SonicWall Stateful HA Upgrade License for NSA3700 - Enables Stateful Synchronization for High Availability Firewall

STATEFUL HA UPGRADE FOR NSA 3700 SERIES The SonicWall Stateful HA (High Availability) Upgrade License enables advanced stateful synchronization between two SonicWall firewalls configured in a high availability pair. With this upgrade, your HA deployment can maintain all active session data—including firewall sessions, VPN tunnels, NAT policies, and deep packet inspection state—ensuring seamless failover with no disruption to users or applications. Ideal for organizations that require high availability and minimal downtime, this license transforms a basic HA setup into a fully stateful configuration that enhances network resilience, uptime, and performance continuity. Whether you're securing a data center, branch office, or remote location, stateful HA ensures that even during device failure or reboot, connectivity is preserved without user interruption. Note: This is a software license that upgrades an existing High Availability pair to support stateful synchronization. A compatible SonicWall firewall model and configured HA setup are required. Check device and firmware compatibility before purchase.
