    Cybersecurity for Accounting Firms

    A cybersecurity and privacy program for accounting, tax, and advisory firms that handle client financial data, tax records, and sensitive business information.

    The Challenge

    Accounting firms need defensible controls for client financial data

    Accounting firms collect tax records, payroll data, financial statements, identity information, and business records that attackers can monetize quickly.

    Firms need practical safeguards, written policies, secure client portals, vendor controls, and incident response readiness that match their size and client expectations.

    • Tax, payroll, and client financial data protection
    • FTC Safeguards and privacy obligations
    • Client portal, email, and document exchange risk
    • Insurance and client security questionnaire support
