Jizô Alert Advisor is a generative AI-based alert management solution built for Network Detection and Response (NDR) use cases. It leverages Large Language Models (LLMs) and advanced algorithms to analyze security data in real-time, identifying patterns and anomalies across alert streams. The solution is designed to assist security operators at three stages of alert handling: anticipation, prioritization, and decision-making. It reduces alert noise by filtering false positives and surfaces actionable recommendations tied to critical incidents. Jizô Alert Advisor provides a visualization interface for alerts and recommendations, with customization options to adapt to specific organizational requirements. It is offered as a component within the broader Jizô AI platform. The solution is qualified by ANSSI (French National Cybersecurity Agency) and operates with zero data transfer outside the organization, maintaining GDPR compliance. No external data sharing occurs, preserving data confidentiality.
