CipherTrust’s IronMail has helped some of the largest
enterprises in the world stem the flood of spam to their end
users, as well as address a host of other e-mail threats.
IronMail’s unique Spam Profiler tool provides maximum
effectiveness by scrutinizing thousands of characteristics of
every message to determine a spam score. But the challenges for
enterprises today do not stop at identifying and blocking spam.
With spam volumes continuing to increase at an incredible rate,
the new challenge is to more efficiently handle the huge volumes
of mail, without increasing costs.
The massive growth in spam in recent years is expected to
continue exponentially well into the future. According to
Radicati Group research, the average corporate e-mail user sends
34 e-mails and receives 99 e-mails every day, a 53% increase
over numbers from just one year ago. E-Marketer expects the
total volume of e-mail sent in 2004 to exceed two trillion
messages, with steady growth rates of 13 to 15 percent annually
through 2007. With this sort of massive e-mail volume traveling
across the Internet and the reality that a vast majority is
undesired, the need for accurate and thorough spam protection
has never been greater.
To handle the additional traffic, you could add more mail
servers, or you could become smarter about how you utilize the
equipment you already have, and double your return on
investment. IronMail’s Connection Control is the first and only
offering to combine network-based traffic shaping and reputation
services to elegantly block e-mail from senders who consistently
send spam. Reputation servers and traffic shaping are both
emerging technologies in the fight against spam, and IronMail is
the first product to effectively integrate them to fight spam
and stop e-mail threats. And, Connection Control even offers an
opportunity for a little payback against spammers.
Slam the Spammer
Connection Control takes the fight to the spammers by forcing
them to spend extra time and money to send spam. By removing the
financial incentive of sending spam, IronMail forces spammers to
rethink their approach or halt operations altogether. When
dealing with spam assaults on their servers, network
administrators can choose whether to take an offensive or
defensive approach: Tough Defense – In defense mode,
Connection Control will simply not accept messages from IP
addresses flagged as violators for the designated time interval.
This vastly reduces the number of messages requiring scanning,
which lowers the cost of spam defense for the customer.
Aggressive Offense – In offense mode, Connection Control
turns the tables on spammers by accepting a connection, but
slowing the flow of e-mail to a handful of messages per hour.
This forces the spammer to expend resources despite the message
having no chance of success. In this mode, Connection Control
makes domains protected by IronMail very unprofitable targets
for spammers.
Innovation from the Leader in Messaging Security
Connection Control features several proprietary technologies
working together to help IronMail provide the fastest throughput
in the industry: Dynamic Connection Rejection – Limits
the number of messages that reach IronMail and rejects the
resources available to the offending IP address. Rejection
Intervals – By relying on data gathered by the IronMail Global
Network, CipherTrust research has determined the optimal
intervals to reject and allow connections. Anomaly Detection
Engine – Examines and controls overall traffic flow for IronMail
to identify threats. Threat Response Updates – the IronMail
Global Network comprises over 2500 IronMail units in the field.
The system provides data and updates to IronMail units as
needed. TrustedSource™ - CipherTrust’s reputation service
maintains data on millions of e-mail senders globally and
provides real-time information to IronMail appliances about a
sender’s e-mail sending behavior.
Proven in the Field
Currently in use at enterprises such as Cox Communications, Inc.
(NYSE: COX), Connection Control dynamically rejects upwards of
50 percent of connection attempts from known spammers with
dramatic results. But don’t just take our word for it. Franklin
Warlick, Cox Communications’ messaging systems administrator,
saw instant results when he installed Connection Control on
Cox’s IronMail units, which protect approximately 60,000
inboxes. “CipherTrust’s Connection Control saved us valuable
time and resources when we really needed them. This new
technology in IronMail allows us to laser in on the worst
offenders, and reject their spamming attempts at the network
edge. With Connection Control, Cox Communications was able to
reject 90,000 spam messages an hour immediately, giving us great
bang for the buck from a product that already paid for itself
many times over.”
