User activity monitoring software makes a video recording of the entire operating screen of a PC or server. It stores the recorded video so it can be played back during inspection. This helps restrain internal fraud and enables rapid tracking when there is a problem. It is also known as a system trail audit tool.

In recent years, the market for user activity monitoring software has expanded. In 2018, the figure was estimated to be 2.14 billion yen, a 4.9% increase from the previous year, and 2.27 billion yen in 2019, a 6.1% increase from 2018 (*1). This is because companies deploying these tools have become more prevalent not only in the financial industry, which requires strong security, but also other companies and organizations. In addition, the target area they want to monitor has expanded to general employees in addition to privileged users.

User activity monitoring software is often considered part of "operation log management." Until now, tools for visualizing "when," "who," and "what" by acquiring text operation logs have been generally used as operation log management. However, such tools have the following issues, and more companies are deploying tools that record operation logs in video format.
