Filtering

The filter is based on content of the Web site instead of keywords or self rating systems. This offers more flexibility to the school. Fewer sites are inadvertently blocked, encouraging relevant use of the Internet without slowing down your system or annoying the researcher by blocking sites based on words or partial words such as "association."

The Shelterbelt solution makes use of Caching Proxy, which eliminates delays to your students and staff when accessing the Internet. Because over 60% of the browser requests are already loaded on the cashing server's database, the Internet speed is visibly improved. Since the filter uses the Proxy, we are able to provide your network a greater level of security. The Proxy is much more difficult to circumvent than other tcp stream filtering systems.

Daily updates provide constant protection to your network and your students. This is by far superior to many filters that only update weekly or monthly. Since the updates are applied by the Twotrees office, you know your students and staff are protected regardless if your technology administrator had time to download updates and then apply them to your network.

The Shelterbelt filtering is customized to the level of security your district requires and is scalable. Twotrees has schools with over 10,000 users operating on one single Shelterbelt appliance.
