SonicWall DNS Filtering Service for NSV 270, 5-Year | Security, SaaS

Stop risky connections at the DNS layer and add a critical control point to your SonicWall NSV 270 deployment. This 5-year DNS filtering service helps teams block access to malicious, suspicious, and policy-violating domains before sessions are established, reducing the attack surface without adding endpoint complexity. For organizations that need consistent enforcement across users and locations, DNS filtering provides a practical layer of protection that is fast to deploy and easy to manage. It supports security operations by turning domain requests into a policy decision point, helping limit exposure to phishing infrastructure, malware delivery sites, and other web-based threats. The value is in precision: fewer false paths, less noise, and a cleaner way to enforce acceptable use and threat prevention at scale. For teams protecting critical workloads and distributed users, this service helps maintain control where it matters most—at the first request.
