US regional accounting firm accepts an insurance broker cyber referral to close a renewal-cycle gap.

An American regional accounting firm accepted a cyber referral from its commercial insurance broker to close a specific renewal-cycle exposure the broker's cyber underwriter had flagged. The engagement produced the substantiating documentation the underwriter required to bind the renewal.

Engagement origin

The firm operates a regional accounting practice with approximately fifty staff across two American states, serving corporate clients across multiple industries. The firm's commercial insurance broker had submitted the firm's cyber renewal intake, and the underwriter had flagged the responses on multi-factor authentication and business email authentication as insufficient for the requested limit. The broker introduced LeakTrace as the pre-binding audit path.

Discovery scope

LeakTrace conducted a seventy-two-hour external attack surface audit against the firm's registered domain, staff email patterns, public directory records associated with the firm's American Institute of Certified Public Accountants membership, and vendor mapping. The engagement was scoped to substantiate the flagged intake responses and identify any additional exposure conditions.

Findings summary

• Staff credential exposure. Multiple staff email addresses appeared in monitored breach databases. Reuse patterns extended into the firm's tax preparation platform and client portal.
• Multi-factor authentication verification. The firm had multi-factor authentication enforced across client-facing platforms, contrary to the intake response's ambiguity. Backup authentication methods for two staff reduced the strength below the underwriter's baseline.
• Business email authentication. Sender Policy Framework and Domain-based Message Authentication configuration met current baselines but required minor adjustment.
• Client portal exposure. The firm's client portal was reachable without bot mitigation. The vendor had documented guidance the firm had not applied.

Firm actions

The firm executed remediation. Credentials were rotated and backup authentication methods were restricted to hardware tokens. Business email authentication was revised. Client portal vendor guidance was applied. Intake responses were corrected in writing to reflect the actual posture.

Outcome

The underwriter bound the renewal at the requested limit with no premium loading applied. The audit was accepted as substituted evidence for the flagged intake responses. The firm retained LeakTrace for annual pre-renewal baseline refresh through the broker relationship.
