Ingate® Systems develops firewall technology and products that enable SIP-based live communication for the enterprise while maintaining control and security at the network edge. Ingate has a long history of developing next-generation firewall technology that solves the NAT/firewall traversal issue inherent in SIP communications. In addition to an extensive line of Ingate Firewalls®, the company also produces the award-winning Ingate SIParator®, a device that connects to an existing network firewall to seamlessly enable SIP communications.

For enterprises wanting to make full use of their installed IP-PBXs and not only communicate over IP within the enterprise, but also outside the enterprise the Ingate SIP Trunking module offers an easy and smooth transition to a modern and future-proofed SIP trunk provided by an Internet Telephony Service Provider to connect to the traditional PSTN network. SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces).

Ingate® Systems also offers Remote SIP Connectivity, an applications module that enables far-flung users - remote workers and home office workers - to leverage the benefits of VoIP, instant messaging, presence, video conferencing and other forms of communications based on the SIP protocol that are already integrated into the company's network.

Ingate products currently protect the networks of retail companies, financial institutions, industrial firms, government agencies and small-to-large enterprises throughout Europe, Asia and North America. Ingate Systems AB is headquartered in Sweden with offices in Stockholm and Linköping. Its wholly-owned subsidiary, Ingate Systems Inc., is located in Hollis, New Hampshire, with a U.S. technology center in Frisco, Texas. For more information on Ingate Systems, visit www.ingate.com.
