Email Verification to Prevent Fraud - Seeking Sales and Implementation Partners

September 16, 2026

An independent company based in Rotterdam (Netherlands) has developed an innovative solution that helps organizations reliably verify whether a business email actually comes from the specified sender. The solution integrates seamlessly with Microsoft 365, can be deployed company-wide in just a few minutes, and requires no changes to the way Outlook is typically used. The technology offering is aimed at early commercial customers as well as Microsoft partners, Managed Service Providers (MSPs), Managed Security Service Providers (MSSPs), and cybersecurity consultancies that wish to add the solution to their portfolios and offer it to their customers. The goal is to establish long-term sales and implementation partnerships throughout Europe.

Background
Email fraud remains one of the most costly forms of white-collar crime. Attackers gain access to genuine corporate email accounts and use them to send seemingly legitimate messages requesting payments, the disclosure of confidential information, or urgent approvals. While traditional email security solutions can verify whether a message originates from an organization’s correct email system, they cannot reliably confirm whether the person accessing the mailbox is actually the legitimate sender.

How It Works and Innovation:
This Dutch solution addresses this vulnerability: Once an employee is protected, every email sent by that person carries cryptographically secured proof that it actually originated from them and was transmitted without alteration. When recipients open the message in Outlook, they immediately see a trust indicator before they respond to the email, initiate payments, or transmit sensitive data.
Key features and benefits of the solution include:
• Sender verification instead of content analysis: The solution verifies the identity of the sender rather than the writing style or content of the email, eliminating the need for AI models that require continuous retraining.
• Protection against compromised accounts: Even if attackers have gained access to a legitimate email account, unverified messages sent from that account are clearly flagged as suspicious.
• Integrity protection: Any subsequent alteration to a protected email invalidates the verification.
• Fast, low-impact deployment: Integration with Microsoft 365 typically takes less than 10 minutes; the familiar Outlook experience remains unchanged.
• Auditable Records: Every verification is logged and supports organizations during audits, investigations, or insurance-related matters.
• EU Data Protection-Compliant Deployment: The solution can be operated entirely within the European Union.
Microsoft Teams is currently being tested; further integrations for Gmail and Slack are in the planning stages.

Partners and Collaboration Models Sought
The company is seeking early commercial customers from industries with high email volumes (financial services, tax consulting, law firms, healthcare, logistics, manufacturing, public sector) as well as Microsoft Solutions Partners, MSPs, MSSPs, and cybersecurity consultancies that would like to add the solution to their portfolio and assist with implementation.
Early customers receive direct implementation support, influence over product development, and favorable terms.
The solution is already on the market and is currently being rolled out to the first commercial customers prior to a broader market launch. Commercial agreements that include technical support are preferred for this purpose.
