SonicWall NSa 3700 02-SSC-4326 1U Rackmount Firewall, Appliance Only
Overview
The SonicWall Gen 7 NSa Series is a 1U next-generation firewall line for medium- to large-sized enterprises. The 02-SSC-4326 is the NSa 3700 appliance. It is supplied as Appliance Only: the firewall, VPN and routing run on SonicOS 7, while SonicWall support and optional security subscriptions are sold separately.
Technical Details
The SonicWall NSa 3700 02-SSC-4326 is a 1U rackmount next-generation firewall running SonicOS 7, with 24×1GbE RJ45, 6×10/5/2.5/1GbE SFP+, 4×5/2.5/1GbE SFP+. Threat Prevention throughput is 3.5 Gbps with Gateway AV, Anti-Spyware, IPS and Application Control enabled (5.5 Gbps firewall inspection), and it holds up to 2,000,000 concurrent SPI connections. This part number is Appliance Only: SonicWall support and optional security subscriptions are sold separately. It is used at a campus or main-office internet edge, in the DMZ and between user and server segments.
Best For
The NSa 3700 suits a campus or main-office internet edge that needs 3.5 Gbps of Threat Prevention throughput and up to 2,000,000 concurrent SPI connections. It suits buyers who already hold SonicWall support or plan to add it. Size against the Threat Prevention figure, not the firewall inspection throughput.
Not suitable if:
- your inspected traffic exceeds 3.5 Gbps, the published Threat Prevention throughput
- you need security services included in the part number, since this one is Appliance Only

FAQ
Does the SonicWall NSa 3700 02-SSC-4326 include a security subscription?
No. The 02-SSC-4326 is Appliance Only: firewall, VPN and routing run on SonicOS 7, while SonicWall support and security subscriptions such as the Advanced Protection Security Suite are sold separately.
How much traffic can the SonicWall NSa 3700 02-SSC-4326 handle?
SonicWall publishes no user count, so size the NSa 3700 on its figures. Firewall inspection throughput is 5.5 Gbps, but Threat Prevention throughput is 3.5 Gbps with Gateway AV, Anti-Spyware, IPS and Application Control enabled; size against that. It holds 2,000,000 concurrent SPI connections and 750,000 DPI connections, and opens 22,000 new connections per second.
What interfaces does the SonicWall NSa 3700 02-SSC-4326 have?
The NSa 3700 provides 24×1GbE RJ45, 6×10/5/2.5/1GbE SFP+, 4×5/2.5/1GbE SFP+. Management and console connectivity is 1×1GbE RJ45 out-of-band management, 1×Console, 2×USB 3.0. Transceivers for any SFP-type ports are sold separately.
Does the SonicWall NSa 3700 02-SSC-4326 support high availability?
The NSa 3700 supports Active/Passive high availability; stateful synchronization requires SonicWall's optional Stateful HA Upgrade license for the NSa 3700 series.
What is the difference between the NSa 3700 and the NSa 4700?
Both run the same SonicOS 7. The NSa 3700 is rated at 5.5 Gbps firewall inspection throughput, 3.5 Gbps Threat Prevention throughput and 2,000,000 concurrent SPI connections; the NSa 4700 is rated at 18 Gbps, 9.5 Gbps and 4,000,000. Check both interface sets in the specification tables.
Does the 02-SSC-4326 include SonicWall support?
Support is not included with an Appliance Only part number. SonicWall support and optional security subscriptions are sold separately, and Network Devices Inc. confirms the correct support option before the order is placed.
How is the SonicWall NSa 3700 02-SSC-4326 managed?
The NSa 3700 is managed through Network Security Manager (NSM), and locally through the SonicOS web interface and CLI. Firewall policy, SD-WAN, VPN and high availability are configured on the appliance; the security services on it are licensed separately unless this part number bundles them. SonicWall includes centralized management and alerting as part of support, so NSM management needs an active support contract or security bundle.
Is the 02-SSC-4326 end of sale?
Yes. SonicWall's Last Time Buy notice for the NSa 3700 set its Last Order Day at October 31, 2025, with Active Retirement Mode from November 1, 2025, Limited Retirement Mode from November 1, 2027, the last one-year support order on November 1, 2029 and End of Support on November 1, 2030. SonicWall recommends the NSa 3800 and above as the replacement.
What condition is the 02-SSC-4326 sold in, and what warranty applies?
Network Devices Inc. supplies the 02-SSC-4326 new and factory sealed. It is covered by a one-year Network Devices Inc. warranty and a 30-day return window. Orders ship from our New Jersey and Texas warehouses.
