performance.

I didn’t have any problems running this box with opnsense. Everything worked out fine configuring as a firewall.

Started out with 1 vault, planned to have 2 vaults for managing 2 locations. The first one came with bad RAM and bad CPU.

Zero issues loading and running OPNSense. No loss of throughput with Suricata and various services enabled and CPU stays under 30%. I am happy with my choice.

I have been running for a month or so with Sophos Home UTM 9.7 at home. Works great no issues or complaints.

I use this as my firewall/router at the colo facility Im hosted at and it is a solid unit, does not require any maintenance or cuddling and very compact design.

Been running this little guy for over two years without issue. It runs warm but rarely consumes more than 15% cpu. pFSense has been updated three or more times and its been trouble-free. I host a public facing website and this device protects my network for all sorts of intrusions.

I run pfSense on this unit, which is a truly superior routing solution. If you have been running DD-WRT-style firmware on proprietary hardware (i.e., prosumer wireless routers), this is a major step up in terms of reliability and horsepower. It can easily process 500mbps traffic through the firewall--which is my current ISP maximum--and terminate VPN traffic at about 100mbs. It will presumably run OPNsense--or your favorite full Linux distribution--without a hitch.
