Innovation starts with an idea.

Mistakes are made every day. But in cybersecurity, small mistakes are often overlooked. According to a study by The Information Systems Audit and Control Association, human error is one of the largest contributing factors to cyber and system incidents. It takes years to build an organizational reputation and only a few minutes of a cybersecurity incident to tear it down.

Understanding which users present the highest likelihood of causing a data breach in the coming days, weeks, or months is paramount to know where to focus your IT Security attention.  SixEngines.
