SonicWall DNS Filtering Service – 3 Year Subscription

Protect your network from evolving threats and keep your users safe with SonicWall DNS Filtering Service. This cloud-based DNS filtering solution blocks access to malicious domains and risky websites at the earliest possible stage—the DNS lookup—so threats are stopped before they can reach endpoints. By transforming domain names into safe IP addresses and applying dynamic, curated block lists, the service reduces the attack surface, minimizes data-breach risk, and lightens the load on firewalls and other security tools. The 3-year subscription delivers predictable total cost of ownership, stable protection, and scalable coverage for organizations of all sizes, ensuring precise results and continuous protection as threats evolve.

• Block threats at the source: DNS filtering operates at the DNS layer to prevent devices from connecting to known malicious domains, phishing sites, malware command-and-control servers, and other dangerous destinations. This proactive approach stops user attempts before they become traffic the firewall must inspect, reducing risk and preserving bandwidth for legitimate activities.
• Predictable, long-term value: A 3-year service duration provides stable pricing, easier budgeting, and reduced administrative overhead. With a longer license horizon, IT teams can plan security investments with confidence while maintaining strong protection against emerging threats.
• Real-time protection with continuous updates: Block lists are maintained and updated in real time based on domain names and IP addresses, ensuring rapid responses to zero-day domains, evolving phishing campaigns, and shifting attacker infrastructure. You benefit from up-to-date protections without manual reconfiguration.
• Lower firewall workload and improved performance: By handling domain lookups and policy enforcement at the DNS layer, traffic that would otherwise be subject to deep inspection is filtered earlier. This frees up firewall and security resources to focus on high-value tasks, improves latency for legitimate requests, and enhances overall network performance.
• Flexible, scalable deployment across environments: Whether you operate a single-site facility, a multi-location campus, or a distributed workforce, the service scales with your needs. It integrates with your existing SonicWall security portfolio for centralized policy management, consistent enforcement, and streamlined administration across all locations and remote users.

how to install SonicWall Dns Filtering Service

• Prerequisites: Ensure you have an active 3-year DNS Filtering Service license and access to the SonicWall management console with appropriate admin permissions to enable and configure DNS filtering.
• Activate the service: In the management console, locate the DNS Filtering section, enter the license key, and activate the 3-year subscription to enable protection across your network.
• Configure DNS routing: Point your network’s DNS queries to the DNS Filtering Service endpoints or enable the service within your DNS resolver configuration as directed by the SonicWall documentation to ensure all requests flow through the filter.
• Define initial policies: Create blocking policies by category (for example, malware, phishing, adult content, social media, etc.), and apply allow lists or exceptions for trusted domains and internal resources as needed.
• Monitor and tune: Use the management dashboard to monitor traffic patterns, review blocked requests, update block lists, and adjust policies to balance security with user productivity and business requirements.

Frequently asked questions

• What is SonicWall DNS Filtering Service? It is a cloud-based DNS filtering solution that blocks access to dangerous domains and content at the DNS lookup stage, helping prevent data breaches and reducing exposure for users and networks.
• How does DNS filtering reduce firewall workload? By filtering requests at the DNS layer, many unwanted connections are blocked before traffic reaches the firewall, freeing resources for deeper inspection of legitimate traffic and reducing processing overhead during peak periods.
• What does the 3-year subscription include? A three-year licensing term, ongoing updates to block lists and threat intelligence, cloud-based filtering, and centralized management within your SonicWall security ecosystem for consistent control.
• Can this service protect multiple sites and remote users? Yes. DNS filtering applies across locations and remote endpoints, provided DNS queries are routed through the filtering service, delivering uniform protection regardless of where users connect.
• How are updates delivered and how often are lists updated? Block lists and threat intelligence are updated in real time or near real time, with ongoing maintenance to reflect new threats, domain reputation changes, and shifts in attacker infrastructure to maintain current protection levels.
