![SonicWall High-Availability (HA) Promotion](https://www.allfirewalls.de/out/pictures/generated/category/thumb/1140_400_100/af-categorybanner-sonicwall-secure-upgrade-advanced-ha-cluster-en.png)
Avoid costly downtime at an unbeatable price - With the SonicWall HA promo, you get a high-availability appliance (secondary device) and the stateful HA upgrade license for free when you upgrade to a SonicWall NSa 2700 or NSa 3700 firewall. This ensures continuous operation of your firewall solution at all times, even in the event of a hardware failure.
With SonicWall, security services on the secondary device do not have to be licensed separately. So there are also no higher follow-up costs if you need to extend the licenses of your high-availability cluster after the inclusive license has expired.
