In the dynamic landscape of corporate governance in Ireland, both internal and external auditing stand as pillars of assurance and oversight within organisations, ensuring comprehensive cross-sectoral analysis.
The two types of audits complement each other, collectively contributing to integrity, transparency, and organisational trust.
Internal audits by internal audit departments or outsourced firms focus on enhancing operational efficiency and risk identification and ensuring regulatory compliance.
On the other hand, external audits by independent auditors provide an objective assessment of financial records. It also promotes trust and confidence among stakeholders and regulatory bodies.
Understanding the alignment between internal and external audits in Ireland is essential for companies to navigate the complexities of governance, compliance, and stakeholders’ trust.
