Cerberian, a leading provider of Internet content filtering services, Thursday announced that Internet Initiative Japan Inc. ("IIJ") (Nasdaq: IIJI), a leading Internet Services Provider in the Asia/Pacific region, will begin offering the Cerberian Web Filter to new and existing IIJ customers.

Cerberian's lookup appliances have been installed at IIJ data centers in Japan. The devices provide real-time updates of new URLs, which are found on the Internet by Cerberian's proprietary search engines. These new URLs are read and rated in real-time, categorized into one of Cerberian's 55 content categories and immediately made available to all Cerberian customers.

"Millions of people rely on IIJ's Internet services, in both the corporate and retail markets in Japan," said Jeff Smith, chief executive officer of Cerberian. "Cerberian is pleased to partner with IIJ to help Japanese companies, schools and families effectively, economically and safely manage Internet usage within their organizations."

Cerberian's state-of-the-art outsourcing service monitors, filters and reports Internet activity information based on user-defined Internet policies. The service is easy to set up and requires no additional hardware investment. Since it is outsourced, there are no ongoing costs to the consumer associated with maintaining hardware and updating the databases of categorized Internet sites.

Interactive drill-down reporting is also available in real-time.

Consumers can use Cerberian's Web-based system to manage Internet activity at home, while businesses can use the service to enhance employee productivity, prevent legal liabilities and protect network bandwidth from non-productive Internet use.

"We are looking forward to using Cerberian's technology to provide new and enhanced services which our customers should find affordable, feature-rich, and easy to use and manage," said Manabu Kondo, technical planning section manager of IIJ.

"We expect the partnership with Cerberian to enhance our technological offerings and to bring a greater amount of customer satisfaction for our total network solutions services."
