Introduction
Implement a web security policy
Web filtering enables you to establish a formal web security policy
This allows managers to ensure appropriate use of the Internet. It protects the network against viruses and phishing attacks by preventing user access to inappropriate sites. As a result, employee productivity also increases, which is further reflected in your ROI.
NETASQ’s parallel processing algorithm guarantees optimum access speeds and an improved user experience.
Automatic updating of web filter databases are included within our support contracts.

Not surprisingly, company employees spend a significant proportion of their time at work surfing the web. This is often at great expense to enterprises; for example if a business has 100 employees who all spend an hour a day surfing non-work-related sites the total cost to the business is close to €400,000 a year.
However, this is not the complete picture as the degradation of network performance should also be reflected in the cost. In fact, businesses carry an overhead of as much as 60% of non-work related traffic on their networks. There is also significant risk to a company’s reputation, as users may download inappropriate content.
Of even greater concern is the threat caused by malicious applications, often introduced inadvertently while surfing leisure sites. These can collect personal information, take control of a user’s computer and redirect web browser activity. To counter these threats and increase productivity, enterprises need to be able to manage network traffic and block access to inappropriate content.
NETASQ’s URL filter enables organizations to block specific websites, without interfering with employee access to appropriate sites and their day to day work.
Every NETASQ firewall includes an integrated URL filter which identifies and classifies millions of websites.
NETASQ regularly scans a range of data sources to update the URL database using a processing algorithm, present in NETASQ’s intrusion prevention engine. The database is fully optimized for real-time viewing.
