SonicWall TZ570W Secure Upgrade Appliance | UTM Firewall, Wireless

Keep branch security aligned with current policy without replacing the entire platform. The SonicWall TZ570W Secure Upgrade Appliance gives eligible customers a controlled path to refresh their firewall environment while preserving the investment already made in SonicWall infrastructure. This model is sold as an upgrade-only appliance with no attached subscription, so it is designed for organizations that already maintain an active SonicProtect subscription and need a compatible replacement or expansion path. That makes it a practical choice when procurement needs to support continuity, not a greenfield deployment. The TZ570W Wireless-AC configuration adds flexibility for distributed sites where wired and wireless access must be managed under one security policy. For IT teams, that means fewer moving parts, cleaner administration, and a more predictable security posture at the edge. Choose this appliance when the goal is to maintain operational consistency, preserve licensing alignment, and keep branch protection under a known SonicWall architecture.
