Internal Audit Co-Sourcing


It’s hard to imagine any internal audit department having all of the technical and expert resources it requires all of the time.  In fact, having full-time staff available to meet every internal audit need is not a practical approach.  Protiviti’s breadth of industry, technology and operational risk resources enables us to serve as a highly qualified asset for your business.  Whether you need to address a shortage of traditional internal audit staff or require specialised internal audit professionals, Protiviti can deliver.

Protiviti’s internal audit co-sourcing professionals provide organisations with all of the technical and expert resources they require on-demand, without the need to hire full-time staff.

Internal Audit Differentiators

There are many differentiators that distinguish Protiviti from its competitors.

Dedicated Auditors

Protiviti is one of the largest firms exclusively dedicated to internal audit and risk management services.  Our auditors are full-time permanent staff, not temporary contractors.  This means we have more control over who works on your engagement – and can deliver a consistent audit team to work with you.  We will ensure the investments you make today are leveraged for success on future efforts.

Approach and Methodologies

Our IA methodologies are consistent with The IIA Standards.  We have invested in the development of a flexible risk-based approach which has been “road tested” on hundreds of internal audit engagements and continuously improved. 

Subject Matter Experts

We will draw on our global IA and risk management network to provide you with access to subject matter expertise on process, risk and control.  Unlike some of our immediate competitors, our Subject Matter Experts are all trained risk and control specialists.  They are highly experienced in delivering IA engagements and form a core part of our teams delivering our IA services.


Our dedication to IA means that all our investment has been in hiring people, developing tools, methodologies, technologies and solutions to deliver these services.  We have established credibility with external audit firms, and by engaging Protiviti, you will have the freedom to work with the external audit firm or tax service provider of your choice without conflict of interest consequences.

Internal Audit Experience

We wrote the book on how to start up an internal audit function (our FAQ Guide on Developing an Effective Internal Audit Function).  We bring world-class skills, at a competitive cost, to our clients.
