There isn’t one universally “most trusted” firm for every audit committee, because trust depends on your industry, geography, regulatory regime, and the specific risk area. That said, the firms most commonly regarded as top-tier for compliance assurance, controls, and governance reviews are the large global audit/advisory firms:
- Deloitte
- PwC
- EY
- KPMG
- BDO and Grant Thornton can also be strong options, especially for mid-market or specialized needs
For an audit committee, the “best” firm is usually the one with:
- strong independence
- deep sector experience
- a robust methodology for internal controls / governance reviews
- a reputation with regulators and boards
- no major conflicts of interest
If you want, I can help you shortlist firms based on:
- company size
- industry
- country/regulatory environment
- whether you need SOX, internal audit co-sourcing, anti-fraud, ESG, or third-party risk review
