Choosing between the Ubiquiti UDM-SE, UDM-Pro and UDM-Pro-Max? All three are 1U rackmount UniFi cloud gateways that run the full UniFi suite — routing, IDS/IPS security, VPN and a built-in UniFi Protect NVR. The key difference in one line: the UDM-SE is the only one with a built-in PoE switch, the UDM-Pro is the budget option without PoE, and the UDM-Pro-Max is the high-capacity flagship. Here's how they compare, with real Ubiquiti specs and Australian buy links.
Quick verdict
- UDM-SE — best all-rounder. Built-in 8-port PoE switch (180 W) powers your access points and cameras directly, plus a 128 GB SSD for faster UniFi Protect. Ideal for homes and small-to-medium business.
- UDM-Pro — best value if you already have a PoE switch. Same 3.5 Gbps security engine and camera capacity as the UDM-SE, but no PoE and no SSD.
- UDM-Pro-Max — best for scale. 5 Gbps IDS/IPS, 200+ devices, 2,000+ clients, dual HDD bays and 8 GB RAM for large UniFi Protect deployments (still no PoE).

UDM-SE — the built-in PoE all-rounder
The UniFi Dream Machine Special Edition is the only Dream Machine with an integrated 8-port PoE switch (180 W) — (2) PoE+ and (6) PoE ports — so it powers UniFi access points, cameras and switches directly, with no separate PoE switch required. It also adds a 128 GB SSD for a faster UniFi Protect experience and a 2.5 GbE WAN port for multi-gig internet. For most homes and small businesses building a complete UniFi network in one box, this is the one to buy.
UDM-Pro — same security, no PoE
The UDM-Pro shares the UDM-SE's 3.5 Gbps IDS/IPS engine, 100+ device capacity and 8 UniFi Protect 4K cameras, but has no PoE and no built-in SSD. It's the value pick if you already run a UniFi PoE switch and just need the gateway and NVR.
UDM-Pro-Max — the high-capacity flagship
The UDM-Pro-Max steps everything up: 5 Gbps IDS/IPS, 200+ managed devices, 2,000+ clients, two 3.5" HDD bays, 8 GB RAM and a faster 2.0 GHz processor. It's built for larger sites and bigger UniFi Protect camera counts — though, like the UDM-Pro, it has no built-in PoE.
Which UniFi Dream Machine should you buy?
Buy the UDM-SE if you want an all-in-one gateway that also powers your gear over PoE. Buy the UDM-Pro to save money when you already have PoE switching. Buy the UDM-Pro-Max for large deployments that need more throughput, clients and camera storage. Not sure? See our full UniFi routers & gateways guide or browse the UniFi gateways range.
Frequently asked questions
What is the difference between the UDM-SE and UDM-Pro?
The UDM-SE adds a built-in 8-port PoE switch (180 W), a 128 GB SSD and a 2.5 GbE WAN port. The UDM-Pro has no PoE, so you need a separate PoE switch to power access points and cameras. Otherwise both share the same 3.5 Gbps IDS/IPS engine and 100+ device capacity.
Is the UDM-Pro-Max worth it over the UDM-SE?
If you need more throughput (5 Gbps IDS/IPS), 200+ managed devices, 2,000+ clients, dual HDD bays and 8 GB RAM for a larger UniFi Protect deployment, the UDM-Pro-Max is the upgrade. If you want built-in PoE to power your gear directly, only the UDM-SE has it.
Do any of these have built-in WiFi?
No. The UDM-SE, UDM-Pro and UDM-Pro-Max are rackmount gateways — they don't broadcast WiFi. Add UniFi access points for wireless; all three power and manage them (the UDM-SE can power APs directly over PoE).
Which UniFi Dream Machine is best for a small business?
For most small businesses the UDM-SE is the sweet spot: one 1U box for routing, security, an 8-port PoE switch and a UniFi Protect NVR. Step up to the UDM-Pro-Max for larger sites, and choose the UDM-Pro only if you already have PoE switching.
