Protectli Vault Pro VP4650 6-Port Firewall Appliance - Silent

In this review of the Protectli Vault Pro VP4650 the bottom line is simple: this compact, fanless mini PC is built for network professionals and small businesses that need a reliable, quiet firewall appliance with strong throughput and tested compatibility. The reviewer found the combination of an Intel i5-10210U CPU with AES-NI, six Intel 2.5 GbE ports, and a sensible 16GB RAM / 240GB SATA SSD configuration makes it a practical, ready-to-deploy platform for pfSense, OPNsense and other open-source routing solutions.

Key Features

• Processor: The Intel i5-10210U quad core with Turbo up to 4.2 GHz delivers responsive packet processing for stateful firewall and VPN workloads.
• AES-NI hardware acceleration: Built-in Intel AES-NI improves encrypted VPN throughput and reduces CPU load during heavy VPN use.
• Six 2.5 GbE ports: Six Intel 2.5 Gigabit Ethernet NICs provide flexible multi-WAN, LAN, and DMZ segmentation without needing extra adapters.
• Fanless, silent design: The passive cooling keeps the unit silent and suitable for office or home lab racks where noise matters.
• Included components: Ships with 16GB DDR4 RAM and a 240GB SATA SSD so it is ready for a quick software install and testing.
• Software compatibility: No OS pre-installed, but hardware is tested with pfSense, OPNsense and other popular open-source firewall distributions for straightforward deployment.

Who It's For

This appliance is aimed at sysadmins, MSPs and technically minded small business owners who want a dedicated, compact firewall platform with multiple 2.5 GbE ports and hardware AES acceleration. It suits networks that need stable, silent hardware for VPNs, VLANs and high-throughput routing without investing in full rack servers.

It is less suitable for users who want a turnkey commercial firewall with preinstalled software or for those who require hot-swap storage or internal expansion beyond the provided memory and SATA SSD. Casual home users who prefer guided setup and bundled subscriptions may prefer a consumer router instead.

Pros & Cons

Pros

• Fanless, quiet operation that fits in noise-sensitive environments.
• Six Intel 2.5 GbE ports that enable flexible network topologies without extra NICs.
• Powerful Intel i5 CPU with AES-NI for strong VPN and encryption performance.
• Ships with 16GB RAM and a 240GB SSD so it is ready for immediate software installation.

Cons

• No operating system is preinstalled, so some users will need technical knowledge to deploy pfSense, OPNsense or other software.
• Storage is a SATA SSD in the supplied configuration rather than NVMe, which may limit raw storage throughput for some edge uses.
