An independent cybersecurity review across major California 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.

What the Results Reveal
- Scores span 74% down to 60% — only 1 of 6 organizations reach a “Good” (70%+) posture.
- 0 of 6 scored below 60%, leaving staff, students, patients, or clients exposed to phishing and impersonation.
- Weak authentication undermines the HIPAA Security Rule and increases ransomware and business email compromise risk.
