Panda GateDefender Performa allows you to restrict user access to certain Internet content through the web filtering module. This module is implemented using web content filtering technology from Internet Security Systems, a provider of security solutions.
Web filtering is based on a powerful database to block inappropriate web content. This database is stored in Panda GateDefender Performa and is automatically updated with over 100,000 new pages a day. These updates are the result of a constant daily scan of the Internet, which checks over 120 million pages per month.
This advanced technology scans online images and text. The filter is a powerful tool that identifies inappropriate web content. This allows the company to improve productivity, frees bandwidth, and protects against viruses and worms hidden in downloaded files.
The database is the kernel of the web filtering tool. It contains over 20 million URLS. These URLs are classified into 58 categories to block inappropriate web content before it reaches the network.
This database is built on sophisticated page scanning technologies in a laboratory with more than 1000 servers.
Its 20 million entries include 2.6 billion web pages. It scans over 1 billion images and is updated with 100,000 new pages every day.
Each web page is scanned using multiple scan processes in order to classify the pages as accurately as possible. The content of the database is classified into various types: websites, URLs, images and IP addresses. This database is updated every day with new pages classified by ISS' scan techniques and with pages sent by clients.
For more detailed information about the 58 categories and the criteria used to classify the pages in the database, refer to the corresponding documentation published by Internet Security Systems, in the Web Filtering products section.
