Frequently Asked Questions

1. Is on-premises email more secure than cloud email?

Not automatically. Security depends on implementation, patching, monitoring, identity controls, encryption, backup, and incident response.

2. Is a private cloud the same as on-premises?

No. A private cloud is dedicated to one organization and can exist either on-premises or off-premises.

3. Which email solution is best for small businesses?

Cloud email is generally the easiest starting point because it reduces infrastructure management and enables rapid deployment.
