As cyber threats targeting email infrastructure grow more sophisticated, the need for robust email authentication protocols within government systems is more pressing than ever.

New Zealand's SEEMail framework has long provided a secure channel for inter-agency communication, but emerging global best practices—such as Domain-based Message Authentication, Reporting & Conformance (DMARC)—offer an opportunity to further fortify this trusted platform.

This presentation explores how DMARC can be leveraged to complement and enhance the SEEMail standard, providing added resilience against phishing, spoofing, and impersonation attacks.

Attendees will gain insight into:

•     The current landscape of email security within New Zealand’s public sector
•     How DMARC works and why it matters for domains used in official communication
•     Strategies for integrating DMARC into SEEMail-compliant infrastructures
•     Policy, technical, and operational considerations for full DMARC enforcement
