SonicWall DNS Filtering Service for TZ670, 6-Year | Security, Subscription

Stop risky domains at the DNS layer and reduce the attack surface on your TZ670 deployment. This 6-year SonicWall DNS filtering service is designed for organizations that want policy-based control over web destinations without adding complexity to the firewall stack. By filtering requests before connections are established, DNS-layer protection helps block access to known malicious, suspicious, or non-compliant domains. That makes it a practical control for environments where user behavior, malware callbacks, and shadow IT can create unnecessary risk. For IT teams, the value is operational clarity: one more enforcement layer, managed through the SonicWall security environment, with a service term built for long planning cycles. For procurement, the 6-year duration supports budget stability and reduces the churn of frequent renewals. This service is a fit for organizations that need dependable, policy-driven DNS protection on the TZ670 and want to extend security coverage without overbuying hardware or adding separate point products.
