What is the name of the SIEM tool that assists in detecting real-time network threats?

The choice of ArcSight Enterprise Security Manager as the correct answer is based on its specific design and functionality as a Security Information and Event Management (SIEM) tool. ArcSight is well-known for its capabilities in real-time threat detection across the network. It aggregates and analyzes log and event data from various sources, allowing security professionals to identify suspicious activities and potential security breaches as they occur.

ArcSight’s powerful correlation and analysis features enable organizations to gain insights into security events, helping them respond promptly to threats before they escalate. Its ability to provide centralized visibility across complex environments makes it an effective tool in identifying patterns and anomalies related to network threats in real time.

While Loggly, Graylog, and FortiSIEM have their own strengths, they may not specifically focus on the advanced features and real-time detection capabilities that are characteristic of ArcSight. These tools serve different purposes or target audiences, which is why ArcSight stands out as the primary choice for detecting real-time network threats in this context.
