SonicWall DNS Security Service for TZ480 1 Yr | Security Subscription

DNS is often the first step in a threat chain, which makes it a high-value control point. This SonicWall DNS Security Service for the TZ480 helps inspect and filter DNS activity so security teams can block access to known malicious destinations before users connect to them. That reduces exposure without changing how the network is used. For branch offices and distributed environments, DNS-layer protection adds a practical layer of defense that complements firewall policy. It can help stop command-and-control lookups, limit access to risky domains, and improve visibility into suspicious traffic patterns. Because the service is tied to the TZ480, it fits neatly into existing SonicWall deployments and keeps administration aligned with the firewall already in place. The 1-year term is a straightforward option for organizations that renew security services annually or want to align protection with budget and review cycles. It is a focused way to strengthen the edge with a service that addresses threats earlier in the attack path.
