What our shortlists say about the one we picked.
Best for: Large companies needing cloud and on-premises mail
It makes the list because it offers both a cloud service and an on-premises Messaging Gateway, as a virtual or physical appliance, which suits large companies that still run their own mail servers. Browser isolation opens risky links away from the user's machine. If you plan to move mail to the cloud, ask how your policies carry over from the gateway to the cloud service.
