SonicWall DNS Security Service for TZ380 3 Yr | DNS Protection, Licensing

Strengthen the first line of defense on your TZ380 with SonicWall DNS Security Service. This 3-year subscription adds DNS-layer threat blocking to help prevent users from reaching malicious domains, phishing sites, and known command-and-control destinations. By filtering requests at the DNS level, it reduces exposure before a connection is established, which is especially valuable for distributed users and branch environments where every endpoint matters. Designed for organizations that want more control without adding operational complexity, this service extends protection through the firewall policy stack already in place. It helps security teams enforce consistent web access decisions, reduce incident volume, and close gaps that traditional perimeter controls can miss. For teams comparing lower-cost alternatives, the value is in the depth of prevention: fewer risky connections, less time spent on cleanup, and stronger protection for the users behind the TZ380.
