How to Choose the Right SonicWall Firewall

What size is your network?

The TZ series (TZ270, TZ370, TZ470) serves small offices and branch locations with up to 150 users. The NSa series (NSa 2700, NSa 3700) covers mid-size organizations with 250-2,000 users. The NSsp series handles large enterprises and data centers with multi-gigabit threat prevention.

Wired or wireless?

Many TZ models come in a "W" variant with built-in 802.11ac WiFi, eliminating the need for a separate access point in small offices. Larger deployments should use dedicated wireless access points managed separately.

Which subscription do you need?

SonicWall firewalls require an active subscription for full security features. Essential Edition covers basic threat prevention. Advanced Edition adds cloud sandboxing (Capture ATP) and content filtering. Match the subscription tier to your compliance and security requirements.

Frequently Asked Questions

What is included with a SonicWall firewall purchase?

The hardware appliance is sold separately from security subscriptions. Some bundles include the hardware plus a 1, 2, or 3 year subscription (Essential or Advanced Edition). Without an active subscription, the firewall still provides basic stateful packet inspection, VPN, and manual firewall rules, but not real-time threat intelligence.

What is the difference between the SonicWall TZ and NSa series?

The TZ series is designed for small to mid-size offices and branch locations (up to about 150 users) with firewall throughput up to 4 Gbps. The NSa series serves mid-size to large organizations (250-2,000+ users) with firewall throughput up to 12 Gbps and higher concurrent connection counts.

How often do SonicWall subscriptions need to be renewed?

SonicWall security subscriptions are typically available in 1, 2, or 3 year terms. When a subscription expires, the firewall continues working for basic packet inspection and VPN but stops receiving threat signature updates, cloud sandboxing, and content filtering until renewed.
