Introducing Avantguard Managed Security – WebFiltering

DNSFilter is a cloud-based, AI-driven content filtering and threat protection service. It offers a fast and reliable DNS filtering solution that protects devices and networks from cyber threats. DNSFilter’s features include:

Key Features of Avantguard Managed Security – WebFiltering:

Malicious Domain Protection

Cyber threats are constantly evolving, and traditional security measures struggle to keep up. DNS filtering solutions, such as DNSFilter, use machine learning (ML) and artificial intelligence (AI) to detect and block malicious domains in real time.

How It Works:

  • Real-Time Threat Detection: AI-powered models analyze DNS traffic and identify anomalies that could indicate phishing, malware, botnets, ransomware, or other cyber threats.
  • Proactive Security: Unlike static blocklists that require manual updates, ML-powered systems continuously adapt to detect new threats.
  • Domain Categorization: AI sorts domains into categories like malware, phishing, command & control (C2), cryptojacking, scam sites, and more to prevent access to harmful content before it reaches users.
  • Zero-Day Threat Mitigation: By detecting suspicious behavior and patterns, DNS filtering provides proactive protection against unknown threats before they are officially classified.

Benefits:
✔ Stops phishing and malware before they reach users
✔ Provides automatic, real-time updates for better security
✔ Protects against zero-day and emerging threats

Content Filtering

DNS filtering isn’t just about security—it also helps organizations manage and control the type of content that users can access. Content filtering enables businesses, schools, and institutions to enforce policies, improve productivity, and ensure compliance with regulations.

How It Works:

  • Custom Filtering Policies: Administrators can create policies to allow or block content categories such as social media, adult content, streaming services, gaming, gambling, and more.
  • User and Group Controls: Different policies can be applied to different users, departments, or devices to meet specific needs. For example, a school can restrict gaming sites for students but allow them for staff.
  • SafeSearch Enforcement: Ensures that search engines filter out explicit or harmful content automatically.
  • Time-Based Access: Allows administrators to schedule access to certain sites (e.g., blocking social media during work hours but allowing it during breaks).

Benefits:
✔ Reduces distractions and improves productivity in workplaces
✔ Ensures compliance with CIPA, HIPAA, and other industry regulations
✔ Enhances parental control for home users and educational institutions

Anycast Network

A crucial factor in DNS filtering is performance. A slow DNS service can impact internet speed for users. Anycast networking ensures fast and reliable DNS resolution, regardless of user location.

How It Works:

  • Global Network of Servers: Anycast routing means that DNS queries are automatically directed to the nearest available server, reducing latency and improving speed.
  • Load Balancing: If one server is down or experiencing high traffic, the system automatically redirects requests to another available server.
  • Built-in Redundancy: Since Anycast uses multiple geographically distributed servers, the risk of downtime is minimized.

Benefits:
✔ Improves internet speed and performance
✔ Ensures high availability and reliability
✔ Reduces latency for users worldwide
✔ Protects against DDoS attacks by distributing traffic

Intuitive Reporting

Effective cybersecurity requires visibility into network activity. DNS filtering solutions offer detailed reporting and analytics, enabling administrators to monitor traffic, detect threats, and refine security policies.

How It Works:

  • Real-Time Dashboards: Provide live updates on internet activity, including blocked requests, allowed requests, and security threats.
  • Threat Intelligence Reports: Show trends and patterns in malicious activity, helping IT teams stay ahead of emerging threats.
  • User and Device-Level Reporting: Identify which users or devices are attempting to access restricted or dangerous sites.
  • Custom Alerts: Receive notifications when suspicious activity is detected, allowing for immediate action.

Benefits:
✔ Improves incident response by identifying threats early
✔ Helps optimize filtering policies based on usage patterns
✔ Supports compliance auditing with detailed logs

Domain Categorization

To simplify content filtering and security enforcement, DNS filtering services categorize domains into different groups, making it easier to apply specific policies.

How It Works:

  • AI-Powered Classification: Domains are automatically categorized based on their content and behavior, using machine learning and threat intelligence.
  • Custom Categories: Administrators can choose predefined categories or create custom ones tailored to their organization’s needs.
  • Security-Based Categorization: Malicious domains are grouped into security-focused categories, including malware, phishing, botnets, spam, and proxy avoidance.

Benefits:
✔ Makes content filtering more efficient and flexible
✔ Enhances security by automatically blocking risky categories
✔ Helps organizations enforce compliance with industry regulations

DNSFilter Integrations

A strong cybersecurity solution needs to integrate seamlessly with existing IT infrastructure. DNSFilter provides compatibility with a wide range of platforms and services, ensuring easy deployment and management.

How It Works:

  • Cloud Security Solutions: Works with Cisco Umbrella, Palo Alto Networks, and other security platforms for enhanced protection.
  • SIEM & Log Management: Integrates with tools like Splunk and Graylog for centralized security event monitoring.
  • Endpoint Protection: Supports deployment on devices through Roaming Clients for Windows, macOS, iOS, and Android.
  • Active Directory (AD) & SSO: Connects with Microsoft Active Directory, Okta, and Google Workspace for streamlined user authentication.
  • APIs & Custom Integrations: Provides API access for custom reporting, automation, and third-party software compatibility.

Benefits:
✔ Simplifies deployment and management across IT environments
✔ Enhances security by integrating with existing security tools
✔ Provides flexible customization options through APIs and automation

How Avantguard Managed Security – WebFiltering Works

When a user attempts to visit a website, their device sends a DNS query to resolve the site’s domain name into an IP address. With DNS filtering in place, this query is checked against a set of rules or databases:

Blocklists: If the domain is known to host malicious content or falls under restricted categories (e.g., adult content, gambling), the DNS filter prevents the connection.

Allowlists: Trusted domains are permitted, ensuring essential services remain accessible.

Content Categories: Administrators can define categories of content to block or allow, tailoring access based on organizational policies.
