SonicWall DNS Filtering Service for TZ270 3 Yr | DNS Security

Stop threats earlier in the connection path with DNS filtering for SonicWall TZ270. This 3-year service helps block access to malicious domains, reduce exposure to phishing and command-and-control infrastructure, and enforce acceptable-use policy before traffic reaches the network edge. For teams managing distributed users or branch firewalls, DNS-layer control adds a fast, low-friction security control that complements perimeter inspection. It can help reduce the burden on security operations by preventing risky destinations from resolving in the first place, which means fewer incidents to investigate and fewer endpoints exposed to known-bad infrastructure. This service is a strong fit for environments that want consistent policy enforcement without adding complexity to the firewall stack. It supports a more controlled browsing experience for users while helping IT maintain visibility and governance across the TZ270 deployment. For organizations comparing subscription tiers, the 3-year term offers a longer planning horizon and fewer renewal cycles, which can simplify procurement and budget management.
