Our take
What our shortlists say about the one we picked.
- Fortinet FortiMail Email and Workspace Security
Best for: Fortinet customers and on-premises mail servers
It belongs here because inbound and outbound protection, DLP and encryption come in one product that runs as a gateway or through an API, which suits companies that still host their own mail servers. Multi-tenancy and a managed incident response service help if a provider runs your email security. If you use no other Fortinet products, weigh how much of its value depends on that ecosystem.
