SonicWall TZ370 HA Unit 02-SSC-6443 | Next-Gen Firewall, HA

Protect branch operations from a single point of failure with the SonicWall TZ370 HA Unit. Built for high-availability deployments, it gives infrastructure teams a dedicated standby path so security enforcement can continue when the primary appliance needs maintenance or experiences an outage. For distributed environments, that matters. A firewall failure can interrupt VPN access, application traffic, and policy enforcement in seconds. This HA unit is intended to preserve service continuity without forcing a redesign of the security stack, making it a practical choice for teams that need resilience without adding operational complexity. The TZ370 platform is positioned for small to midsize sites that still demand enterprise-grade control at the edge. Pairing an HA unit with the primary firewall helps reduce downtime risk, support maintenance windows, and keep users connected to critical applications. It is a strong fit when the cost of interruption is higher than the cost of redundancy. Use it where uptime, policy consistency, and fast recovery matter most.
