SonicWall DNS Filtering Service for NSA 6700 4YR | DNS Security

Stop harmful domain requests before they become active connections with DNS filtering for NSA 6700. This 4-year SonicWall service adds a network-level control point that can block malicious domains, support acceptable-use policies, and reduce exposure to phishing infrastructure and other risky destinations. DNS-layer filtering is especially useful in environments that need strong protection with minimal disruption. It works without changing the user experience and without requiring endpoint agents, which makes it easier to deploy across office networks, guest access, and distributed users. For security teams, that means better visibility into domain activity and a cleaner way to enforce policy at the edge. The longer 4-year term is a practical fit for organizations that want stable coverage and predictable protection over a multi-year refresh cycle. For SonicWall NSA 6700 deployments, this service extends the value of the platform by adding a focused security layer that helps reduce attack surface and support more controlled internet access over time.
