The feature that I like the best is the fingerprinting concept.
Symantec Messaging Gateway is highly effective at blocking spam and provides robust malware and antivirus defense, powered by a comprehensive database on phishing, spamming, and spoofing. Simple setup and management can be managed by one person. Stability, scalability, and advanced content filtering with extensive options enhance its appeal. However, integration with Symantec Endpoint Protection, cluster feature support, false positive issues, documentation, and exclusion handling need improvement for better threat detection and administration.
