SonicWall Comprehensive Anti-Spam Service
Instant spam protection at the gateway

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.

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.
