Acutis Best firewall for home & small business
Your router has a basic firewall, but a dedicated firewall gives you real visibility, intrusion protection and the ability to wall off your IoT gear from everything else. Here's what actually matters — then picks in three tiers, from plug-and-play to full DIY.

What to look for
- Dedicated firewall vs the one in your router. A standalone firewall sees and logs far more than a consumer router does — deep rules, traffic insight and protection your router can't match. If security matters, separate the two.
- Throughput. Inspection costs CPU. Make sure the box can do your full internet speed with IDS/IPS turned on — many cheap units quote a headline number that collapses once filtering is enabled.
- IDS/IPS. Intrusion detection/prevention spots and blocks known-bad traffic. It's the single biggest reason to run a real firewall instead of leaning on the router.
- VPN. A built-in VPN server lets you reach your home or office network securely from anywhere — and a VPN client can route outbound traffic through a provider if you want it.
- Managed vs DIY. Managed boxes (Firewalla, UniFi) are plug-and-play with a clean app. DIY (pfSense or OPNsense on a mini-PC) is more powerful and free as software, but you own the setup and tuning.
- Segmenting IoT. Put cameras, smart plugs and TVs on their own VLAN so a compromised gadget can't reach your laptops or NAS. This is where a real firewall earns its keep.
Dedicated firewall / security gateway
A box that sits between your modem and your network to filter, inspect and segment traffic. Match the tier to how much control you want and how comfortable you are with setup.
A firewall is only as good as the network behind it: put IoT on its own VLAN, keep firmware current, and confirm the box can hit your full plan speed with inspection on. Need to segment across multiple switches and APs? See best network switch.
A firewall you can't see into is a black box.
Running a firewall — Palo Alto, pfSense, a UniFi gateway — alongside switches and APs? Acutis Networks onboards and watches them all together: it sees the firewall's health, interfaces and changes next to the rest of your gear so you catch a problem before users do.
