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 Iowa
Iowa law firms handle privileged client information across corporate, litigation, and regulatory matters. Weak email security increases Business Email Compromise, domain spoofing, and confidentiality risks under the Iowa Rules of Professional Conduct.
