Content filtering is the process where content is allowed or blocked based on the analysis of the content, rather than the source or other criteria. This is particularly popular for filtering email and internet access.

Vendors that sell Content Filtering Tools
Why do you need to use an Access Technology Solution with your Content Filtering tool?
Because these tools need to be installed in-line, they can become a source of network downtime. When the device fails or needs to have maintenance performed on it, the entire network needs to be brought down to perform these fixes.
Network Critical Solutions for Content Filtering
With Network Critical’s V-Line products and their Fail-Safe technology, it is possible to install these network tools virtually In-line. If one of the connections to the V-Line TAP is lost, the other connection is automatically dropped. This will allow the network traffic to continue to flow if power is lost to the TAP or if the connected device needs to be disconnected or updated.
