This paper discusses three common approaches to email encryption:
� Organization-to-organization encryption, also known as "gateway-to-gateway"
� Secure portal-based encryption, commonly referred to as organization-to-user "pull-based" encryption
� Secure attachment, referred to as organization-to-user "push-based" encryption
All of these options are easy to implement and available using on-premises solutions or through Software-as-a-Service (SaaS). This paper provides an overview of these methods and explains their distinct advantages to help you determine which approach best fits the needs of your organization.
