Webinar: 'Are You Overlooking File Exfiltration by Departing Employees and Insider Threats?' for Companies with 300+ Employees

Increased Risk of Information Exfiltration with the Expansion of Microsoft 365 As the use of Microsoft 365 expands, file sharing through SharePoint, OneDrive, and Teams becomes deeply integrated into daily operations. However, file exfiltration by departing employees or insider threats, neglected external sharing links, and suspicious file operations are areas that are easily overlooked unless administrators consciously check them. Especially in companies with 300 or more employees, the number of users, files, and sharing destinations increases, making it impractical to manually track 'who handled which file, when, and how.'

Manual Tracking of Departing Employee Actions and External Sharing is Unsustainable While Microsoft 365 provides audit logs, in practice, searching, reviewing, aggregating, and reporting on these logs is time-consuming, often relying on the intuition and manual work of on-site staff or operational vendors. If external sharing, anonymous links, suspicious file operations, or signs of departing employees downloading files are not checked on a daily basis, the risk of information exfiltration may only be discovered after an incident occurs. Even if logs are retained by standard features, it is difficult for administrators to fulfill their accountability if the logs are not continuously visible as part of operations.

Visualizing Suspicious File Operations with Audit Logs This seminar will explain how to use Microsoft 365 audit logs to visualize file exfiltration by departing employees and insider threats, external sharing, and suspicious file operations. LogStare M365 is a log analysis platform that collects Microsoft 365 audit logs and provides reports and alerts to track external sharing, file access, and login status. It will be introduced from a practical perspective for companies that want to create a system for daily checks without relying on manual work for reviewing departing employee actions and external sharing.
