SonicWall DNS Filtering Service for TZ470 3 Yr | Security Subscription

Stop threats at the DNS layer and reduce exposure before a connection is ever established. SonicWall DNS Filtering Service for TZ470 delivers 3 years of policy-based domain control for environments that need tighter internet governance without adding appliance complexity. By filtering requests to known malicious, suspicious, or inappropriate destinations, this service helps security teams cut down on phishing, malware delivery, and shadow IT access. It also gives administrators a practical way to align browsing behavior with corporate policy, compliance requirements, and acceptable-use standards. For organizations running TZ470 at the edge, DNS filtering adds a high-value control point that works early in the traffic path. That means fewer risky sessions, less noise for downstream security tools, and more consistent enforcement across users and locations. It is a strong fit for teams that want measurable risk reduction from a lightweight subscription rather than a heavier stack of point products.
