Email security

摘要

This month we take a deep dive into email security. Looking at the products we have this year in contrast to last year's bunch we found that the new functionality is remarkable for its innovation and convergence with other, similar product types. Briefly, email gateways are more comprehensive than ever before and this is a big benefit to users. The players this year are a mix of old and new. The old standbys, mellowed and matured by experience, have come up with some interesting new wrinkles on aging themes.
