SonicWall DNS Security Service for TZ480 2 Yr | Cloud Licensing

Stop DNS-based attacks before they reach users and applications with a 2-year SonicWall subscription for TZ480. This service adds a security control point at the DNS layer, where malicious domains, command-and-control lookups, and suspicious resolution patterns can be identified and blocked earlier in the attack chain. For teams running TZ480 in branch or distributed environments, DNS security helps tighten policy without adding appliance complexity. It supports a practical defense strategy for organizations that want to reduce risk from phishing, malware callbacks, and domain-based threats while keeping enforcement tied to the existing SonicWall platform. This subscription is a strong fit when you need targeted protection that complements firewall inspection and endpoint controls. It is designed for environments where uptime, user productivity, and consistent policy matter more than broad, generic security claims. The 2-year term also gives procurement teams a clear planning window for renewal and budget alignment.
