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

virus. Messages in 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.

User Junk Box option
enables quick
setup of Junk Boxes for all 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. IT

administrators can add granular control

with Allow and Block 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. Service status shows

availability of CASS, Junk Boxes and the

downstream email server.

LDAP integration
enables robust, easy
and secure user management, as well

as additional flexibility through LDAP

integration support.

Supports downstream email security

systems
such as corporate governance
or compliance policies, per-user policies

and preferences, advanced reporting and

more, as needed.

Where the SonicWall Comprehensive

Anti-Spam Service fits

Smaller 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.

How the SonicWall Comprehensive Anti-Spam Service works

1
SMTP traffic arrives at the SonicWall
firewall.

2
The Comprehensive Anti-Spam Service
checks the reputation of the sending

IP server in real time. The SonicWall

Capture Threat Network receives real-

time inputs from over 4 million endpoints

worldwide to determine the reputation

of servers that are sending email. Up to

80% of junk email can be dropped at the

connection level, thus reducing overall

processing by the firewall. The remaining

email is processed using the cloud-based

SonicWall Capture Threat Network which

applies SonicWall’s proven spam detection

techniques.

3
Good email is delivered to the email
server.

4
Optionally, junk email can be delivered to
SonicWall Junk Boxes on the email server

and Junk Box Summaries for each user can

be delivered as emails to each user.
