Google Workspace, Microsoft 365, or Sovereign Email? 5 Questions a Regulated Indian Bank Should Ask First

One increasingly important technology is PKI (Public Key Infrastructure).

PKI enables:

• Digital signatures
• Identity verification
• Certificate-based authentication
• Secure encrypted communication

A trusted Certificate Authority (CA) issues digital certificates that help verify sender authenticity.

This significantly reduces risks from:

• Email spoofing
• Business Email Compromise (BEC)
• Identity impersonation
• Fraudulent communications

Example

A treasury department approving high-value transactions can digitally sign emails, allowing recipients to verify authenticity before acting.

Expert Insight

Financial institutions increasingly treat digital identity as a strategic cybersecurity control rather than an optional feature.

Key Takeaway

Email security should combine multiple layers including PKI, identity management, encryption, and user awareness.

Question 4: Can the Platform Support India's Digital Transformation Goals?

Banks increasingly seek solutions that align with national digital infrastructure, multilingual communication, regulatory expectations, and local innovation. Evaluating these capabilities early supports long-term modernization strategies.

Importance of IDN Email

India serves users across dozens of languages.

IDN (Internationalized Domain Name) Email enables organizations to use domain names in native languages.

Examples include domains using:

• Hindi
• Tamil
• Gujarati
• Bengali
• Marathi
• Punjabi

Potential benefits include:

• Better digital inclusion
• Improved customer accessibility
• Stronger local branding
• Enhanced trust
