patented techniques including reputation checks that check not only a
message's sender IP reputation, but also the reputation of its content,
structure, links, images, attachments. Advanced techniques are also
used to analyze email content, such as adversarial Bayesian filtering,

techniques without impacting firewall processing and overall network
throughput.

each category can be rejected, tagged and delivered, sent to the user's
Junk Box, or deleted, for complete control and compliance with
corporate and regulatory requirements.

users to store junk messages. Users can receive Junk Box Summary
emails, which they may use to view (as text) and un-junk messages as
desired. IT retains control over displayed categories, scheduling, and
retention of Junk Box Summaries.
Integrated allow and block lists are built into SonicWall network
security appliances. IP addresses can be allowed or blocked at the
gateway.

lists at people, company and list levels. This feature is fully
supported by CASS and requires no additional set-up or training to use.
Integrated reporting and logging is built into SonicWall firewall.
Service status and statistics are easily displayed with one click, and
log file entries can be viewed by service name.

- Where the SonicWall Comprehensive Anti-Spam Service fitsSmaller
organizations looking to leverage their existing investment in a
SonicWall firewall can quickly ensure the delivery of only good email
to their email server with CASS. Administrators can manage CASS using a
single integrated interface on the firewall.
- Larger enterprises can layer their anti-spam protection by
placing CASS in front of a SonicWall Email Security solution to drop
more than 80% of junk email at the connection level, thus reducing
subsequent processing by downstream infrastructure.
- Distributed enterprises that receive email in multiple locations
can implement CASS on remote SonicWall firewalls to reduce spam-related
network traffic and use SonicWall Email Security to centralize email
protection services.
