The Challenge
Development companies are prime targets for email fraud — fake invoices, payment-change requests, and spoofed messages impersonating executives or vendors. Finex Development wanted assurance that their email domain couldn’t be impersonated and that their Microsoft 365 environment was properly protected.
What We Did
- Completed a full email security audit of the company’s Microsoft 365 domain, reviewing SPF, DKIM, and DMARC authentication.
- Found the key gap: DMARC was configured but running in monitor-only mode — it was watching spoofed mail, not blocking it. We moved the domain to enforcement so impersonation attempts are rejected instead of delivered.
- Delivered a written audit report, then walked the team through it in plain language — what was already protected, what changed, and what the before-vs-after means for fake-invoice and spoofing attempts.
- Configured external email warning banners in Microsoft 365, so every message from outside the organization is clearly flagged before staff interact with it.
- Installed and configured new office Wi-Fi, with post-installation follow-up to confirm everything ran clean.
- Provide ongoing Microsoft 365 license and renewal management so subscriptions stay current without the client chasing them.
The Result
Finex Development’s domain now rejects spoofed email at enforcement level, staff see a clear warning on every external message, and their Microsoft 365 licensing is managed end to end — with a reliable office network underneath it.
