 == Visual event analyzer
 
-Elastic Security allows any event detected by Elastic Endpoint to be analyzed using a process-based visual analyzer. This enables security analysts to drill down into all related hosts, processes, and other events to aid in their investigations.
+{elastic-sec} allows any event detected by {elastic-endpoint} to be analyzed using a process-based visual analyzer, which shows a graphical timeline of processes that led up to the alert and the events that occurred immediately after. Viewing events in the visual event analyzer is useful to determine the origin of potentially malicious activity and other areas in your environment that may be compromised. It also enables security analysts to drill down into all related hosts, processes, and other events to aid in their investigations.

+You can only visualize events triggered by hosts configured with the {endpoint-sec} integration or any `sysmon` data from `winlogbeat`.
 
 In KQL, this translates to any event with the `agent.type` set to either:
 
 * `endpoint`
 * `winlogbeat` with `event.module` set to `sysmon`

+To find events that can be visually analyzed:
 
-1. Select *Explore* -> *Hosts* -> *Events*. A list of all your hosts' events appears at the bottom of the Hosts page.

-2. Create a KQL query that filters all `endpoint` detected events by entering either `agent.type:"endpoint" and process.entity_id : *` or  `agent.type:"winlogbeat" and event.module: "sysmon" and process.entity_id : *` into the KQL search bar, and then selecting **Update**.
+. First, view a list of events by doing one of the following:
+* Go to *Explore* -> *Hosts*, then select the *Events* tab. A list of all your hosts' events appears at the bottom of the page.
+* Go to *Detect* -> *Alerts*, then scroll down to view the Alerts table.
+. Filter events that can be visually analyzed by entering either of the following queries in the KQL search bar, then selecting *Enter*:
+** `agent.type:"endpoint" and process.entity_id :*`

+Or

+** `agent.type:"winlogbeat" and event.module: "sysmon" and process.entity_id : *`
