The TZ series is a desktop firewall designed for small and medium businesses with up to 250 users. It prioritizes ease of deployment and affordability. The NSa series is a rack-mounted platform built for mid-size organizations and distributed enterprise environments, offering higher throughput, more interfaces, redundant power, and advanced SD-WAN capabilities. If your network has grown beyond 250 users or requires multi-gigabit performance, the NSa is the right step up.

A SonicWall firewall works out of the box for basic stateful packet inspection without a subscription. However, advanced features such as deep packet inspection, Capture ATP sandboxing, content filtering, and anti-malware require an active security service subscription. Firewalls.com recommends purchasing hardware bundled with an Advanced Gateway Security Suite or TotalSecure subscription to get full protection from day one.

Secure Upgrade Plus is a trade-in program that lets you replace an aging firewall from any brand with a new SonicWall appliance bundled with multi-year security services at a discounted price. You do not need to trade in a SonicWall to qualify. The program is designed to reduce the total cost of upgrading while ensuring your new device is protected from the start.

The 3 and Free promotion bundles three years of SonicWall security services with a qualifying new firewall purchase and includes a fourth year of the same services at no additional cost. It applies to select TZ and NSa models and is a cost-effective way to extend your security coverage without paying for a separate renewal in year four.

Yes. Every SonicWall firewall supports SSL-VPN and IPsec VPN for remote worker access. The TZ series supports a limited number of concurrent VPN tunnels suitable for small teams, while the NSa and NSsp series support hundreds to thousands of simultaneous remote connections. SonicWall's Global VPN Client and Mobile Connect app are available for Windows, macOS, iOS, and Android.

For most small businesses with up to 50 users, the TZ370 or TZ470 hits the right balance of performance, feature set, and price. Organizations closer to 100 to 250 users typically benefit from the TZ570 or TZ670.
