Top 10 Features of NxFilter-Cloud You Should KnowNxFilter-Cloud is a cloud-based DNS filtering and security platform designed to protect networks from malicious domains, enforce acceptable-use policies, and provide visibility into DNS traffic. Whether you’re an IT administrator for a small business, a school district, or an enterprise, understanding the core features of NxFilter-Cloud will help you deploy and operate it more effectively. Below are the top 10 features you should know, why they matter, and practical examples of how each can be used.
1. Cloud-based DNS Filtering and Policy Enforcement
What it does: NxFilter-Cloud routes DNS queries through a managed cloud service that applies filtering policies in real time.
Why it matters: Being cloud-based removes the need to maintain on-premises DNS filtering infrastructure, simplifies scaling, and reduces management overhead.
Practical use: Point client networks to NxFilter-Cloud DNS resolvers (or forwarders), then create policies to block categories like malware, phishing, or adult content. This enforces company or school acceptable-use rules without installing software on each device.
2. Category-based and Custom URL Blocking
What it does: Provides a comprehensive categorization engine for domains (e.g., malware, social media, streaming, gambling) plus the ability to whitelist or blacklist specific domains or subdomains.
Why it matters: Category filtering lets administrators quickly apply broad policies, while custom lists handle exceptions and special cases.
Practical use: Block streaming and social categories during work hours but whitelist company collaboration domains and partner sites.
3. Real-time Threat Intelligence and Malware Protection
What it does: Integrates threat intelligence feeds and maintains updated blocklists to prevent access to known malicious domains.
Why it matters: Blocking DNS lookups to malicious infrastructure stops many threats before a connection or payload is established. It’s a lightweight, effective layer of protection.
Practical use: Prevent devices from resolving command-and-control (C2) domains used by botnets, reducing infection spread and data exfiltration risk.
4. Granular User/Group-based Policies
What it does: Allows policies to be assigned by user, device, IP, subnet, or group (integration with directory services may be supported depending on plan).
Why it matters: Different users and groups require different levels of access—students vs. teachers, contractors vs. employees. Granular policies enable tailored filtering with minimal friction.
Practical use: Apply stricter browsing restrictions to guest networks while giving IT staff full access for troubleshooting.
5. Reporting, Logging, and Analytics
What it does: Captures DNS query logs, categorizes activity, and provides dashboards and reports showing trends, top queries, and policy hits.
Why it matters: Visibility into DNS activity helps identify malicious behavior, enforce compliance, optimize policies, and justify security investments.
Practical use: Use weekly reports to show leadership which categories consume bandwidth or to investigate suspicious peaks in lookups to unknown domains.
6. Easy Deployment and Integrations
What it does: Supports simple deployment by changing DNS settings, using DHCP to distribute resolvers, or integrating with existing DNS infrastructure via forwarding. It often offers APIs and integrations for automation and SIEMs.
Why it matters: Quick deployment reduces time-to-protection and allows integration into existing workflows and tooling.
Practical use: Configure DHCP to hand out NxFilter-Cloud DNS IPs to all devices on the network, or set up conditional forwarding from an on-prem resolver.
7. TLS/HTTPS (DoH/DoT) Support and Privacy Controls
What it does: Supports encrypted DNS protocols (DNS over HTTPS and DNS over TLS) to protect query confidentiality and resist on-path interception. Privacy controls may allow selective blocking of these protocols or policy enforcement over them.
Why it matters: Encrypted DNS prevents eavesdropping and tampering of DNS traffic while maintaining filtering effectiveness when supported.
Practical use: Allow DoH for remote users while ensuring their queries still route through NxFilter-Cloud to apply corporate policies.
8. Customizable Captive Portal and Block Pages
What it does: Displays user-facing block pages or captive portals with messages, policy reasons, and options (e.g., request access). These can be customized with branding and contact info.
Why it matters: Clear block pages reduce confusion, support policy compliance, and provide users a path to request exceptions.
Practical use: Show a branded block page explaining that a site is blocked by policy and include a one-click request form to notify IT.
9. Redundancy, High Availability, and Global Reach
What it does: As a cloud service, NxFilter-Cloud typically runs across multiple regions and edge nodes to ensure fast DNS resolution and resilience to outages.
Why it matters: High availability ensures continuous name resolution and filtering even if one data center or node experiences issues. Global points-of-presence (PoPs) reduce latency for distributed organizations.
Practical use: Remote offices and traveling staff experience consistent performance because queries route to the nearest NxFilter-Cloud PoP.
10. Role-based Administration and Multi-tenant Support
What it does: Offers role-based access control (RBAC) so administrators can delegate permissions and supports multi-tenant setups for MSPs or large organizations managing multiple sites/clients.
Why it matters: RBAC reduces risk by assigning only necessary privileges; multi-tenant features simplify management for service providers and large distributed organizations.
Practical use: Give help-desk staff the ability to create exception rules while restricting billing and account changes to senior admins; an MSP can manage multiple customer accounts from one console.
Conclusion NxFilter-Cloud combines DNS-level security, policy enforcement, and operational simplicity. Its core strengths are low-friction deployment, category-driven controls, threat intelligence-driven blocking, and usable reporting — all delivered from a resilient cloud platform. When evaluating DNS filtering solutions, prioritize features that match your environment: whether it’s granular user policies, DoH/DoT support, or an MSP-friendly multi-tenant console.
