SonicWall DNS Filtering Service for TZ570W 3-Year | DNS Security, Subscription

Keep domain-based threats out of the path of your users. SonicWall DNS Filtering Service for TZ570W adds three years of DNS-layer control to help block access to malicious destinations, enforce web-use policy, and reduce the chance that users connect to risky infrastructure. It is a practical security layer for organizations that want faster decisions at the edge without adding operational burden. DNS filtering is especially valuable where visibility and control need to extend beyond traditional perimeter rules. By evaluating requests at the DNS level, this service helps security teams reduce exposure to phishing, malware delivery, and command-and-control domains while keeping policy enforcement consistent across users and locations. For branch offices, distributed teams, and mixed network environments, that means tighter control with less complexity. The 3-year subscription term supports stable planning and sustained protection. It is a strong fit for teams that want a longer service horizon and a security control that complements the TZ570W platform. Compared with basic filtering approaches, this service is built to add meaningful policy enforcement where it matters most: before a connection is made.
