nFilter
MAKE THE INTERNET A SAFER PLACE TO LEARN, WORK, AND INTERACT
Netsweeper’s Carrier-Grade, Core Web and Content Filtering Platform
nFilter is a software-based web filtering platform that uses AI-driven dynamic categorization to scan, sort and analyze content in real time. Simply put, it’s the fastest, most accurate web and content filtering solution in the industry. It’s also easy to manage and deploy, adaptable to any network environment, highly customizable and cost effective.
nFilter protects users worldwide from harmful content and evolving cyber threats, while helping school districts, public agencies, telecoms and governments comply with complex regulations. As new apps, including social media, grow in number and influence, nFilter offers a flexible solution that empowers digital use and collaboration, while preventing online threats such as CSAM, ransomware and disinformation.

Protects Users with AI-Driven, Dynamic Categorization
Unlike other web filters that only detect list-based, static URLs, nFilter’s dynamic technology uses Artificial Intelligence (AI) to stop new, unknown threats proactively. It scans and filters content from billions of websites, adds this information to our unique Category Naming Service (CNS) database for categorization, then allows or denies URLs in real time, at scale. This provides the most up-to-date, accurate web and content filtering available, protecting users from unwanted or illicit content such as CSAM, cyberbullying, malware/ransomware/phishing attacks, online radicalization, and more.
Delivers Carrier-Grade Performance
Telecoms and governments need high-performance, secure web and content filtering that doesn’t contribute to network latency. nFilter delivers speed, scalability, and reliability for high- demand networks without impeding traffic or performance. As a carrier-grade solution, it’s able to support web filtering on multiple 100G links cost effectively.

Easy to Manage
nFilter gives administrators the ability to delegate management of filtering policies to teachers, managers, officials or other stakeholders within a school, agency, business, or government. This allows non-administrators, who are more familiar with day-to-day content needs of specific groups, the flexibility to assign policies that pertain to them. Central administration capabilities enable simple, universal policy management and enforcement across multiple networks, saving time and costs. In-depth reporting and dashboards provide complete visibility.

Provides Flexible Control of Social Media Access
With granular social media controls, nFilter gives administrators the flexibility to manage access to apps such as Twitter, YouTube, and Instagram. They can apply policies for specific criteria, such as age/grade level, job title, business group, and time of day, allowing appropriate or task- related access without risking compliance or productivity.
Improves Efficiency with Multi-Tenancy
As a multi-tenant solution, nFilter saves time and money related to maintenance and IT resources, increases efficiency, and simplifies overall management. Its software-based technology supports management of multiple schools, divisions, subscribers, and other user groups through a single deployed solution.
