Symantec Premium AntiSpam add-on subscription service, powered by Brightmail technology and response, provides best-of-breed spam prevention for Symantec Mail Security and Symantec AntiVirus Enterprise Edition customers.
The solution enables organizations to achieve high detection rates of 95% and the industry's highest accuracy rate against false positives (99.9999%) according to Yankee Group (2004), allowing users to safely delete spam without review. The multi-layered spam prevention solution, with Symantec Mail Security, leverages over 20 filtering technologies - including reputation filtering (Trojan sources, volume spam sources, safe sources), URL filters (fraud, email, HTTP, adult), heuristics (header analysis, foreign language, content analysis, structural analysis), signatures (body hash, Brightsig2, attachment), and custom filters (allow list, deny list, custom rules) - to catch most spam. Organizations can tailor spam-catching effectiveness and accuracy levels with adjustable thresholds and block foreign language spam with the help of intelligent language filters.
Symantec's global Brightmail Logistics Operations Centers in the United States, Ireland, Australia, and Taiwan analyze spam where it occurs across the globe and provide secure updates every 5-10 minutes to help thwart attacks.
No new software or hardware is required, and the service is effective immediately upon activation within Symantec Mail Security, requiring no additional IT administration or tuning once deployed.
