About Our Research
All research is conducted using DMARC Busta's domain scanner, analysing publicly available DNS records. We scan for DMARC, SPF, DKIM, MTA-STS, and TLS-RPT — providing the most complete picture of email authentication posture available. No intrusion testing or email sending is performed.
Our anonymised datasets are published openly for independent verification. We believe transparency strengthens the Australian cybersecurity community.
