Business Email Is the First Door Attackers Try

A growing business strengthens Microsoft 365 or Google Workspace access before a stolen password becomes invoice fraud.

URGENT PROBLEM

What opens the conversation

Phishing and password reuse make email the easiest high-impact entry point. Standard MFA may still depend on an OTP or approval that can be socially engineered.

DISCOVERY QUESTIONS

Help the customer recognize the need.

1

Has anyone received a fake invoice or mailbox-forwarding alert?

2

Which users can approve payments or change vendor details?

3

What happens when a login comes from a new device or unusual location?

RAINBOW SECURE APPROACH

Which capabilities fit—and why

rSecureKey Human-Verified MFA

Adds color, style and interaction so plain credential text is insufficient.

Adaptive MFA

Evaluates device, location, time and behavior before selecting verification depth.

Identity monitoring

Surfaces unusual authentication activity for review.
