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), Forensic & Integrity Services (Forensics), and Technology Risk – address risk and complexity, while identifying opportunities to enhance trust in the capital markets.

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

CCaSS, FAAS, Forensics and Technology Risk 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 address data, technology and sustainability risks and opportunities, turning ambition into action. Thanks to the global experience of Assurance talent and innovative technology, they help clients navigate complex reporting standards.

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