In this Email Security Gateway installation, all spam and virus filtering occurs in Email Security Gateway using the product's collection of antispam and antivirus engines and tools. Data Security data loss prevention (DLP) policies filter mail for acceptable usage and sensitive company data. See the
TRITON - Email Security Help for information about Email Security filtering tools.
This Email Security Gateway Anywhere environment includes the Email Security hybrid service "in the cloud" filtering. Register for the hybrid service in the Email Security Gateway management interface (
Settings > General > Hybrid Configuration). See the
TRITON - Email Security Help for details.
The hybrid service may also share spam and virus detection information by writing extended headers in the mail it sends to Email Security Gateway. The additional header information includes a spam/virus detection "score," which Email Security then uses to determine message disposition.
