With nearly 94% of email classified as junk, managing incoming messages can overwhelm administrators. SonicWall Comprehensive Anti-Spam Service (CASS) for NSA 3600 solves this by removing spam at the gateway, ensuring only legitimate email reaches your server. Designed for businesses of up to 250 users, CASS provides quick activation, powerful protection, and centralized management through your SonicWall firewall.
Quick and easy deployment
CASS takes minutes to configure and activates with a single click—no MX Record redirection required. Once enabled, it immediately blocks spam, phishing attempts, and virus-laden emails, streamlining email security without added complexity. Smaller organizations can leverage their existing firewall investment, while larger enterprises can layer CASS in front of SonicWall Email Security for enhanced protection.
Advanced protection and bandwidth efficiency
CASS delivers 98% spam-blocking effectiveness, eliminating 80% of junk at the gateway and applying advanced techniques—such as Adversarial Bayesian filtering—to analyze remaining emails. By blocking unwanted email before it enters your network, CASS conserves bandwidth, improves server performance, and ensures your users receive only trusted messages.
Robust anti-spam and anti-phishing features
Supported by the SonicWall Global Response Intelligent Defense (GRID) Network, CASS uses 14 advanced techniques, including IP reputation analysis, GRIDprint analysis, and Image Inference analysis, to identify and stop spam, phishing, and virus threats. Automatic updates every five minutes refresh IP reputations, content filters, anti-virus signatures, and spam word lists to maintain peak protection.
Enhanced control and user management
Administrators can manage spam with customizable Allow and Block lists, flexible LDAP integration (supporting multiple servers), and Junk Box summaries for users. Optional Junk Boxes securely store quarantined messages, while unique phishing protection reduces the risk of financial, personal, or sensitive data theft.
