Highly

The Barracuda Spam Firewall’s robust and scalable design enables
it to handle email networks of over 10,000 active email users.
It can process over 10 million email messages per day. That
is a lot of email. We have different models for different
mail loads. Multiple Barracuda systems can be employed and
easily configured for redundancy or additional load capability.

Deploying the Barracuda Spam Firewall is easy. Just plug in
your Barracuda Spam Firewall, accept our default settings
or make any changes you’d like and you’re ready to go. There
is no software to install. There are no modifications to your
existing system. It’s that easy. Most customers are up and
running in only 5 minutes.
Independent network device dedicated
to spam-blocking
The Barracuda Spam Firewall is a self-sufficient networking
device that handles all your spam-blocking so it does not
bog down your email servers. In fact, with the Barracuda Spam
Firewall, the load on your email system is actually reduced.
Your email servers will process and store less incoming email.
The performance of your email servers will increase.
Blocks spam using proven methods
By using all the best methods to block spam, the Barracuda
Spam Firewall provides comprehensive spam-blocking for your
company. Below are the primary algorithms we employ to block
spam. We generally recommend targeting approximately 97% blockage.
However, we provide a number of parameters that can be adjusted
if necessary.

• |
Blacklisting
of websites & domains: Barracuda Central
maintains an up to date list of the largest and most
aggressive known spammers. This list is maintained by
both Barracuda and other anti-spam groups. This list
is automatically updated on each Barracuda Spam Firewall.
|
| |
• |
Keyword
scanning of emails: This can be configured
on a per user basis. Our scanning methods include a
scoring system such that emails are scored based on
a number of criteria. If the score is above a threshold,
then that email is flagged as spam. The Barracuda Spam
Firewall comes with default criteria and thresholds
but you may change these. |
| |
• |
Checksum
technology: Barracuda Central monitors email
traffic through the Internet and uses checksum technology
to keep track of the number of times a particular message
has appeared on the Internet. If a message has appeared
over a certain number of times, it is categorized as
known spam. Checksums of known spam messages are utilized
by the Barracuda Spam Firewall to block spam messages.
|
| |
• |
Message
authenticity checking: Several algorithms
are utilized to verify the authenticity of a message.
Some of these are simple checks to verify that the “from
address” is authentic. Some are more complex relating
to SMTP protocol. |
| |
• |
Blacklists
and Whitelists: Domains, IP’s, and email
addresses can be blocked or whitelisted (allowed through).
These lists may be maintained on a per user basis or
on a corporate basis. |
| |
• |
Rate
controls: Utilized to stop denial of service
attacks as well as dictionary based spam attacks. These
are integrated and automatic in the Barracuda Spam Firewall.
|
| |
• |
File
type attachment blocking: You can block certain
types of files, such as vbl scripts, from entering your
company. |
User-based
and corporate-based filtering
The decision on what types of emails to block can be made
either at the end-user or at various corporate levels. You
have the flexibility to decide where you’d like the decision
to be made.
Suspect emails get quarantined
There are three main types of emails: emails that you want,
emails that you do not want (spam), and emails that are suspect.
The Barracuda Spam Firewall can tag suspect emails for delivery
into a separate folder. You can then either have the end user
or another designated person be the final judge of what to
do with these suspect emails. If after 30 days no action is
taken, the message is deleted.
Optional bulk mailboxes for
users
Barracuda Spam Firewall provides optional bulk inboxes so
that users can direct spam messages straight into these areas.
This prevents spam from cluttering up their main mail system.
These bulk email boxes can be checked periodically or ignored.
Automatic system updates
A team of engineers work out of our special operations center,
Barracuda Central, to monitor the Internet for trends in spam
and virus attacks. As they detect trends, updates are created
for the Barracuda Spam Firewall. Your Barracuda Spam Firewall
can then automatically update itself without any intervention.
There is no need to retrieve anything. No need to tune anything.
Maintaining your Barracuda Spam Firewall to deliver maximum
protection is that easy.
Logs and reports on email statistics
System administrators can view logs or generate reports at
any time from the desktop. It’s quick, easy, hassle-free administration.
No per user charges
Barracuda Spam Firewall pricing is simple. There are three
Barracuda Spam Firewall models. Each one is designed to handle
different active user and email loads. Pricing ranges from
$1199 for the smallest model to $3999 for the largest model.
There are no per user charges. Each model comes with both
spam-blocking and virus-checking capabilities.
Multiple domains & servers
A single Barracuda Spam Firewall can be used for multiple
email servers and for multiple domains.
