Ingate to Distribute IM-Capable Firewalls Through ICS
July 23, 2002
By Bob Woods

Ingate Systems, which produces SIP-capable firewalls and SIParators, said its mission-critical security products are now available through Interlink Communication Systems (ICS), a Clearwater, Fla.-based value-added reseller (VAR).

Sweden-based Ingate produces session-initiation protocol (SIP)-capable firewalls and SIParators -- a device that plugs into an existing firewall to seamlessly enable SIP -- for enterprises that want the time and money saving benefits of SIP-based real-time communications including presence, instant messaging (IM), VoIP and conferencing.

SIP, or Session Initiation Protocol, is the Internet Engineering Task Force (IETF) signaling protocol that allows interoperable real-time communications regardless of who is providing the service. Providers including Microsoft, AOL, AT&T, MSN, Yahoo, Cisco Systems, Pingtel and CommWorks are either already offering or are developing SIP-based products and services. Some predict it will only be a matter of time before SIP is for real-time communications what HTTP is for the Web.

Because SIP is a new protocol, though, existing firewalls currently block SIP media streams. Ingate's technology allows SIP to interoperate with existing installed firewalls.

Ingate's suite of firewalls and SIParators are available in a range of models to meet the needs of the entire enterprise market. All include a SIP proxy and a SIP registrar, support NAT and PAT and have TLS support for encrypted SIP signaling, which means that instant messages are automatically encrypted, eliminating IM security concerns.
