Microsoft has disclosed a significant security incident involving a two-week outage of security logs for several of its cloud products. The outage, caused by a bug in an internal monitoring agent, occurred between September 2 and September 19.

The affected products include Microsoft Entra, Sentinel, Defender for Cloud, and Purview. Customers may have experienced gaps in security-related logs, potentially impacting their ability to detect threats and generate security alerts.

While Microsoft insists the outage was not caused by a security breach, the incident raises concerns about the company's ability to protect sensitive customer data. The loss of logs could make it more difficult to identify unauthorized access to customer networks during the two-week period.

This incident comes a year after Microsoft faced criticism for withholding security logs from certain U.S. federal government departments. The company has since taken steps to improve its logging practices, but the latest outage highlights the ongoing challenges in maintaining robust security measures in the cloud.
