Protectli Vault 4 Port, Firewall Micro Appliance/Mini PC - Intel Quad Core (Atom E3845), AES-NI, Barebone

Review Update: 2/11/19: I now have over 1 year of run time on this device and it has preformed wonderfully. I do have to say it tends to run a little warm. I have a small usb powered fan that I didn't need anymore so I have it running on low blowing across the top of the unit. Even with the minimal air flow it makes a noticeable difference. In my environment the unit runs at approx 25% ram utilization and an average of .4 CPU. One thing to note, if you are using pFSense, it does not active the crypto support by default. To enable it you need to go to: System - Advanced - Misc - Cryptographic & Thermal Hardware. Enable the AES-NI CPU acceleration and while you are there you might as well enable the Intel Core CPU on die thermal Senor.This is a great platform to build a new pfsense router. It supports the new AES-NI so the hardware is compatible with future versions of pfsense beyond 2.4.X. Running 4gb ram and 120GB MSATA. Install was a breeze using the built-in svga port and USB keyboard. Install of the memory, ram, and pfsense install took about two hours. All of the network ports were recognized with no issues. Highly recommend for a SOHO device.

This unit is a great home router for those that need a small form factor PC to run PFsense or Opnsense.I have tested with both, and all hardware is functioning as expected. I opted to install a M.2 sata SSD on this model in order to handle the storage of the operating system.It has been running 24/7 for over a year in my home-lab environment and has had no issues so far. Simply installed my router's OS and configured. Have had to do no maintenance other than setup.The unit also supports AES-NI instruction sets, so for those that want to implement a router level VPN, you will be able to leverage hardware acceleration for OpenVPN.I'm getting full gigabit speeds on all 4 interfaces to my LAN and WAN and the unit still manages to stay cool.Some may opt to put a small fan nearby to cool the fins on the top, however i have had no issues leaving it on open air cooling as well.

This has worked great for me, and I'd highly recommend it as an embedded network appliance at the price point. I've tried it with both pfSense on FreeBSD and Ubuntu Server on Linux, and all hardware seems to work natively without any rough corners or weird drivers.Since I imagine most people are going to use this as a network appliance and not generally have a display connected to it, the serial COM port (and included RJ45 to DB12 cable) is a fantastic benefit that you rarely see in consumer network hardware. It gives full access to the device's BIOS setup interface and most OSs' boot consoles, and makes setup and network troubleshooting far easier than the traditional approach of repurposing a keyboard and monitor, or the embedded router hell of resetting and praying for a default network configuration. I was able to install and configure pfSense from scratch without connecting a display or keyboard. Ubuntu required video to do initial setup, but could be configured to support the serial console shortly thereafter.The chassis build quality is solid, all the ports are flush and well aligned, and access to the DIMM slot, two mSATA slots, and SIM slot (still unsupported in the US? See the Q&A section) are accessible under the bottom panel with four screws. There are pre-drilled and grommeted holes for installing antenna, though the options for equipping this device with wireless hardware are somewhat limited, so you may want to look elsewhere if homebrewing a WAP is part of your plan - the only officially supported wireless card is a USB based 802.11a/b/g only device.It comes with a bracket for hanging this off of a standard monitor VESA mount, but since it's so ill equipped to drive a modern display, I can't anticipate that this would be useful. I can see no reason why you couldn't use it as a wall mount bracket, though, as this device would probably be pretty well suited for hiding in a network closet somewhere.The link, activity, and HDD LEDs are all clustered on what I would vaguely consider to be the "back" of the device - the side with the DC in and network ports, where one is likely to have the most wires plugged in. This makes it mildly inconvenient and ugly to position the device where these LEDs are actually visible, but whether this is something you'd even want to do is mostly a matter of preference.

This is a great little box for SOHO firewall / endpoint protection. The hardware is standardized x86-64 Intel compatible, so it will run most modern OSes. I tried out Untangle on it and performance was good. I put 8GB of RAM into this system along with a 250GB Samsung 850 EVO mSATA SSD.The console access can be hit or miss, depending on the OS you ultimately use. pfSense has a serial console installer, but Untangle does not, so if you are like me and have a monitor that does not accept a native DB15 VGA connection, do yourself a favor and get one of these: Cable Matters VGA to HDMI Scaler Converter Cable with HD 1080 Video and USB Audio Support This will allow you to convert the analog VGA signal to a digital HDMI signal that you can use for an honest video output.The biggest drawback to this unit is the spacing, or lack thereof, between the VGA and USB connections. When you have a standard size VGA cable attached, the clearance for the adjacent USB connections is VERY minimal, and will definitely dictate what you plug into this unit. I had to get creative with which USB sticks and keyboards I used concurrently on this unit. I even had to pull out a USB 3.0 hub to be able to use some different combinations of peripherals. Once you have everything installed and deployed, then the USB/VGA port clearances don't really matter, but when you have it in the back office to work on, you will likely throw a few expletives out when connecting vital peripherals.If I had one suggestion for improvement for the manufacturer, it would be SPACE OUT THE USB and VGA PORTS MORE! See my photos for some of the troubles I had.All in all, great looking, well-performing hardware in a power-sipping package, but with some design flaws.

I purchased this a little over a year ago and love how fast/easy it is for pfsense NATting and VPN. A little while ago I noticed the CPU cores were getting hot (80-100C) and experienced some errors on the WAN interface as reported by pfsense. I emailed Protectli and asked if that was a normal temp - it was not (supposed to be 30-40C). They treated this with urgency and sent 2-day mail a replacement with a pre-paid RMA sticker. Replacement firewall works great/cool - very happy with this purchase and company (I *never* write reviews BTW).
