Deloitte security consulting ranked #1 globally based on revenue by Gartner

4 July 2013

Deloitte Touche Tohmatsu Limited (DTTL) is pleased to announce that Gartner has ranked Deloitte #1 globally in security consulting based on revenue in its Market Share Analysis: Security Consulting, Worldwide, 2012 report.

Gartner defines the security consulting market as security-specific advisory services to help companies analyse and improve efficiency of business operations and technology strategies for security. Security consulting services include security-related business and IT consulting and security assurance; it excludes security audit work that results in attestation of security controls.

“We believe Deloitte’s top ranking, based on aggregate global revenue, is particularly noteworthy because clients spend their money wisely and invest in quality,” said Mike Maddison, Deloitte Head of Deloitte Security & Privacy Services for Europe, the Middle East and Africa. “We believe this report provides tangible evidence that clients value Deloitte’s security consulting services above and beyond those of other service providers.”

The security consulting service market grew 5.8 percent from 2011 to 2012, driven largely by advanced attacks, incident response and mobile security demands. Audit firms accounted for the largest overall revenue growth in the marketplace from 2011 to 2012 since they command the greatest overall portion of revenue in the market[1].

“Increasingly sophisticated cyber-attacks have become the norm,” said Maddison. “With state-sponsored cyber-terrorism and corporate espionage on the rise, multinational organisations need a consultant that can handle the scale and complexity of their cyber security needs. This is where Deloitte excels.”
