Assurance Services

Reducing risk, increasing value.

​​Helping organizations prepare to meet the assurance demands of regulations and standards.


Increasing transparency, relevance, and value of information disclosed to the market and investors around business performance is essential to enable sustainable growth. We provide specialized audit analytics and internal control services for external audit clients and other attest services related to financial reporting. We also help all clients navigate the complexities, risks, and opportunities in their “extended enterprises” by proactively managing and monitoring risks presented by third-party relationships.

Third Party Assurance

Third parties—whether traditional vendors, business partners, or inter-affiliates—often reduce time to market, lower service delivery costs, and improve customer experiences. An extended enterprise can allow a company to access specialized talent not available in-house, driving product or service innovation. The use of third parties can also help an institution better focus on its core capabilities. But along with the benefits come added risks. Outsourcing has evolved into a strategic business practice and outsourced service providers (OSPs) can have more of an impact on their clients’ internal control framework, including their financial reporting and compliance requirements.

Sustainability and conflict minerals

Sustained and high-quality performance depends, in part, on effective measurement, management, and disclosure of relevant metrics. Non-financial metrics and related information, such as those used to evaluate environmental, social, and governance (ESG) performance, can effectively complement financial metrics and reporting in helping the user of the reported information to better understand how a business is creating value.

Deloitte helps organizations comply with marketplace (e.g., investors, business partners, consumers, etc.) and regulatory demands through transparent reporting on the results of their sustainability initiatives in accordance with recognized frameworks to meet the needs of target audiences. Moreover, Deloitte practitioners bring to sustainability reporting a detailed understanding of the challenges involved in making sense of non-financial data and an understanding of the marketplace expectations for timely, reliable, and accurate reporting.
