Sophos PureMessage for UNIX datasheet - NwTech

GATEWAY SECURITY
Business challenge
Enterprise networks face unprecedented exposure at the gateway. As
the quantity of new threats continues to increase, so does the
speed at which they spread. Blended threats and innovative
methods of propagation increase the potential vulnerability to viruses
and spam. Failure to protect the perimeter and enforce messaging
policies – coupled with the pressure of regulatory compliance – puts
networks at risk and exposes organisations to loss of confidential
information, reduced productivity and legal liability.
The Sophos solution
Sophos PureMessage ® for UNIX provides a
secure solution at the email gateway,
uniquely integrating anti-virus, anti-spam
and policy enforcement capabilities. Based
on a scalable architecture, PureMessage
includes innovative detection techniques
that deliver proactive, sustained
protection.
Award-winning technology protects the
enterprise network from email-borne
viruses, Trojans, worms and spyware. By
countering the rapid evolution of new
spam techniques, PureMessage also keeps
inboxes free of unsolicited bulk email and
helps maintain network performance and
employee productivity. Automated tuning
technology constantly balances a range of
detection techniques to prevent protection
failures. Genotype technology blocks
families of spam campaigns and viruses,
ensuring that organisations are protected
Firewall
against previously unseen threats even
before specific detection is available.
PureMessage automatically receives the
latest anti-virus updates and new spam
rules created by expert analysts in the
SophosLabs. In addition, administrators
can implement email policies that further
reduce the risk of customer privacy,
intellectual property, and compliance
regulations being compromised.
The powerful technologies which enable
this high-level messaging security are
complemented by a range of tools that
simplify the administrative task. A
centralised quarantine and powerful webbased
administration interface enable
single point management of multi-server
systems, while the end-user interface and
digests allow end users to review
quarantine contents easily.
