Stonesoft Introduces Internal Firewall/VPN Solution for IBM eServer zSeries Mainframes

Includes fully clustered active-active load-balancing capabilities

HELSINKI, Finland and ATLANTA -- March 6, 2006 -- Stonesoft Corp., an innovative provider of integrated network security and business continuity solutions, today announced the availability of its StoneGate™ firewall and VPN with active-active cluster functionality for the IBM® eServer® zSeries. This new release extends Stonesoft’s award-winning firewall load-balancing technology to StoneGate for zSeries mainframes by offering the industry’s first fully clustered internal enterprise firewall and VPN solution with load-balancing capabilities.

This latest enhancement of StoneGate for zSeries was developed in response to the demand in the marketplace for active-active firewall clustering and transparent connection fail over in these environments. StoneGate for zSeries fully utilizes z/VM 5.1 layer 2 functionality in order to provide active-active clustering. With StoneGate for zSeries, cluster nodes can even reside in separate mainframes and traffic can be load-balanced between them, which is useful when building hot disaster-recovery sites.

This feature is of particular importance to companies that require always-on services and for whom disruptions in connectivity are not an option. For example, financial institutions that need transactions to be flowing at all times; a disruption in connectivity while a teller is servicing a customer would have an adverse affect on customer satisfaction.
