Assurance services

Assurance teams serve the public interest by promoting trust and confidence in business and the capital markets.

EY Assurance services – comprising Audit, Climate Change and Sustainability Services (CCaSS), Financial Accounting Advisory Services (FAAS), and Forensic & Integrity Services – address risk and complexity, while identifying opportunities to enhance trust in the capital markets.

Audit teams serve the public interest by providing high-quality, analytics-driven audits with independence, integrity, objectivity and professional skepticism.

CCaSS, FAAS and Forensics teams help protect and restore enterprise and financial reputations and help support the finance function in enhancing decision-making and efficiency. Moreover, they help clients to address sustainability risks and opportunities in order to turn sustainable ambition into action. Thanks to the global experience of EY multidisciplinary talent and innovative technology they help clients to navigate the complex emerging reporting standards.

Together, EY Assurance services help protect and promote sustainable, long-term value for stakeholders.
