SonicWall NSA NSa Series Security Appliances - Refurbished, Used, New
The SonicWall NSA and NSa Series is the rack-mounted midrange line, sitting between the desktop TZ appliances and the enterprise NSsp platforms. It is the range most organizations land on once a single site outgrows a desktop firewall, or once a campus needs 10 gigabit uplinks and a connection table measured in millions.
The naming is worth decoding before you shop. SonicWall writes the Gen 6 models as NSA and the Gen 7 models as NSa, and there are three distinct families in play: the original Gen 6 x600 series, the Gen 6.5 x650 refresh, and the Gen 7 x700 series.
The three NSa families at a glance
| Family | Generation | Models | Firewall range | Max connections |
|---|---|---|---|---|
| NSA x600 | Gen 6 | 2600, 3600, 4600, 5600, 6600 | 1.9 to 12 Gbps | 225K to 750K |
| NSA x650 | Gen 6.5 | 2650, 3650, 4650, 5650, 6650 | 3.0 to 12 Gbps | 1M to 5M |
| NSa x700 | Gen 7 | 2700, 3700, 4700, 5700, 6700 | 5.2 to 36 Gbps | 500K to 6M |
Browse by generation: NSa Gen 7 or NSA Gen 6.
Gen 6, Gen 6.5 or Gen 7?
The x650 refresh was about connections and ports, not speed. An NSA 4600 and an NSa 4650 both do 6.0 Gbps of firewall throughput. What changed is the connection table, 400,000 on the 4600 against 3 million on the 4650, and the arrival of 2.5 gigabit and 10 gigabit SFP+ ports. If you are replacing an x600 with an x650 expecting it to be faster, it will not be. It will handle far more simultaneous sessions and give you better uplinks.
Gen 7 is where throughput actually jumps. The NSa 4700 does 18 Gbps against the 4650's 6.0, and threat prevention goes from 2.5 to 9.5 Gbps. New connections per second nearly triples. If the reason you are shopping is that inspection is throttling a fast circuit, Gen 7 is the answer and Gen 6.5 is not.
The case for Gen 6 is firmware consistency and budget. If your estate runs SonicOS 6.5 and you need to add or replace a chassis without splitting across two firmware generations and two management experiences, Gen 6 hardware is the sensible buy, and on the secondary market it is a fraction of the Gen 7 price.
Reading the throughput numbers
Firewall throughput is measured with inspection largely switched off. Threat prevention throughput is what the appliance sustains with the security services running, and it is typically a third to a half of the headline figure. Size against the second number, against your actual circuit speed.
One caveat on cross-generation comparison: the Gen 6 x600 datasheets quote anti-malware inspection throughput while the later families quote threat prevention throughput. These are not measured identically, so treat a x600 figure as indicative rather than directly comparable to a x650 or x700 one.
Transfer ready or non-transferable?
Every SonicWall we list states its registration status, because on the secondary market that matters as much as physical condition.
TRANSFER READY means the unit can be registered into your own MySonicWall account. From there you can add support, security service subscriptions and warranty, the same as a unit bought new.
NON-TRANSFERABLE means the unit cannot be moved into your MySonicWall account. It still works, and it is still managed locally through its own interface with the full configuration under your control. What you cannot do is add services, subscriptions or warranty to it. We price these as hardware accordingly, and they suit a lab, a cold spare, or a site that needs firewalling and VPN without subscription services.
At NetworkTigers, we supply refurbished, used, and new SonicWall NSA and NSa firewalls across all three families, each fully tested, serialized, and production-ready, with fast shipping and a 365-day warranty.
