IIJ Adds New URL Filtering Service to High-Performance SEIL Series Routers

TOKYO--April 17, 2009--Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE 1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the May 2009 release of a new URL filtering function for IIJ's proprietary SEIL series of high-performance routers using NetSTAR Inc.'s Site Umpire URL filtering service.

This new feature enables URL filtering for all terminals connected to a SEIL router. Site Umpire is the market leader in URL filtering in Japan's corporate market, and it can block access to illegal websites, online gambling sites, and other sites in a total of 71 categories. Site Umpire's flexible configurations allow customers to make exceptions and allow viewing of certain sites, and it can even allow viewing while preventing posting to web-based bulletin board.

Filtering configurations can be centrally managed via the SEIL router, and when used in tandem with the IIJ SMF sx service(*1), configuration can be performed via the administrative Web interface. This feature removes the need for additional licenses and eliminate the overhead of configuring each computer on the network separately, which drastically reduces the burden involved in introducing and managing URL filtering.

The filtering database and category list is maintained on NetSTAR's server via the Internet, and the SEIL router references this server with each Internet access request to determine whether to allow the request. The filtering database is not resident on the SEIL router, thus router load is held to a minimum, and filtering is always performed with the latest database updates.

IIJ will continue its development of the SEIL series to provide new features that meet customer needs.
