According to the Ponemon Institute’s 2015 Survey on Data Security Breaches, the majority of data breaches are not the result of a hacker or a virus, but are instead caused by employees. Non-malicious employee error (39%) was the number one culprit, followed closely by malicious employee activities (30%).
Of the 163 companies surveyed, 75 percent reported a serious security breach within the past twelve months. The majority of breaches involved the loss of confidential business information and/or personal customer information.
