SonicWall DNS Filtering Service for NSA 3700, 5-Year | Security, Enterprise

Stop threats at the DNS layer and reduce the burden on downstream security tools. SonicWall DNS Filtering Service for NSA 3700 delivers policy-based domain control for five years, helping teams block access to known malicious sites, unwanted categories, and risky destinations before traffic reaches the network. That means fewer incidents to investigate and less chance of users reaching harmful content in the first place. This service is designed for organizations that want stronger web access governance without changing user workflows or adding endpoint agents. It fits naturally into existing SonicWall environments and gives administrators a practical way to enforce acceptable use policies, support compliance goals, and reduce exposure from phishing and malware delivery paths that begin with a DNS request. For infrastructure and security leaders, the value is in early intervention. DNS filtering is lightweight to deploy, easy to manage, and effective at scale across distributed users. Over a 5-year term, it provides a stable control point for ongoing protection and policy enforcement, making it a sound choice for teams that need predictable coverage and lower operational overhead.
