GWGuardian
By using a multi-layered GroupWise anti-spam and anti-virus defense with advanced POP/IMAP and SMTP security
options, GWGuardian is a complete GroupWise mail firewall that prevents unauthorised use of GWIA, blocks scan
attacks, and enforces authentication of users sending email. GWGuardian also blocks messages based on
real-time blacklists (RBL), limits the number of simultaneous connections, and rejects connections from
specified addresses or IPs.
GWGuardian is compatible with any mail server, including Novell GroupWise 5.5-6.x. The gateway is deployed
safely behind your corporate firewall through a single connection, effectively enhancing your server's
security. Furthermore, GWGuardian provides gateway intelligence that features unique user-aware
pre-authentication to prevent Denial of Service (DoS) attacks and caches authenticated users for optimal
performance. Once a message is received by GWGuardian, it connects to the mail server to verify if the user
exists: if not, the message is rejected.
Today, GroupWise administrators must contend with countless unsolicited messages. Not only is spam
irritating, but it clogs your GroupWise servers and severely impacts performance, and may allow viruses to
enter the GroupWise message store. Furthermore, spam affects daily productivity, as employees spend time
sorting through numerous messages. Many anti-spam solutions offer to help you manage spam: but spam doesn't
need to be managed, it needs to be eliminated from the mail server.
GWGuardian is the perfect solution for corporate security needs: it provides superior virus and spam
protection while maximising return on investment. Layered with intelligence, it pre-authenticates all
legitimate users before scanning for viruses and spam and provides round-the-clock virus and spam protection
that prevents spammers and hackers from exploiting your network assets. Easy deployment and administration
make GWGuardian the best line of defense for your organisation's anti-spam needs!
The Messaging Architects GWGuardian technology is the only layered solution that uses multiple filtering
technologies to identify, classify, and manage spam messages. After years of research and development,
GWGuardian introduces a software infrastructure that capitalises on the best of script, heuristic, and
statistic technologies to efficiently and reliably intercept and classify undesirable email without
interfering with the normal flow of legitimate messages.
Forbidden Attachments Scanning
A message that has been checked and accepted by the first 8-layer pre-protection mechanism is then subjected
to further scanning and processing. It is checked for Forbidden Attachments. GWGuardian features a powerful
inner file scanner that goes beyond the mere file extension and actually verifies the content of the file to
make sure it matches its extension, thus making it efficient against hidden extensions.
Whitelist / Blacklist Functionality
The email address is then checked against the user-level Whitelist/Blacklist. Email messages from a
whitelisted address bypass the scanning process and are automatically accepted, while those coming from a
blacklisted address are intercepted and quarantined, deleted, or tagged in the subject line.
Email Content Extractor
One of GWGuardian's most powerful protection layers is the Email Content Extractor. It completely strips
the body and subject of a message to prevent text, code, or subject line malformation and to provide the
subsequent layers of anti-spam defense with advanced email metrics for further analysis and a clearer
diagnosis. Any non-conforming or hidden content is thus removed and the message is sent as purified text
with added email metrics for further analysis.
Custom Sieve Scripts
If custom Sieve scripts enforcing corporate email policies have been added, the message is filtered according
to the custom rules and may thus circumvent further scanning.
Sequential Content Analyzer
Resulting from years of research and development, the new Sequential Content Analyzer (SCA) Anti-Spam
Engine allows GWGuardian to scan emails 50% faster than previous versions with an out-of-the-box catch
rate of 98.2% and a 99.99% protection against false positives. The SCA engine simultaneously analyses
message content and email metrics for flawless precision. Combined with 13 different layers of protection,
the SCA engine is robust and reliable, providing the most accurate spam detection and blocking capabilities
on the market.
GWGuardian+ AV applies the power of the award-winning McAfee virus scan engine for comprehensive virus
detection and cleaning. McAfee products are backed by AVERT (Anti-Virus Emergency Response Team), the
leading anti-virus research organisation that provides cures for major outbreaks, such as LoveLetter,
CodeRed, Nimda, Klez and BugBear.
