An independent cybersecurity review across major Connecticut credit unions 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.

Why This Matters in Connecticut
Connecticut credit unions are bound by the GLBA Safeguards Rule, FFIEC guidance, and NCUA oversight. Email authentication is critical against member phishing and wire fraud.
