Accounting firms and finance departments remain top-tier targets for cyber criminals.
The reason is simple.
These teams access the systems that move money. Anyone with authorisation to accounting software, payroll platforms, invoicing tools or payment approval workflows is considered a premium target. Attackers know that compromising a finance professional’s account provides a direct path to fraudulent payments, unauthorised fund transfers and access to confidential financial information.

Business Email Compromise continues to be one of the most damaging threats in the accounting and finance sectors. Criminals impersonate directors, suppliers or trusted colleagues, pressuring staff to update bank details or approve fraudulent invoices. These attacks are highly engineered, often using information harvested from previous breaches, LinkedIn profiles or compromised email accounts. Without modern controls, even the most experienced professionals can be deceived.
A Concentrated Target for High-Value Data Theft
Accounting practices, finance teams and payroll providers handle some of the most sensitive data processed by any organisation. This includes bank details, credit card numbers, transaction histories, payroll data, tax records and corporate financial statements. In operational terms, this data enables accurate reporting and efficient financial management. In cyber-crime terms, it represents an opportunity for large-scale monetary gain.
A single breach can trigger identity theft, fraudulent transactions, account compromise and regulatory intervention. From a technical perspective, robust cyber security ensures confidentiality, integrity and availability. In simpler terms, it makes sure financial information stays protected, cannot be manipulated and remains accessible for day-to-day operations.
Because of the nature of the data involved, finance and accounting teams cannot afford even minor lapses in security controls. Trust is central to their service proposition. When financial data is compromised, clients and stakeholders lose confidence immediately, and the organisation’s reputation can deteriorate rapidly.
A Tight Regulatory Environment Demanding Precision
The accounting and finance sectors operate under strict regulatory requirements. GDPR, PCI DSS, data protection legislation and audit frameworks all require strong, demonstrable cyber security standards. These regulations are not optional. Non-compliance is treated as a failure of governance and can lead to severe penalties, legal actions and long-term reputational damage.
Robust cyber security supports compliance by providing:
• Encrypted storage for sensitive financial data
• Controlled access and user privilege management
• Detailed audit trails for all financial system activity
• Multi-factor authentication for system access
• Regular security patching and vulnerability management
• PCI DSS-aligned payment handling processes
• Policies and controls to mitigate insider threat and external intrusion
Compliance failures can create operational delays, trigger investigations and erode trust with clients, auditors and regulators.
Operational Continuity in a High-Risk, Digitally Connected Environment
Modern finance teams depend on digital systems such as cloud accounting platforms, payroll systems, client portals and banking integrations. These systems expand the attack surface and require continuous monitoring, advanced endpoint protection and secure configuration.
Hybrid working has introduced additional vulnerabilities. Staff now access financial systems from multiple environments, devices and networks. Without strong cyber security controls, a single compromised device or account can result in fraudulent transactions or unauthorised system access.
Accountants and finance professionals need a secure, controlled environment that supports efficient workflows while protecting the integrity of financial operations. Proactive cyber security is essential to reduce downtime, prevent data breaches and protect organisational liquidity.
