How big is Protiviti?

The firm generated approximately $1.95 billion in 2024 revenue with more than 11,000 people across Protiviti and its independent member firms.

Robert Half founded Protiviti in May 2002, staffing it substantially with professionals displaced by Arthur Andersen's collapse. The Enron audit failure had destroyed Andersen as a firm, and regulators were tightening internal control requirements through the Sarbanes-Oxley Act, signed that July. Protiviti was built for exactly that moment: demand for internal audit outsourcing was about to explode.

Sarbanes-Oxley compliance work drove the early years. Public companies needed independent help documenting and testing internal controls, and Protiviti, unconstrained by the auditor independence rules that limited accounting firms, captured a large share of that work.

Through the 2000s and 2010s the firm expanded internationally through the member firm network and broadened beyond audit into technology consulting, cybersecurity, data analytics, finance transformation, and legal advisory services. It built consulting practices in digital transformation and later in cloud, AI, and ESG advisory as client priorities shifted.

Revenue crossed $1 billion in the mid-2010s and approached $2 billion by 2024, making Protiviti one of the largest dedicated internal audit and risk consultancies. The consulting slowdown of 2023 to 2025 pressured staffing industry results generally, but Protiviti's risk and compliance focus kept demand steadier than strategy consulting peers.

Protiviti's ESG profile combines its own modest operational footprint with a growing advisory practice in ESG and sustainability consulting for clients. The firm publishes workplace and ethics disclosures, and its internal audit lineage gives its ethics program particular emphasis. Its parent Robert Half publishes consolidated ESG reporting covering Protiviti operations.

Protiviti has been named to the Fortune 100 Best Companies to Work For list for eleven consecutive years and appears repeatedly on Consulting Magazine's best firms to work for rankings. It also receives regular recognition on Forbes America's Best Management Consulting Firms lists across multiple practice areas.
