Hardware Specifications

• Ports: 8× 1 GbE, 2× USB 3.0, 1× Console port

• Form Factor: Desktop, rack mountable

• Firewall Throughput: ~2 Gbps

• Compact and lightweight design suited for SMB and distributed branch environments.

Key Features

High Availability (HA) Functionality

• Active-Standby configuration: the HA unit stays in standby and automatically takes over if the primary TZ270 fails, then returns to standby when the primary recovers.

Security & Performance

• Stateful Next-Generation Firewall (NGFW) with advanced threat protection features (depending on licenses you attach to the primary).

• Can support real-time Deep Packet Inspection, IPS, anti-malware, and other security services if licensed on the primary unit.

Enterprise-Class Security

• Built on Gen-7 SonicWall architecture with SonicOS 7 firewall/security operating system.

• Supports advanced threat protection services (when paired with a licensed primary): intrusion prevention (IPS), anti-malware, deep packet inspection and more.

• Secure SD-WAN support for improved WAN performance and resiliency.

Performance & Throughput

• Up to 2 Gbps firewall throughput — maintains strong performance even in failover scenarios.

• 750 Mbps threat prevention throughput — enabling deep inspection and blocking of threats.

Connectivity & Interfaces

• 8 × 1 GbE ports, plus USB and console connectivity for flexible deployment.

• Supports standard networking features such as VLANs, routing, VPN connectivity (handled by the primary TZ270).

Deployment & Management

• Zero-Touch Deployment — simplifies rollout in distributed sites.

• Works with SonicExpress App for onboarding and has comprehensive management options via UI, CLI, API.

Storage & Expandability

• Built-in and expandable storage (up to 256 GB) — supports logging, reporting, firmware backup and caching.

Auxiliary Features

• Designed for small- to mid-sized businesses and SD-Branch use cases.

• Shares the primary unit’s security licenses — ensuring full protection coverage in active or standby roles.

Use Cases

✅ Small to Mid-Size Businesses
Ideal for environments where uptime is critical but budget and space are limited.

✅ Branch Networks / Distributed Sites
Useful in multi-branch deployments where remote sites require continuous security without on-site IT staff.

Conclusion

The HA unit does not function standalone. It must be paired with a primary SonicWall TZ270 firewall and (if desired) the matching licensed security services on that unit.
