OPNsense® DEC740 – fanless desktop appliance with 10 Gbps firewall throughput
Three 2.5 Gigabit ports and two SFP+ at 10 Gbps, 10 Gbps firewall throughput, 1.2 Gbps IPsec and 4 GB DDR4 – in a fanless desktop enclosure of 190 × 160 × 28 mm.
The DEC740 is built around an AMD Ryzen Embedded with four cores and eight threads. Deciso lists it for firewall, routing, VPN, IDPS and web proxy. OPNsense® comes preinstalled with one year of the Business Edition included. The appliance is designed, manufactured and shipped by Deciso in the Netherlands.
Six reasons for the DEC740
10 Gbps firewall throughput
830 kpps, 8.5 Gbps port to port at 719 kpps, 150 µs average latency.
Five ports, two of them SFP+
3 × RJ45 2.5 GbE and 2 × SFP+ at 10 Gbps – fibre without an add-on card.
1.2 Gbps IPsec
107 kpps with AES256GCM16. Threat protection approx. 1 Gbps at around 85 kpps.
128 GB solid state flash
Plus 4 GB DDR4. 3,000,000 concurrent sessions per the manufacturer.
Fanless at 15 W
No fan, no moving parts. 51.2 BTU/hr heat dissipation, maximum 0.8 A.
Made in EU, two-year warranty
Carry-in & return directly from the manufacturer, including one year of OPNsense Business Edition.
Typical deployment scenarios
- Firewall and routing on connections up to 2.5 gigabit
- Fibre uplink over SFP+ without an additional network card
- IDS/IPS with Suricata and web proxy
- Site-to-site connectivity over IPsec
- Redundant operation with state synchronisation, two units required
Deployment scenarios are recommendations by inett based on the performance figures, not statements by the manufacturer.

Frequently asked questions
Which connection can the DEC740 serve?
Deciso states 10 Gbps firewall throughput at 830 kpps and 8.5 Gbps port to port. Over IPsec with AES256GCM16 it is 1.2 Gbps at 107 kpps, with threat protection approx. 1 Gbps.
Which SFP+ modules work?
Deciso publishes a list of tested modules, including FS SFP-10GSR-85, FS SFP-10G-T for RJ45 and DACs from Cisco, Aruba, Netgear and Ubiquiti. Standard LC-LC OM3 modules are likely to work as well.
Can 2.5 and 10 gigabit modules be mixed?
No. Deciso explicitly states that 2.5/5 Gbps and 10 Gbps link speeds must not be mixed – the hardware does not support it due to different frequencies.
How many VLANs and rules are practical?
Deciso states 4,093 virtual interfaces (802.1q) and recommends a maximum of 10,000 firewall policies for the user interface.
Want us to check the sizing?
We match connection speed, user count, VPN load and planned services against the performance figures. A short message is enough.
