Which security tool is described as centralizing threat detection, investigation, and response to help security analysts prioritize threats?

• A. Splunk
• B. IBM QRadar
• C. AlienVault
• D. ArcSight

Answer: (C)

Centralizing threat detection, investigation, and response in one console is the hallmark of a Unified Security Management approach. AlienVault delivers this by providing USM, which combines SIEM with asset discovery, vulnerability assessment, and intrusion detection in a single platform. This unified setup lets security analysts correlate events across the environment, investigate incidents from a common case management view, and apply response actions directly within the same tool. The result is a clear, prioritized view of threats based on risk, context, and asset importance, so analysts can focus on the most significant issues first.

Splunk is primarily a data analytics and log-management platform, which can be extended for security use but doesn’t inherently present the out-of-the-box, all-in-one threat detection, investigation, and response workflow. IBM QRadar and ArcSight are strong SIEM systems with powerful correlation and analytics, but they are typically deployed as part of a broader ecosystem rather than marketed as a single unified security management solution that centralizes all three aspects.
