SonicWall TZ570 Secure Upgrade Appliance | Firewall Upgrade, Enterprise

Maintain continuity in your SonicWall security stack with the TZ570 Secure Upgrade Appliance. This product is designed for existing SonicWall customers who need an upgrade path for an eligible appliance rather than a fresh standalone deployment. That distinction is important in enterprise procurement. When the firewall platform still matches the network design, the right move is often to extend coverage and preserve operational consistency instead of forcing a hardware refresh. This upgrade appliance supports that approach, helping teams keep protection aligned with policy, support, and lifecycle requirements. The TZ570 Secure Upgrade Appliance is only eligible as an upgrade to an existing SonicWall appliance with an active SonicProtect subscription. It is not sold as a new subscription bundle, and it is not intended for first-time deployments. For organizations managing standardized SonicWall estates, that makes it a precise fit: less disruption, clearer renewal planning, and a cleaner path to keep security infrastructure in service.
