real-time connectivity to a scalable cloud-based repository, providing
auto-updated classifications.
- High accuracy on classification algorithms for the database.

correctly identified.
- Classification by page- Globalview will parse the whole URL to categorize
different sections within a website.
- Embedded links checking– Prevents bypassing web controls by using parsing
or translating websites.
Mechanism for Commtouch GlobalView URL Filtering (URLF)
- The DrayTek router receives a http request from a user.
- The router queries the GlobalView server to check the URL classification.
- The GlobalView URL engine built into the router checks its local cache for
URL values; typically more than 99% of queries are locally resolved by the
cache.
- If necessary, the GlobalView URLF engine queries the Commtouch Detection
and Classification Centre for relevant updates.
- The router blocks, allows or strips content according to the class
classification it receives from the GlobalView URLF engine and the
configuration of the WCF.
Overview
DrayTek’s Web Content Filter (WCF) blocks undesirable web content based on
the configuration in the router. Any web site browse request is compared with a
URL Filtering database provided by Commtouch’s GlobalView WCF which is updated
in real time through the Cloud.
GlobalView classifies all websites around the globe into 64 categories that
can be selected to be either blocked or permitted and be applied to the required
user groups. For example, children at home can be prevented from accessing adult
sites, or employees in the workplace can be restricted from accessing unrelated
social networking sites during work hours.
Since website contents are constantly changing, GlobalView URL Filter is also
continuously being updated to ensure on-going accuracy and protection to users.
Reason to Block Example
- Potential threats
- Anti-productivity
- Child protection
- Illegality
- Bandwidth Regulation
- Websites containing viruses, malware, phishing and zombies/bots, etc.
- Unproductive or unrelated sites for employees’ e.g. social networking.
- Adult material for children e.g. pornography, gambling.
- Illegal material downloading sites
- Unrelated website traffic, e.g. movies, music, etc., that consume network
bandwidth of the organisation.
