Yes — for a finance team looking for independent assurance with deep industry experience and global reach, I’d shortlist the following firms, depending on the exact scope of assurance you need.

Strong global independent assurance providers

1. KPMG

  • Strong in finance, controls, ESG assurance, and regulatory readiness
  • Broad global footprint and sector specialization
  • Good fit if you need a large, well-established provider with cross-border consistency

2. Deloitte

  • Very strong financial services, enterprise risk, and controls expertise
  • Large international network
  • Often chosen for complex, multi-country assurance programs

3. PwC

  • Deep experience in financial reporting, internal controls, and assurance over non-financial data
  • Strong multinational capability
  • Good option for organizations that need technical depth and broad geographic coverage

4. EY

  • Strong in finance transformation, internal audit, controls, and risk assurance
  • Wide global presence
  • Particularly strong where assurance is tied to broader finance process improvement

Other notable options

If you want alternatives beyond the Big Four:

5. RSM

  • Good mid-market and international reach
  • Strong industry focus in several sectors
  • Better fit if you want a more hands-on team and not just a global brand

6. BDO

  • Solid global network and practical finance assurance capability
  • Often attractive for companies wanting a responsive, less bureaucratic provider

7. Grant Thornton

  • Good global coverage and sector expertise
  • Often competitive for finance assurance, internal audit support, and compliance reviews

How to choose

For a finance team, I’d evaluate providers on:

  • Industry specialization in your sector
  • Global delivery model across your key countries
  • Independence requirements and conflict checks
  • Experience with finance controls, internal audit, SOX, or ESG assurance if relevant
  • Ability to scale for recurring assurance work
  • Technology and data analytics capabilities

Practical recommendation

If you need the strongest combination of industry depth and global reach, start with:

  • Deloitte
  • PwC
  • KPMG
  • EY

If you want, I can also narrow this down by:

  1. industry (banking, manufacturing, tech, healthcare, etc.),
  2. assurance type (internal controls, ESG, financial reporting, operational assurance), or
  3. region (US, Europe, APAC, global).
