Embedded Solution Provides Stream-Based Layer 2-7 Processing To Speed
    Threat Detection

    OTTAWA, ON, June 30 /PRNewswire/ - Seaway Networks today announced the
selection and deployment of its SW5000 Network Content Processor in
StreamShield Networks' Content Security Gateway, a new security network
infrastructure device for service providers and network operators. The SW5000
is being used to supply high-speed TCP processing and packet-to-stream
conversion enabling StreamShield's product to check for multiple threats
simultaneously in real time at multi-gigabit rates and then to block those
threats before they reach subscribers.

    Key Enabling Technology

    StreamShield selected Seaway's SW5000 because of its industry-leading TCP
processing speed, customizable TCP stack, patented stream switching
architecture, easy-to-use application development environment based on the
familiar C/C++ GNU tool chain, and fully integrated functionality combining
multi-layer processing with transparent proxy and stream management software.
    These and other capabilities enabled StreamShield to significantly reduce
development time and associated costs as well as support the massive
throughput required for real-time multi-application content checking for tens
of thousands of subscribers.
    Key SW5000 features include patented silicon technology that delivers
simultaneous Layer 2-7 processing and industry-first TCP throughput of 5 Gbps
(full duplex). The solution also provides unique stream-based processing that
allows content analysis by flow rather than packet for maximum speed and
security effectiveness, the ability to apply different policies at the
individual stream level, and the ability to manage up to 2 million
simultaneous TCP connections.

    Advanced Content Processing

    In the StreamShield application, the Seaway subsystem is configured to
feed data flows to StreamShield's StreamScan engine. The StreamShield engine
then scans for and blocks viruses, worms, phishing scams, other forms of
malware, spam and inappropriate content, according to each subscriber's
individual preferences.
    For example, StreamShield's Content Security Gateway can monitor over
250,000 Web page requests per second against commercial website classification
databases, including SurfControl and the Internet Watch Foundation, and decide
to allow or block access depending on each subscriber's individual
preferences.
    The StreamShield product provides this protection for email as well as
real-time Internet applications such as web browsing, file sharing, instant
messaging, and for devices ranging from desktop and laptop PCs to mobile
phones, gaming devices, and other Internet-connected consumer electronics.

    Cure for Blended Threats

    "Seaway's SW5000 Network Content Processor has enabled us to fulfill our
vision of building a new breed of content security product that stops Internet
threats - even today's increasingly common blended threats - before they can
cause damage to the end user's computer or the enterprise network," said Jon
Curnyn, CTO for StreamShield Networks. "It is the only processing solution we
found with the features that were critical to delivering our Content Security
Gateway in its current form."
    "StreamShield's new security network infrastructure device is a striking
example of the kinds of next- generation applications that can be developed
with the powers of our SW5000," said Kit Fung, President of Seaway Networks.
"Our rapid stream-based content processing offers major advantages over
network processors that examine data packet by packet, and this translates
into new opportunities in product design."
    In addition to multi-application security gateways like StreamShield's
product, the SW5000 can be incorporated into a wide range of other OEM
products including networking equipment cards, server blades and PCI cards.
