Increasingly, organizations of all sizes are awakening to the perils posed by cyber attacks. For years, many groups tried to ignore the problem, dismissing cybersecurity as a concern only for the biggest, most high-profile entities, be they government or corporate. These days, more groups are coming to understand how ruinous such intrusions could be. This has led to a dramatic rise in the demand for cybersecurity executives and search firms in this sector continuing to grow. Recruitment firm Harvey Nash Group recently appointed Jim Tiller as global chief information security officer to support its growth and establish a new virtual CISO practice.
