Independent assurance & reviews

Confident decision-making fuelled by reliable information and processes.

Reliable and credible information is high on stakeholders’ agendas, particularly in today’s world where data is widely available. Independent assurance provides confidence in the subject matter of that assurance engagement.

In addition to statutory audits, we perform a wide range of assurance engagements to help you meet regulatory requirements, ensure transparency and enhance stakeholder engagement.

Our approach

We perform independent assurance engagements which offer expert opinions on different areas of business performance and information. These opinions meet the requirements of international professional standards and enhance credibility and respond to the needs of stakeholders for greater transparency.

Mazars can perform a wide range of assurance reviews, on diverse areas including:

  •  Internal controls, such as ISAE3402, SOC1 or SOC2, etc;
  •  Human rights;
  •  Corporate culture;
  •  Anti-bribery and corruption;
  •  Diversity and inclusion;
  • Data privacy or security;
  • Fraud;
  • Carbon emissions;
  • Non-financial disclosures included in corporate reports in line with local regulatory requirements.

 These enable organisations to:

  • Meet regulatory requirements;
  • Enhance stakeholder engagement through increased transparency, and gain competitive advantage with customers, investors, regulators and other stakeholders;
  • Improve external rating scores on ESG and other areas;
  • Match transparency expectations set by competition;
  • Enhance internal decision-making processes with more accurate and reliable information.

We can work with you to help you identify what level of assurance fits your needs, the expectations of your stakeholders, and the requirements of relevant reporting frameworks.
