SonicWall Comprehensive Anti-Spam Service for NSA3700

SonicWall Comprehensive Anti-Spam Service (CASS) is a subscription license that protects SonicWall NSA3700 appliances with network-level inbound email filtering. It filters incoming mail to block spam, phishing attempts, spoofed messages and malware-laden mail before those threats reach user inboxes or internal servers. The service runs natively on SonicWall firewall and email security appliances and leverages SonicWall’s cloud-based threat intelligence and IP reputation databases to identify and block threats with minimal latency, reducing server load and improving email performance. CASS enforces email hygiene policies while requiring no additional hardware or client software, and is backed by automatic threat signature updates and 24x7 support. Ideal for organizations using SonicWall appliances; please verify compatibility with your SonicWall firewall or email security appliance and confirm license terms before purchase.
