SonicWall DNS Filtering Service for NSA 5700, 5-Year | Security

Protect critical users and workloads by filtering DNS requests before they resolve into risky connections. This 5-year SonicWall service for the NSA 5700 adds a control point that helps block access to known malicious, inappropriate, or non-compliant domains without waiting for downstream inspection to catch the problem. For security teams, DNS filtering is valuable because it reduces attack surface early in the session flow. It can help stop phishing destinations, command-and-control lookups, and other unwanted web access while giving administrators a practical way to apply policy across the organization. That means fewer incidents to investigate and less time spent cleaning up preventable exposure. This service is a strong fit for environments that need more than basic perimeter filtering. It supports a layered defense strategy where DNS becomes an enforcement point, not just a lookup service. Over a 5-year term, it also aligns protection with long refresh cycles and budget planning, making it easier to standardize security coverage on the NSA 5700 platform.
