As a society, we have greatly profited from the digitisation of our processes, the rise of the Internet and the Internet of Things (IoT). As companies, we are able to connect systems and data so that we can work efficiently and provide customers with the best service at the lowest cost. These benefits also bring a great amount of dependency on these systems and have subsequently opened a Pandora's Box of very real and ever-increasing cyber- and technology-related exposures. Many cyber incidents are the result of actions taken by someone within the organisation. And a special category that is getting increasing attention is the disgruntled employee. In recent years, we have seen examples of employees facilitating sabotage and fraud for the benefit of a new employer or to satiate their need for recognition. Whatever the motivation, insiders are perfectly placed to wreak considerable damage on the organisation, either through sabotage or data theft, as Sjaak Schouteren of JLT Specialty explains.
