SonicWall DNS Filtering Service for TZ470 4YR

Stop risky connections before they become incidents with DNS filtering for the SonicWall TZ470. This 4-year service applies policy at the DNS layer, giving security teams a fast way to block known malicious destinations, limit access to inappropriate content, and reduce the chance of users reaching high-risk sites. Because filtering happens early in the request path, it can help lower bandwidth waste and reduce the burden on downstream security controls. For teams managing distributed users or lean IT operations, DNS filtering adds a clear control point without changing the user experience. It supports consistent policy enforcement across the environment and helps standardize acceptable-use rules. The result is tighter protection, simpler administration, and a stronger security posture for the TZ470 deployment. For organizations comparing subscription options, this service is a cost-effective way to extend the value of the firewall with a control layer that works continuously in the background.
