A layered defense strategy enables organizations to protect their systems and applications at multiple points throughout their infrastructure. With messaging infrastructures being the most popular targets for malcode, multi-layered protection is even more critical. For this reason, Sybari offers antivirus protection on SMTP servers - before messages even reach the mail server.
