SonicWall DNS Security Service for TZ280W 5 Yr | Cloud Security

Protect the DNS layer on a SonicWall TZ280W with a 5-year security service built to intercept threats early. DNS Security Service helps block access to malicious destinations before a connection is established, reducing the chance that users reach phishing sites, command-and-control infrastructure, or other harmful endpoints. For teams that want a cleaner security stack, DNS-layer control adds an efficient control point without adding complexity at the firewall. This long-term subscription is a strong fit for organizations that prefer fewer renewal events and more predictable protection planning. By extending coverage across five years, it helps reduce administrative overhead while keeping DNS security active on the appliance that already sits at the network edge. That matters in branch environments where security gaps often appear when subscriptions lapse or are managed inconsistently. Choose this service when you want to keep the TZ280W aligned with modern threat conditions and maintain a stable, cloud-delivered layer of defense over time.
