SonicWall Stateful High Availability Upgrade for TZ370 - License - 1 License - TAA Compliant

Protect your network’s uptime with the SonicWall Stateful High Availability Upgrade for TZ370. This one-license upgrade unlocks advanced high-availability features for the TZ370 firewall series, delivering seamless failover, synchronized state tables, and robust redundancy essential for small to mid-sized businesses. Built to integrate with existing TZ370 deployments, this upgrade ensures your security posture remains uninterrupted during maintenance, hardware aging, or unexpected outages. By enabling true stateful high-availability, you gain automatic failover, synchronized connection tracking, and simplified management across an HA pair, so critical applications stay online and users stay productive without manual intervention.

• Unmatched uptime with active/standby HA: The Stateful High Availability Upgrade transforms your TZ370 into a resilient paired deployment. In the event of a hardware fault or routine maintenance on the primary unit, the standby unit takes over automatically, preserving existing sessions and connection states. This means minimal disruption, consistent performance, and uninterrupted access to critical services for your users and customers.
• Stateful inspection across all traffic with seamless synchronization: This upgrade ensures that session tables, NAT state, and security policies are consistently synchronized between HA peers. As a result, VPN tunnels, web and app traffic, and DPI-enabled inspections remain uninterrupted, delivering reliable security without requiring re-authentication or reconnection when failover occurs.
• Simple deployment and centralized management: Designed to integrate with your existing SonicWall management workflow, the upgrade streamlines license activation and HA configuration. You can manage licenses, monitor HA status, and verify sync health from a single console, reducing complexity for IT teams and accelerating time-to-production.
• Built for security, compliant with industry standards: The upgrade aligns with SonicWall’s security roadmap, delivering enterprise-grade availability for SMB networks. It remains TAA compliant, supporting procurement in U.S. and allied markets, and is suitable for regulated environments where reliability and traceability matter.
• Ideal for SMBs and distributed networks: If you rely on a TZ370 for firewall protection, VPN access, and filtering across locations, this upgrade provides a cost-effective path to enhanced reliability. It supports business continuity, improves user experience during failovers, and helps maintain consistent policy enforcement across your network.

How to install SonicWall Stateful High Availability Upgrade for TZ370

Upgrading your TZ370 with the Stateful High Availability License is straightforward and designed to minimize downtime. Follow these steps to activate and deploy the upgrade across your HA pair:

• Ensure both TZ370 units are installed in an HA pair and running compatible firmware. Verify that the master and standby units recognize each other and that the HA configuration is properly established.
• Acquire the Stateful High Availability upgrade license key from your SonicWall account or authorized vendor. Confirm that the license corresponds to the TZ370 model and your existing HA configuration.
• Log into the SonicWall management interface on the primary firewall (the active unit in the HA pair). Navigate to the Licenses and Subscriptions section to add or activate the new Stateful HA upgrade license key.
• Apply the license and follow any on-screen prompts to complete activation. If prompted, perform a reboot or HA resynchronization to ensure the upgrade is properly applied across both HA peers.
• Verify HA status and synchronization after activation. Check that session tables, firewall rules, VPN sessions, and DPI features are consistently mirrored on both units. Conduct a controlled failover test to confirm seamless transition and uninterrupted service.
