SonicWall DNS Filtering Service for NSV 470 5 Yr | Security Subscription

Extend DNS-layer protection across your NSV 470 environment with a 5-year SonicWall subscription. This service helps block access to malicious and suspicious domains before sessions are established, giving security teams a practical control point for reducing phishing exposure, malware callbacks, and other web-based risks. For organizations that prefer longer licensing cycles, the 5-year term reduces renewal overhead and supports more predictable budgeting. It also helps standardize policy enforcement over time, which matters when you are managing distributed users, multiple sites, or a security stack that needs to stay consistent without frequent administrative churn. This subscription is a strong fit when DNS filtering is part of a broader SonicWall strategy and you want a longer-lived entitlement tied to the NSV 470 platform. It adds a focused layer of protection that complements firewall controls and helps keep risky traffic out of the network path before it becomes a larger problem.
