CipherTrust’s IronMail Spam Profiler
Tool
By Mike Rothman
VICE PRESIDENT OF MARKETING
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.”
