SonicWall DNS Security Service for NSSP 15700 5-Year | Enterprise

Strengthen DNS-layer defense for NSSP 15700 environments with a 5-year SonicWall DNS Security Service. This subscription is built for teams that need sustained protection against domain-based threats, phishing infrastructure, and other DNS-driven attack paths that often bypass perimeter-only controls. By adding DNS security at the network layer, security teams gain another control point for blocking risky destinations before they can reach users or endpoints. That matters in environments where a single compromised click can create outsized operational and financial impact. The long service term also supports cleaner budgeting and reduces the churn of annual renewals, which is especially useful for enterprise security programs with multi-year refresh cycles. For organizations standardizing SonicWall across distributed sites, this service helps keep policy enforcement consistent while preserving visibility into DNS activity tied to threat detection and response. It is a practical choice when the goal is to reduce attack surface without adding complexity to daily operations. The result is more durable protection for a critical control plane, backed by a service term that matches enterprise planning horizons.
