Tommy Helsby, Kroll's co-chairman, investigations and disputes, said, “It’s becoming an increasingly risky world, with the largest ever proportion of companies reporting fraud and similarly high levels of cyber and security breaches.
“The impact of such incidents is significant, with punitive effects on company revenues, business continuity, corporate reputation, customer satisfaction, and employee morale.
“With fraud, cyber, and security incidents becoming the new normal for companies all over the world, it’s clear that organisations need to have systemic processes in place to prevent, detect, and respond to these risks if they are to avoid reputational and financial damage.”
Kroll interviewed 545 senior executives worldwide across different industries and countries between July and August 2016.
