I have been a loyal Protectli fan for nearly a decade. During that time, I owned three Vaults. Each failed in about 3-4 years.By the third time around I began to consider the cost, averaging about $400 for each cycle. I entered a support request late in 2023. Engineer, Skip, suggested that, since I was getting a blank screen without even a startup sequence, it was likely a failed component. He advised that his company does not take an active role in troubleshooting or repair after warranty.I began to ponder the failure rate of Protectli, which seemed excessive for a simple device with no moving parts. I have a NAS and a workstation that have been operating at 100% up time since 2014 with only basic maintenance.After some research, I purchased two HP-T730 Thin Clients and installed: 16 GB of memory; a 500 GB SSD; and a Broadcom 4-port NIC---all were new and are sold on Amazon. Total cost for EVERYTHING was $400, about the same as ONE VAULT.I mounted and configured pfsense on both devices, used one as my primary firewall and the other as a backup.Now I get excellent firewall protection, FAST throughput, great reliability and easy repair or replacement for half the cost.Anyone savvy enough to setup a vault can also setup their own firewall on a lightweight computer. Although the power supply might be rated higher, it only uses the wattage consumed by the device, which is usually low.
