Email and Spam Filtering
Spam filtering can block unwanted email from entering users’s inbox.
Studies have estimated that 50-60% of today’s email is spam and spam filters can dramatically reduce the impact that email traffic has on your network.
Most importantly, it can prevent users from unknowingly open a seemingly legitimate email and compromising your security.

Superior inbound email protection. SES delivers its industry-leading spam, phishing and virus-laden e-mail protection by combining Advanced Reputation Management (ARM) with Advanced Content Management (ACM).
ARM logs and blocks junk emails coming from outside email servers before they can enter your network and degrade performance. ARM applies Sender IP Reputation, SonicWALL’s unique GRIDprint technology and Bounce Address Tag Validation (BATV) for NDR (back-scatter) messages. ARM also protects against Directory Harvest Attack (DHA) and Denial of Service (DoS) attacks.
ACM further analyzes the email, using comprehensive layered techniques including Adversarial Bayesian filtering, image analysis, gibberish detection, corporate or user allow/block lists and more. ACM scans content in email components (body, subject, attachments, etc.) to assure compliance with corporate policy, and can block or re-route non-compliant emails.
Complete outbound email protection.
In addition to full inbound protection, SES applies Outbound Threat Management (OTM) and Compliance Defense Management (CDM) to provide complete outbound protection on the same system.
OTM combines anti-virus and time-zero protection services to scan all outbound email to ensure it is good and virus-free. OTM also identifies and blocks zombie-generated email and alerts the administrator.
CDM combines SonicWALL’s built-in policy engine and compliance services to identify, route and report on compliance-related information entering or leaving the organization via email. The extensive CDM tool set includes compliance dictionaries, record-id (pattern) matching, compliance reports, approval boxes with alerts, archiving and encryption.
Easy-to-install, easy-to-manage, easy-to-own.
SES is easy to install using default configurations for basic needs, but is also flexible enough to support tailored customization. Using the 5-step Quick Configuration option, SES can be installed and operational in under an hour.
SES eases management by automating mundane tasks such as signature updates, status reporting, and LDAP synchronization. SonicWALL's industry-leading end-user tools improve productivity while retaining full IT control.
SES is easy to own because it is engineered to deliver greater value. SES is backed by the SonicWALL GRID Network' global real-time threat updates; the SonicWALL Research Lab's relentless vigilance against emerging spam, phish and viruses; and SonicWALL Engineering's continuous product improvements to meet the changing needs of your organization.
