SAN MATEO, California, June 10 /PRNewswire/ --

- Version 3.5 Enables High Performance, Multi-Stage Filtering to Counter
Spam Attacks

Bizanga, the global company behind the most scalable and full-featured
email and message processing platform, today announced the release of version
3.5 of its platform, the Intelligent Message Processor(R) (IMP).

With version 3.5 of the IMP, Bizanga introduces another market first -
true, multi-stage spam filtering for large networks. Now for the first time
ever, filtering rules at the network, protocol and application layers can be
fully integrated and managed in a single, high performance platform. By
melding the layers together, the data that's derived at one layer can be
applied real-time to others for more comprehensive and responsive spam
protection, simplified administration and improved user experience.

Multi-stage filtering has fully been integrated into Bizanga's IMP
platform and optimized for continued high performance, scalability and
reliability. Combined with the services of its application partners, it
further reinforces Bizanga's leadership in providing state-of-the-art
protection against the blended threats of spam, virus, denial-of-service and
harvest attacks.

"Bizanga's IMP represents the next generation in platforms for managing
digital messages," according to David Ferris, president of Ferris Research,
an analyst firm specializing in messaging technologies, "Two things stand out
for me: the very high level of scalability and the great flexibility that
clients have in incorporating third party messaging technology, such as
anti-spam and anti-virus."

The value of the multi-stage filtering afforded by version 3.5 is well
illustrated in two areas - network filtering and protection against
'transient spam attacks.'

With multi-stage filtering, Bizanga's customers can now block chronic
spammers even before a network connection is established (TCP/IP filtering).
Decisions can be dynamically applied based on the reputation of IP addresses
that are computed in real-time combining information on traffic patterns,
external data sources and results from Bizanga's anti-spam and anti-virus
application partners.

Previously, such functionality has been achieved through network level
systems, such as switches and routers, which typically operate separately and
require manual log processing to identify attacks. By combining network,
protocol and application layer filtering in the same system, Bizanga
considerably simplifies the administration of overall defense strategies
against spammers. The net effects are improved responsiveness and
effectiveness, reduced cost and complexity, and an enhanced user experience.

Multi-stage filtering also protects against transient spam attacks where
spammers attempt to flood a network with illicit email before traditional
content filters can detect their true nature and respond. These coordinated
attacks typically involve millions of email sent from numerous 'good' IP
addresses in just a few minutes. With version 3.5, Bizanga customers can
define rules to detect such abnormal traffic patterns, and then throttle or
sideline suspicious inbound email until their content filters can make the
appropriate disposition. These rules can be also be dynamically generated or
easily modified through the Bizanga interface to stay abreast of the latest
threats.

"Aside from the obvious benefits of operational efficiency, cost
reduction and risk mitigation," said Bizanga's chief executive officer,
JérÎme Lecat, "multi-stage filtering ensures a positive experience for the
users of Bizanga's customers and helps restore trust to the email medium. It
amply demonstrates what can be done with the 'right' platform for managing
your email communications."
