An independent cybersecurity review across major South Dakota hospitals and healthcare systems reveals a wide range of results. Many organizations handle sensitive communications daily, yet show significant gaps in email authentication and transport security.
Using data from audit.emailmenow.com, we evaluated each domain across email, website, and network security — including SPF, DKIM, DMARC, MTA-STS/TLS, and security headers.

Overall compliance scores from audit.emailmenow.com, measured June 5, 2026. Re-run any domain at the link to verify.
| Rank | Organization | Domain | Overall Score | Performance Level |
|---|---|---|---|---|

What the Results Reveal
- Scores span 73% down to 38% — 3 of 6 reach a Good (70%+) posture.
- 2 of 6 scored below 60%, leaving stakeholders exposed to phishing and impersonation.
- Weak authentication undermines compliance expectations and increases BEC and wire-fraud risk.
Why This Matters in South Dakota
South Dakota hospital systems must meet the HIPAA Security Rule and document risk analyses. Email and web exposures remain among the most common OCR enforcement drivers.
