Deloitte ranked No.1 in Security Consulting Services Worldwide by Gartner

Press Release

16 November 2018

For the sixth consecutive year Deloitte was honoured to be named first globally for Security Consulting Services by leading research and advisory company, Gartner.

Earlier this year, Gartner released its 2018 report titled Market Share: Security Consulting Services, Worldwide, 2017, in which it named Deloitte number 1, based on revenue, in its security consulting service offering.

This recognition from Gartner validates our meticulous and strategic approach to cyber risk. With growing influence and threat posed by an increasingly digital society, cybersecurity is and should be on the agenda of all businesses,” explained Laurent Berliner, Partner and Risk Advisory Leader at Deloitte Luxembourg and EMEA Risk Advisory Leader for the Financial Services Industry. “Deloitte being positioned first in security consulting services worldwide for six years running speaks for itself. Deloitte is the most sought-after security consultant, not only to help organizations protect themselves from cyber-attacks, but to help them leverage their cyber strategy as a source of competitive advantage.”

Leaving nothing to chance

Deloitte’s breadth of capabilities in cybersecurity consulting, as well as its outreach across numerous industries and geographies, sets the firm in a steadfast position to gather insights and help clients to navigate the cyber landscape. With a view to prevent and establish appropriate responses to looming attacks, Deloitte has measures in place to manage cyber risk in a way that avoids exposure to unwanted threat.

It is important that organizations are aware of the potentially detrimental effect a lack of cybersecurity can mean for a business’ vitality. As supported by Gartner’s recognition—Deloitte’s approach represents safety, preparation, and long-term solutions,” says Stéphane Hurtaud, Partner and Cybersecurity Leader at Deloitte Luxembourg.
