An independent cybersecurity review across major Wisconsin accounting firms 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 30% — 3 of 8 reach a Good (70%+) posture.
  • 3 of 8 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 Wisconsin

Wisconsin accounting firms hold sensitive taxpayer data. The IRS (Publication 4557) requires a written information security plan, and the FTC Safeguards Rule backs it with civil penalties.
