Cybersecurity for accounting firms

Your clients trust you with their tax, payroll, and accounts. A cyber posture aligned with your professional obligations — and the specific frauds targeting accounting firms.

01 —Your concrete challenges

Accounting and audit firms

01

You concentrate the financial flows of dozens of companies.

For an attacker, your firm is a shortcut to all your clients' treasuries. Compromising a single employee can trigger cascading frauds — and liability partly returns to the firm.

02

Wire-transfer fraud specifically targets the profession.

BEC against accountants has become a category of its own in cybercrime. Fake bank-account changes, falsified vendor transfers, fake payroll — the schemes are well-rehearsed and the amounts substantial.

03

You handle personal data at very large scale.

Pay slips, social security numbers, IBANs, health data via sick leaves — your firm is a top-tier GDPR target. A leak triggers a 72-hour notification and heavy civil liability.

04

Professional bodies are starting to require evidence.

Deontological audits now explicitly cover IT security. Without documented evidence of a structured approach, you're exposed to professional sanctions.

Why it matters

Accounting is a trust + data-concentration sector — so a very high cyber-exposure sector. Professional ethics, civil liability, and regulatory evolution converge: cybersecurity is no longer optional.

Our recommendation

Essentials is the accessible starting point for any firm under 15 staff: it covers the controls professional authorities look at first (2FA, backup, emergency plan, light GDPR). For firms past 15 staff or those handling M&A / merger files, Ally provides the continuous senior partner.
