Take The Worry (and the Work) Out of Web Filtering
Protecting your school or business from inappropriate Internet activity is simple and worry-free with NetFilter. Block pornography before it appears on computer screens with the click of a button. Standard categories make it easy to filter out offensive content, while flexible tools let you stop unwanted downloads and limit file sharing, IM and chat. Best of all, NetFilter analyzes web content dynamically in real-time so you don't have to constantly update black lists.
Block unwanted Web sites
Stop inappropriate, offensive or illegal content before it appears on computer screens. Block whole categories of Web sites with the click of a mouse. Select from built in content filtering categories that include: pornography, hate, racism and discrimination, violence and vulgar humour, illegal or dangerous activities, copyright violations, dating, and gambling. Augment with your own categories based on URL lists, if desired.
Reliable, continuously updated content filter
Unlike many other solutions, Netop NetFilter uses a 100% dynamic approach that is not dependent on URL lists that quickly become obsolete. This means that even new Web sites can always be reliably analyzed and filtered in real-time without any updating
Outstanding accuracy and flexibility
NetFilter reliably identifies unwanted content through a combination of industry-leading technologies for professional text and image analysis, coupled with intelligent analysis of Web surfing behavior. Custom configuration options let you adapt the software flexibly to meet school or business policies. Configure filter sensitivity, white lists, access control lists and time-specific filter settings to match your needs.
Halt instant messaging, chat and file-sharing programs
NetFilter client modules let you suppress the execution of any unwanted programs including instant messaging, chat or file sharing with the click of a mouse. Stop or set limits on streaming audio and video that consume network bandwidth.
Prevent unwanted downloads
Block inappropriate files or file types from downloading simply by specifying the file extension or fragments of the file name. Reliably block MP3 files even if the files extension is deliberately modified. Limit network load by blocking streaming media and files above a certain size.
Virtually maintenance-free operation
Use the dynamic, self-teaching filter technology and automated program updates to reduce required maintenance to a minimum.
Comprehensive logging and statistics
Log all activities and events centrally, down to user level if necessary, and view them graphically at any time. Integrate PC's outside the network using the free Business Desktop module.
Efficient administration
Use the intuitive NetFilter Admin management console to perform configuration and maintenance tasks. You can view reports and logs remotely, saving you time. The flexible user management system allows you to create multiple administrator accounts with different rights.
Highly scalable
NetFilter is scalable to meet the needs of very large businesses and school systems. Adapt the program to any network size using multiple centrally administered NetFilter installations.
