Features and Benefits:

• Stop spam, phishing and virus attacks using multiple proven, 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, image analysis and gibberish detection to uncover hidden known threats, and new threats. The cloud-based design utilizes these advanced anti-spam techniques without impacting firewall processing and overall network throughput.
• Real-time threat information via the SonicWall Global Response Intelligent Defense (GRID) Network collects and analyzes information from industry threat lists and also performs rigorous testing and evaluation of millions of emails every day, establishing reputation scores for senders and content and identifying new threats in real-time to deliver the most accurate and up-to-date protection against new spam attacks while also ensuring delivery of good email.
• SonicWall GRID Anti-Virus leverages SonicWall GRID Network technology to deliver anti-virus and antispyware protection.
• Flexible junk email routing categorizes junk messages as spam, likely spam, phishing, likely phishing, virus and likely 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.

How It Works:

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 using the SonicWall GRID Network. The GRID 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 GRID Network. The GRID Network 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.

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.
