SonicWall DNS Filtering Service for NSv 870 3 Yr | Security, Subscription

Stop threats at the DNS layer and keep traffic moving with a 3-year filtering subscription built for SonicWall NSv 870 environments. This service helps security teams control access to risky, inappropriate, or non-business domains before connections are established, reducing the attack surface without adding endpoint complexity. DNS filtering is a practical control for organizations that need policy enforcement without heavy infrastructure overhead. It supports consistent web access governance across users and locations, helping administrators apply rules that align with security standards, compliance requirements, and acceptable-use policies. Because the control operates at the name-resolution stage, it can help prevent users from reaching known-bad destinations earlier in the request path. For teams protecting virtualized or distributed firewall deployments, a multi-year subscription also simplifies planning. It reduces renewal churn, supports predictable budgeting, and keeps the filtering capability aligned with the NSv 870 platform over time. The result is a cleaner security posture with less manual intervention and more consistent enforcement across the environment.
