iPrism: More Than a Network Device or Software, Combined. iPrism is an Internet monitoring software appliance...

It is a separate piece of hardware installed onsite. With integrated Internet monitoring software and databases, iPrism is more than hardware or software filtering alone. iPrism provides a dedicated resource for Internet monitoring with simple network integration. iPrism also has the flexibility and configurability of Internet monitoring software while having a centralized way to manage configuration and to filter traffic, without having to purchase separate servers or support software to get enterprise-level filtering.

Hardware-based Internet monitoring has an advantage in working well in multi-platform network environments and with multiple servers because hardware Internet filtering usually involves reconfiguring the firewall to block IP addresses. However, hardware solutions lack flexibility and fine-grained control over how to block sites because entire IPs or domains are blocked without any differentiation between individual sites on those IP addresses.

Internet monitoring software grants more control over filtering because it takes a content-aware approach, usually by using keywords to identify sites. Internet monitoring software can also be configured to allow different filters for groups of people. There are two major disadvantages to Internet monitoring software. First, Internet monitoring software can be difficult to implement in mixed environments, on wide-area networks, or on multiple desktops because software control is local, not centralized. Second, the effectiveness of the Internet monitoring software depends heavily on the filtering methods used; keyword recognition alone can have lots of false positives and negatives and can miss image-rich sites, like many pornographic sites.

Because iPrism is a filtering appliance, it has the easy integration of hardware with the flexibility and control of Internet monitoring software filters:
  • Transparent network configuration. iPrism is simply plugged inline with the firewall, and all traffic for all protocols and ports on the network, inbound and outbound, is filtered. This Internet monitoring software protects the network from the perimeter, so dangerous requests are blocked before they ever reach your web servers.
  • Platform independent. iPrism works on the network, not individual servers or computers, so it doesn’t matter what operating systems you have. iPrism Internet monitoring software works with all versions of Windows, Unix, Linux, and Mac.
  • Centralized configuration. iPrism uses a simple web interface to configure Internet monitoring software. Even if there are multiple Internet monitoring software appliances, a single, consistent policy can be applied to all appliances through a single configuration interface.
  • iGuard database. The iGuard database combines keyword filtering with 100% human review to classify the content and context of every individual URL. Categories are updated with new sites as often as every hour, so the Internet monitoring software is always current.
