SonicWall DNS Filtering Service for TZ670 1 Yr | Security Subscription

Stop risky DNS requests at the first point of contact. SonicWall DNS Filtering Service for TZ670 1 Yr adds cloud-delivered domain filtering to your TZ670 firewall, helping security teams reduce exposure to phishing, malware, and other web-based threats before connections are established. This subscription is built for organizations that want stronger control without adding operational drag. Policy-based filtering lets you define acceptable access, block known-bad destinations, and apply consistent rules across users and locations. Because DNS filtering works upstream of the web session, it can reduce unnecessary traffic, improve user safety, and support cleaner incident response. For teams standardizing on SonicWall, this service extends the value of the TZ670 with a focused security control that is easy to deploy and maintain. It is a practical choice when you need more than basic firewall inspection and want a dedicated layer for domain-level threat prevention. The 1-year term fits planned refresh cycles, annual budgeting, and subscription-based security procurement.
