SonicWall DNS Security Service for TZ580 5 Yr | Threat Protection

Protect the TZ580 with DNS-layer security designed to intercept threats early, before they can resolve into active connections. This 5-year service adds a critical control point for environments that need stronger protection against phishing, malware callbacks, and domain-based command-and-control activity. By filtering malicious DNS requests, the service helps reduce exposure without adding complexity to the network stack. It is a practical fit for organizations that want to strengthen security posture on the firewall they already trust, while keeping policy enforcement close to the edge. For teams responsible for uptime, user safety, and incident reduction, DNS security adds a valuable layer of defense that complements perimeter controls. It is especially useful where users move between offices, remote access, and cloud applications, and where a single malicious lookup can become the first step in a broader compromise. This 5-year term is built for long planning cycles and predictable protection. It supports a more disciplined security model for the TZ580, helping IT teams maintain consistent coverage without frequent renewal churn.
