Protecting our Customers
Email has undoubtedly become a key tool
for communications among companies
worldwide. However, with frequent virus
attacks and the alarming rate that spam has
been filling up inboxes, email can be a
frustrating means of communicating. To
protect our customers and combat the growing
spam problem, CreoLogic provides
enterprise-class spam and virus protection
for all mail servers with top-of-the-line
Spam Firewalls from Barracuda Networks.
Protection Against Email-borne Threats
The Barracuda Spam Firewall is a powerful,
enterprise-class solution, with each
firewall appliance capable of supporting
thousands of active email users and handling
millions of messages each day. CreoLogic
currently manages 8 Barracuda Spam
Firewalls, which provide our customers with
comprehensive protection against the most
current email-borne threats that can cripple
networks if left unprotected. The Barracuda
Spam Firewall optimizes performance of our
mail servers, while utilizing the following
protections:
Anti-spam
The algorithms and methods used by the
Barracuda Spam Firewall are the most
comprehensive and most advanced in the
industry at detecting and filtering spam
resulting in the lowest rate of false
positives.
Anti-virus
By utilizing dual layer virus blocking,
decompression of archives and file type
blocking, the anti-virus engine in the
Barracuda Spam Firewall provides complete
virus protection.
Anti-phishing
The Barracuda Spam Firewall provides robust
protection against phishing schemes which
are often used to gather confidential
information about an organization or it's
individual users.
Anti-spyware (Attachments)
All attachments are scanned and any spyware
executables are detected and eliminated
immediately.
Denial of Service Protection Rate
Controls are utilized to stop denial of
service attacks as well as dictionary based
spam attacks. These rate control systems are
integrated and automatic in the Barracuda
Spam Firewall.
