SonicWall DNS Filtering Service for NSV 470 3-Year | DNS Security, Subscription

Stop risky domains before they become incidents. SonicWall DNS Filtering Service for NSV 470 delivers three years of DNS-layer policy enforcement for environments that need tighter control over web access and threat exposure. By filtering requests at the DNS level, it helps block access to known malicious destinations, reduce the chance of user-driven compromise, and support acceptable-use policies without adding complexity to the network stack. This service is a strong fit for organizations that want security controls close to the edge, where decisions are fast and overhead stays low. It complements firewall enforcement by adding another inspection point for domain-based threats, helping security teams reduce noise and focus on higher-value work. For distributed users, branch offices, and mixed application environments, DNS filtering can be a practical way to improve visibility and policy consistency. With a 3-year term, this subscription is designed for sustained protection and predictable planning. It is a better fit than short-term or generic filtering options when uptime, governance, and user productivity matter. SonicWall’s approach gives IT teams a clear path to extend security coverage without changing the way users work.
