Google Message Security is a 100% hosted solution that blocks spam and other threats well before they reach your enterprise. Postini is a hosted solution and requires no hardware or software to install and maintain, thus greatly reducing IT resource requirements and costs.

Postini services include message security services like spam and virus protection, inbound/outbound content filtering, and policy enforced TLS as well as message archiving packages. These can each be bundled with Google Apps (using our own email service) or can be used with third party email servers.
