SonicWall DNS Security Service for TZ380 4 Yr | DNS Protection, Licensing

Strengthen SonicWall TZ380 with DNS Security Service and add a control point that works before a connection is made. This 4-year subscription helps filter DNS requests against threat intelligence and policy rules, reducing the chance that users reach malicious domains, phishing infrastructure, or other risky destinations. DNS-layer protection is valuable because many attacks begin with a simple lookup. By stopping that request early, the service helps limit exposure without depending only on payload inspection or endpoint response. It is a practical fit for organizations that want consistent protection across offices, branches, and remote users. For teams standardizing on TZ380, this service extends the firewall’s security posture with a subscription model that is easy to plan and renew. It adds a focused layer of defense that supports cleaner policy enforcement and a lower-risk browsing environment for everyday operations.
