SonicWall DNS Security Service 5-Year for TZ280 | DNS Protection

Strengthen DNS-layer defense for SonicWall TZ280 environments with a 5-year security service subscription built to intercept risky lookups before they turn into incidents. DNS security is a practical control point for organizations that want to block access to malicious domains, reduce the chance of user-driven compromise, and add another layer of protection without changing the network design. This service is a strong fit for teams that already standardize on SonicWall and want to extend protection beyond traditional firewall rules. It supports a more controlled browsing and resolution path for users, helping security teams reduce exposure to phishing infrastructure, malware delivery sites, and other DNS-abuse techniques. Because this is a service subscription rather than hardware, it carries no physical footprint and no rack requirements. The 5-year term is well suited to organizations planning longer refresh cycles or multi-year security budgets, especially where predictable coverage and vendor alignment matter more than one-time licensing.
