SonicWall DNS Security Service for TZ380 1 Yr | Cloud DNS Protection

Strengthen DNS-layer defense on SonicWall TZ380 with a 1-year DNS Security Service subscription. By inspecting and filtering domain requests before connections are established, this service helps block access to known malicious destinations, reducing exposure to phishing, command-and-control infrastructure, and other web-based threats. DNS security is valuable because it stops attacks early in the chain. Instead of waiting for a payload to download, the service can prevent users and devices from reaching risky domains in the first place. That makes it a practical control for branch offices, remote access environments, and organizations that need a lighter-weight layer of protection alongside firewall policy. This license is designed for teams that want to improve security posture without adding complexity. It fits naturally into SonicWall deployments and supports consistent protection across the subscription term. For organizations where a single malicious click can become a costly incident, DNS-layer blocking adds an efficient and defensible control point.
