SonicWall DNS Filtering Service for TZ470W 5 Yr | DNS Security

Protect users before a connection is ever established with SonicWall DNS Filtering Service for TZ470W, a 5-year subscription built to add DNS-layer enforcement to your security stack. By evaluating domain requests early in the connection path, it helps block access to known malicious destinations, reduce exposure to phishing and command-and-control infrastructure, and support cleaner policy enforcement across the network. For teams managing distributed users and mixed web traffic, DNS filtering adds a fast, low-overhead layer of control that complements firewall policy without requiring deep packet inspection for every request. That matters when you need stronger protection without adding unnecessary complexity to day-to-day operations. This 5-year term is designed for organizations that want predictable coverage and fewer renewal cycles. It is a practical fit for environments where uptime, user productivity, and security posture all matter at once. For TZ470W deployments, it extends the value of the platform by turning DNS into a control point for risk reduction, access governance, and threat prevention.
