Organizations face numerous risks that can lead to financial losses, reputational damage, and legal troubles. Effective risk management and internal controls are crucial.
Yet, internal auditors' roles are often misunderstood as mere compliance checkers, failing to recognize their actual value in assessing risks, controls, and processes.
Below, we'll explore how companies can drive performance by hiring internal auditors to mitigate risks and enhance operations.
Why Do Companies Need an Internal Auditor?
In many business cultures, laws or stock exchange regulations require listed companies to maintain internal audits. US exchanges like the NYSE and NASDAQ emphasize this process. Organizations face various risks, including compliance, data, and fraud. Some have more risks due to their global operations, while others create them through poor financial management. The nature of the trade can also be a factor. For example, a gaming publisher might need to protect proprietary game concepts, engines, and characters. Conversely, a company facing stringent foreign data privacy regulations needs expertise to navigate them or risk fines, operating restrictions, and reputational damage.

What Does an Internal Auditor Do?
Internal auditors assess risks related to enterprise controls. They possess knowledge similar to corporate controllers and analyze how the company handles billing, payroll, ERP, expenses, and reimbursement. Unlike controllers, they focus more on optimizing processes rather than handling transactional business. This involves understanding different departments such as procurement, inventory management, and IT.
Internal auditors are independent but report to the board of directors or the audit committee with critical insights. They highlight high-risk divisions, functions with complex workflows, or areas with a history of weaknesses. To identify problems, internal auditors gather necessary data by interviewing key personnel. This process saves time and ensures the most accurate information. When vulnerabilities are found, internal auditors communicate these concerns to relevant executives, allowing the organization to mitigate risks before issues escalate.
If they find a vulnerability, they can communicate these concerns to relevant executives. This freedom helps the organization mitigate the risk before the issue escalates.

Key Activities of Internal Auditors
- Risk Assessment: Evaluating potential risks in various departments and processes.
- Control Evaluation: Reviewing the effectiveness of internal controls and suggesting improvements.
- Process Optimization: Identifying inefficiencies and recommending streamlined processes.
- Compliance Monitoring: Ensuring the organization adheres to relevant laws and regulations.
- Data Analysis: Using data to identify trends, anomalies, and areas of concern.
- Reporting: Presenting findings and recommendations to the board or audit committee.
- Follow-Up: Ensuring that recommended changes are implemented and effective.
These activities highlight the strategic role internal auditors play in strengthening the organization’s operational and financial health.
Preventing Material Weaknesses
According to a PwC market overview, 55% of material weaknesses involve:
- Financial close process (timely and accurate data collection and reporting)
- Staffing issues (lack of qualified personnel or proper duty segregation)
- IT controls (weaknesses in data access, operations, or system changes)
In 2022, 62% of material weaknesses were driven by smaller companies with revenue ranging from $100–$500M. Internal auditors in such organizations should review controls in these areas to assess risks. A small team may not be enough to monitor everything, necessitating the identification of areas where controllership, CFOs, or other business leaders need more scrutiny, processing, checks, and balances.

Future of Internal Auditing
The role of the internal auditor has mostly stayed the same over the last 20 years. Today, we have more systems, automation, and data access. But that abundance also carries more complexity.
Companies still avoid using AI widely in this process yet, seeing it as a capability rather than a solution. That's because we can't just apply a standard generative model to a specific problem and expect it to work.
We need to tailor them to the solutions we want to present. There's not much access to tools that help internal auditors mitigate risk more effectively, so platforms like Safebooks AI would ensure better data governance.
Beyond Compliance: Strategic Value of Internal Auditors
Internal auditors are invaluable strategic partners, not mere compliance checkers. Their expertise in risk assessment, control evaluation, and process optimization enables organizations to mitigate risks, enhance operations, and drive performance improvements. By fostering collaborative partnerships with these professionals, business leaders gain objective insights to make informed decisions, implement effective strategies, and cultivate a culture of constant improvement.
