The Cyber Threats Facing CPA Firms

High-Value Financial Data Under Attack

Tax returns, financial statements, bank details, and SSNs make CPA firms prime ransomware targets. One breach can impact hundreds of clients.

Email Fraud & Payment Redirection

BEC attacks exploit client trust. Attackers impersonate your firm to redirect payments or request wires—costing clients money and your credibility.

Compliance Pressure Mounting

Boards, insurers, and enterprise clients increasingly require documented controls. Weak security questionnaires can mean lost clients and higher premiums.

Busy Season Downtime = Revenue Loss

Outages during tax season mean immediate loss and missed deadlines. When you can’t file, clients leave—often permanently.

Work-From-Home Security Gaps

Hybrid work puts client data on home networks and devices. Each remote connection can become a breach point.

Client Trust Is the Product

Your reputation depends on confidentiality. A single incident can undo years of relationships.
