What type of tool uses dashboards to organize data into categories and allows analysts to identify potential security incidents as they happen?

The type of tool that uses dashboards to organize data into categories and allows analysts to identify potential security incidents as they happen is known as a Security Information and Event Management (SIEM) system.

Here are the steps to answer this question:

1. Understand the question: The question is asking about a tool that uses dashboards to categorize data and helps analysts identify security incidents in real-time.

2. Identify the tool: The tool that fits this description is a Security Information and Event Management (SIEM) system.

3. Explain the tool: A SIEM system collects and aggregates log data generated throughout the organization's technology infrastructure, from host systems and applications to network and security devices such as firewalls and antivirus filters.

4. Describe its function: The SIEM software then identifies and categorizes incidents and events, as well as analyzes them. The software delivers on two main objectives, which are to provide reports on security-related incidents and events, such as successful and failed logins, malware activity and other possible malicious activities and send alerts if analysis shows that an activity runs against predetermined rulesets and thus indicates a potential security issue.
