| The **AI Security Anomaly Detector** is a powerful and adaptable framework for identifying irregularities in access logs, user behavior, and system activity. Leveraging statistical techniques such as **Z-score** outlier detection, it serves as a dependable layer of defense in environments where real-time anomaly detection is critical. This system enables organizations to proactively respond to potential threats by flagging suspicious activity before it escalates into a security incident. | The **AI Security Anomaly Detector** is a powerful and adaptable framework for identifying irregularities in access logs, user behavior, and system activity.
