What is NxFilter?

NxFilter is a free, DNS-based web filtering and network monitoring tool that helps administrators manage and secure internet usage across multiple devices. It acts as an intermediary DNS server, filtering and logging all domain requests.

When a user tries to access a website, NxFilter evaluates the request against its rules, policies, and blacklists before allowing or blocking the connection. This mechanism makes it an extremely efficient solution for controlling web access without installing software on every device.

In simpler terms, NxFilter works as a centralized network guardian that filters traffic based on categories, policies, or specific user rules—ideal for environments where internet safety and productivity are priorities.

Key Features of NxFilter 4.7.3.9

🌐 1. DNS-Based Web Filtering

NxFilter operates at the DNS level, meaning it intercepts web traffic requests before users reach the target websites. This makes it a lightweight yet powerful filtering tool that works across all operating systems without requiring individual installations.https://onlinemart.space/

🧠 2. Intelligent Category-Based Filtering

NxFilter uses intelligent web categorization to classify websites under different groups such as social media, adult content, gaming, violence, and malware. Administrators can easily block or allow entire categories, helping maintain a safe and focused online environment.

⚙️ 3. Policy-Based Access Control

With NxFilter, you can create custom policies for users, groups, or devices. For example:

Restrict social media access during work hours.
Allow educational sites but block entertainment portals in schools.
Block specific URLs or IP addresses for selected users.

This granular control ensures your network operates under defined rules and prevents misuse.

🧩 4. Active Directory and LDAP Integration

NxFilter 4.7.3.9 integrates seamlessly with Active Directory (AD) and LDAP servers, allowing automatic user identification and authentication. This means administrators can apply user-specific policies without manual setup on every workstation.https://onlinemart.space/

🔐 5. Malware and Phishing Protection

The new version strengthens threat detection capabilities by integrating updated domain blacklists and real-time threat feeds. It can block access to malicious, phishing, or command-and-control (C2) servers before any harm is done.

💻 6. Real-Time Monitoring and Logging

NxFilter provides detailed reports on user activity, including browsing history, domain requests, and bandwidth usage. The logs are presented in an intuitive web dashboard, helping administrators monitor behavior, detect anomalies, and maintain compliance.

🚀 7. Fast DNS Performance

Unlike traditional proxies, NxFilter adds minimal latency to network traffic. Its DNS-based approach ensures ultra-fast query processing, which is ideal for performance-sensitive environments such as corporate offices or data centers.

🔄 8. Automatic Updates

The 4.7.3.9 version includes an improved update mechanism that keeps your system’s threat database, domain lists, and software components current without manual intervention.

📊 9. Detailed Reporting and Analytics

The reporting module provides insights into:

Top users and most visited domains
Blocked request statistics
Category-based traffic reports
Bandwidth consumption analysis

These analytics help optimize network policies and improve overall security awareness.

⚙️ 10. Support for HTTPS Filtering

NxFilter supports HTTPS filtering through SSL inspection, enabling it to identify domain categories even in encrypted connections—essential for comprehensive web monitoring in modern environments.

How NxFilter Works

NxFilter functions as a DNS server within your network. When a device tries to visit a website:

The DNS request is sent to NxFilter.
NxFilter checks the requested domain against configured policies, blacklists, and user access rules.
If the site is allowed, NxFilter forwards the request to an upstream DNS server (like Google or Cloudflare).
If the site is blocked, NxFilter returns a custom block page to the user.

This process happens in milliseconds and allows administrators to maintain centralized control over all network traffic.

Installation and Setup

Setting up NxFilter is straightforward:

Download and Install: Run the installer on a Windows or Linux machine.
Configure DNS: Set the NxFilter server’s IP as the primary DNS for all client devices or via router configuration.
Access Dashboard: Use a web browser to log in to the NxFilter admin interface.
Define Policies: Create and assign filtering rules for different users or groups.
Monitor and Report: Review real-time logs and generate reports as needed.

Within minutes, your network is protected and manageable through an intuitive interface.
