It's important that the technology you choose for Web filtering not only performs well, but helps you achieve your larger goals of keeping the network secure while not interfering with the systems you have in place now. In choosing the right Web filter, technology is critical. Here is a list of factors you should consider in procuring a Web filter for your organization:

Easy to Deploy: A Web filter that is easy to install, configure and maintain can conserve valuable IT resources needed to keep your networks and systems in top condition. Appliance-based filters that install at the perimeter can eliminate the need for complex integration with your OS and other systems.

Easy Authentication: Nothing can slow down your admin duties more than having to manually authenticate users. A Web filter with seamless directory integration that works with AD03 to AD08, LDAP and even MAC, makes authenticating users simple and fast - you can do it from any computer with browser access. If you are using Citrix. you will want to be sure the Web filter you choose is Citrix authorized. Only a Web filtering appliance with session-based authentication can offer Citrix compatibility.

Self-contained Solution: A Web filter with its own hardened and optimized OS assures complete interoperability with any legacy system or mixed platform you may be running. A self-contained technology means a single point of failure should there be a problem - no hunting for issues with your servers or other systems and devices.

Kernel-level filtering: Look for a filtering technology that offers optimal speed and accuracy. While most URL filters process requests from the application layer, using the kernel layer shortens the process because requests are first passed through to the Internet and then allowed or blocked on their way back. This combination of pass-by and pass-through technology allows maximum accuracy with zero latency. This means a better Web experience for users and fewer helpdesk calls for you.

Built on FreeBSD: A Web Filter based on FreeBSD offers more security and compatibility than many other operating systems in use today. It also allows the Web filter to operate continuously and without latency.

Multiple Deployment Scenarios: A Web filter that is deployed in transparent bridge mode will provide the easiest installation because it won't require you to alter your existing firewalls and/or routers. However, the Web filter you choose should be flexible enough to allow proxy mode, if needed. A self-contained, appliance-based Web filter that is flexible enough to work in a variety of complex or legacy networks, and one that can integrate with your specific and non-standard requests, will assure you get the maximum performance from your Web filter without compromising your network.
