On-Premise vs Cloud vs Private Cloud Email: Which Is Best?

BFSI email security checklist

• Data residency
• Encryption
• PKI
• DLP
• SIEM integration
• Audit logging
• MFA
• Identity management
• Backup
• Disaster recovery
• Business continuity
• Vendor-risk assessment

XgenPlus specifically positions its email offering for BFSI environments with options including private cloud, sovereign cloud, on-premises, and hybrid/air-gapped deployments.

Key takeaway: BFSI organizations should ask, "What architecture provides demonstrable control over data, identity, security, resilience, and compliance?" rather than simply asking whether cloud or on-premises is better.

How Much Does Business Email Cost?

Cloud email generally offers predictable subscription-based pricing, while on-premises and private cloud require broader consideration of infrastructure, staffing, security, backup, disaster recovery, support, and implementation. Total cost of ownership is more meaningful than comparing per-user pricing alone.

• Premium security
• Storage
• Backup
• Support

On-premises

• Servers
• Storage
• Software
