Most small offices don't need an expensive firewall appliance. They need a wired router that stays up, gives them a backup internet line, keeps guest Wi-Fi away from business devices, and can be managed without a site visit. These picks are spec-based: I chose them from the manufacturers' published specs and from what I'd put in for a client of that size. Where I've installed one myself, the product page says so.

I have personally installed and support the ER605 at my church. It has been in service for several years and we have had no issues with it. I set up 3 VLANs with this router: one for guests, one for staff, and one for management. We run phones on the staff VLAN as we only have 10 phones and 6 staff. There is a web based interface that is easy to use and configure if you understand basic router setup. TP-Link has lots of online support pages to assist you.

What actually matters in a small business router

  • Multi-WAN failover. If the office loses internet, work stops. A router with two or more WAN ports can fail over to a second ISP or a cellular backup on its own. This is the single biggest step up from a consumer router.
  • VLANs. Guest Wi-Fi, VoIP phones, cameras, and staff PCs should be on separate networks. Every pick here supports VLANs. You also need a switch and access points that support them.
  • Central management. TP-Link Omada and Ubiquiti UniFi both let you manage the router, switches, and access points from one dashboard, including remotely. That saves a truck roll for a lot of small changes.
  • Port speed vs. your internet plan. Gigabit ports top out around 1 Gbps. If the office has (or will soon have) a faster fiber plan, get a router with a 2.5G WAN port.
  • VPN. For remote staff or a second location, check which VPN types the router supports. WireGuard and IPsec are the common choices now.
  • No built-in Wi-Fi. None of these routers have Wi-Fi. That's on purpose. In an office you put the router in the closet and mount access points where people work.

TP-Link Omada ER707-M2: best overall value

The ER707-M2 is the one I'd start most small offices on. TP-Link's spec sheet lists one 2.5G WAN port, one 2.5G WAN/LAN port, four gigabit WAN/LAN ports, and a gigabit SFP WAN/LAN port. That's enough for a primary fiber line, a backup cable line, and room to grow. There's also a USB port for an LTE dongle as a last-resort backup.

The numbers hold up for a small office. TP-Link rates it at about 2.3 Gbps for NAT and about 1.5 Gbps (TCP) with IPS turned on, so a 2 Gbps fiber plan isn't a problem. VPN options include WireGuard, IPsec, OpenVPN, and SSL VPN. Rated IPsec throughput is about 650 Mbps, and WireGuard is 343 Mbps. It's fanless, has a steel case, draws about 7 W, and comes with a rack-mount kit. It can also sit on a desk or mount on a wall.

One thing to plan for: the Omada app, cloud access, and central management all need an Omada controller. That can be the free software controller, TP-Link's cloud controller, or a hardware controller. The router doesn't have one built in.

Skip it if: the office is already on UniFi. Mixing ecosystems means two dashboards.

TP-Link Omada ER605: best budget pick

The ER605 is the cheapest way I know of to get real multi-WAN failover. TP-Link's v2 spec sheet lists one gigabit WAN port, two gigabit WAN/LAN ports, and two gigabit LAN ports, so you can run up to three internet lines. There's also a USB port for an LTE dongle as backup. TP-Link rates NAT at about 940 Mbps each way, so it keeps up with a gigabit plan. It's managed by the same Omada controller as the ER707-M2, and it mounts on a desk or a wall.

The weak spot is VPN speed. TP-Link rates it at about 250 Mbps for IPsec, 83 Mbps for WireGuard, and 16 Mbps for OpenVPN. That's fine for a few remote workers on IPsec or WireGuard. It isn't enough if the whole office works over the VPN, or if you need OpenVPN.

Skip it if: the office has internet faster than 1 Gbps (or expects it within a few years), or relies heavily on VPN. All of its ports are gigabit.

Ubiquiti UniFi Cloud Gateway Ultra: best for UniFi networks

The Cloud Gateway Ultra is a small desktop gateway with the UniFi Network controller built in, so there's no separate controller to set up. Ubiquiti's spec sheet lists a 2.5G WAN port, four gigabit LAN ports, up to four WAN connections, 1 Gbps of IDS/IPS throughput, and support for 30+ UniFi devices and 300+ users. It's powered over USB-C and draws about 6 W.

The security and failover features go further than its size suggests. They include zone-based firewall rules, content filtering, ad blocking, license-free SD-WAN between sites, and failover to Ubiquiti's UniFi LTE Backup. VPN options include WireGuard, OpenVPN, L2TP, and IPsec site-to-site. Ubiquiti also lists it as NDAA compliant, which matters for some government contractors. Every WAN line you add uses up one of the four gigabit ports, so plan on a switch.

Buying note: Ubiquiti sells this mainly through its own store, and the Amazon listings I found were third-party sellers and bundles. The button for this pick goes to Ubiquiti's store directly. I don't earn a commission on it.

Skip it if: you want a rack-mount unit or more than four LAN ports. Plan on a switch either way.

Firewalla Gold Plus: best for security controls

The Firewalla Gold Plus is for offices that care most about seeing and blocking what's on the network: per-device rules, ad and content blocking, alerts for unusual traffic, and a VPN server, all from a phone app. It has four 2.5G ports and a quad-core Intel CPU, and Firewalla rates it at 5 Gbps of software packet processing. Firewalla doesn't publish a separate number with IDS/IPS turned on. VPN is a strength: Firewalla rates WireGuard at 500 Mbps and OpenVPN at 120 Mbps, and it supports up to 10 site-to-site connections.

It can run as the main router or in bridge mode behind an existing router, which helps when the ISP's equipment can't be replaced. Firewalla says standard features have no monthly fee. Mounting plates come in the box, and a rack tray is sold separately. It isn't part of the Omada or UniFi ecosystems, so your switches and access points are managed separately. Also I should add that setting up this kind of firewall device has a higher learning curve so expect it to take some time to get it right.

Skip it if: you want one dashboard for the whole network. Omada or UniFi will be simpler to manage.

Which one should you get?

  • Most small offices: ER707-M2, paired with Omada access points.
  • Tight budget, internet at 1 Gbps or less: ER605.
  • Already on UniFi, or want the most polished dashboard: Cloud Gateway Ultra, from Ubiquiti's store.
  • Security visibility comes first: Firewalla Gold Plus.

Is the ISP's router good enough?

For a one- or two-person office, often yes. Once you need a backup internet line, a separate guest network, phones, or remote access you control, a router you own is worth it. Most small offices are using a cable modem and router and then putting another router in after the cable company's router. That works, and you do not have to call the cable company to put the modem in bridge mode. But it is better to put the ISP's equipment in bridge mode (or passthrough) where possible, so you don't end up with double NAT. Then most times they are using a USB dongle or a separate cellular-to-Ethernet device such as a Digi or Cradlepoint.
