SonicWall DNS Security Service for TZ380W 5-Year | DNS Filtering, Enterprise

Protect users at the DNS layer, where many attacks begin. SonicWall DNS Security Service for TZ380W adds cloud-delivered domain intelligence and policy enforcement to help stop access to known malicious destinations before a connection is established. That means fewer successful phishing clicks, less malware delivery, and tighter control over outbound traffic from the edge. Built for organizations standardizing on the TZ380W platform, this 5-year service extends security coverage without changing the firewall footprint or adding endpoint agents. It is a practical fit for teams that want stronger prevention at the network perimeter while keeping administration centralized. DNS-layer controls are especially valuable for distributed environments where users may move between offices, remote locations, and unmanaged networks. For infrastructure teams, the value is straightforward: reduce risk early in the kill chain, enforce consistent policy, and preserve bandwidth and analyst time by blocking threats before they generate downstream incidents. This subscription is designed for buyers who need durable protection over a multi-year planning cycle and want a security layer that complements existing firewall controls.
