NetOp Netfilter - Functionality

A unique combination

With the output from a unique combination of image analysis, text analysis and a historical behavior analysis fed into an artificial intelligence decision engine, NetOp Netfilter analyzes web content in real-time and applies rules on the fly. And it does it 100% dynamically, with no need for updates.

Image analysis

NetOp Netfilter is one of the only filters that utilize image analysis. Most sites with offensive contents have a high image-to-text ratio. NetOp Netfilter uses its high precision and fast image analysis to analyze and block offensive or inappropriate content. By examining a range of features in an image such as shape, color and faces, Netfilter correctly blocks unwanted images while non-offensive images are allowed.

Text analysis

NetOp Netfilter also analyses the text in real-time in order to provide an even more precise solution. Many languages are supported including English, Spanish, German, French and the Nordic languages. Individual words as well as sentences and page setup are analyzed for maximum precision. PICS™ labels are also evaluated.

Behavior analysis

NetOp Netfilter uses historical behavior analysis to track behavior of the individual user to further increase the precision of the content categorization.

Artificial intelligence

Because of the complexity in analyzing images, text and behavior, NetOp Netfilter utilizes an state-of-the-art artificial intelligent decision engine, developed and trained to correctly distinguish between the different categories, hence between inappropriate and relevant content.

Dynamic content filtering

NetOp Netfilter analyses web content in real-time without consulting a black list of disallowed pages. By using a dynamic engine, NetOp Netfilter can block existing web content as well as those of tomorrow. NetOp Netfilter does not require constant updates to cope with the many new offensive sites that are introduced to the Internet each day.
