Monitoring the internal network traffic of a company is unethical and may violate laws, regulations and company regulations. It will seriously infringe on employee privacy and destroy the trust environment. Therefore, such operations should not be carried out. However, from a theoretical perspective, if the regulations are violated, some so-called "information" that may be obtained may be: 1. **Business data transmission situation**: The frequency and content type of data interaction between different departments can be understood, such as a large number of communication records between the sales department and customers, and transaction data between the procurement department and suppliers, which may reflect the activity and focus of business development. 2. **Sensitive information transmission**: If it involves the transmission of financial statements, business secrets, strategic planning and other contents, this is obviously a violation of regulations and seriously damages the interests of the company. 3. **Employee work trends**: The situation of employees' external contacts during working hours, whether there are abnormal behaviors such as frequent communication with relevant personnel of competitors. Once again, it is emphasized that this behavior is not desirable. Maintaining the company's network security, employee privacy and good work order requires legal and compliant management and supervision mechanisms, rather than improper monitoring methods.
