Features ⫘

With the help of Entity Graph, you can:

• Visualize how entities are connected. The visual graph displays entity relationships, allowing you to easily see connections across different data sources. This provides a holistic view of how entities are involved in an attack.
• Select an entity node to gain additional insights about the entity, such as its properties, related alerts, related entities, and threat intelligence, if available.
• Select an edge to understand the alerts and events that are part of that relationship.

Explore Entity Graph ⫘

Entity Graph is divided into two main sections: the interactive graph on the left panel and the tabs on the right.
