 In Cloud SIEM, *entities* are fundamental to the insight generation process. When a Cloud SIEM rule fires, it generates a signal for each “on-entity” attribute configured for the rule. Cloud SIEM correlates signals by entity to create insights. This process is described in the [Insight Generation Process](/docs/cse/get-started-with-cloud-siem/insight-generation-process/) topic.

 When you create a rule, in the signal configuration section, the rules editor prompts you to select an “on-entity” attribute from a list of all of the Cloud SIEM schema attributes that hold entities. What if you want to correlate signals by something other than an item that is one of Cloud SIEM standard entity types? That’s what custom entity types are for.

 ## About entities
 
-In Cloud SIEM, an entity is a unique actor that a signal fired upon. Cloud SIEM has a number of [built-in entity types](https://github.com/SumoLogic/cloud-siem-content-catalog/blob/master/schema/entity_fields.md):
-
-* Command
-* Deployment
-* Domain
-* Email
-* File
-* Hash
-* Hostname
-* IP Address
-* MAC Address
-* Pod
-* Process
-* Replica Set
-* Resource
-* URL
-* User Agent
-* Username

-You can create custom entity types as well. For more information, see [Create a Custom Entity Type](/docs/cse/records-signals-entities-insights/create-custom-entity-type/).
+In Cloud SIEM, an entity is a unique actor that a signal fired upon, for example, IP address, hostname, or username.
 
 When a signal is fired, if an entity doesn’t already exist in Cloud SIEM for the item that the signal fired on, Cloud SIEM creates an entity for it. For more information about entities and signal and insight generation, see [Insight Generation Process](/docs/cse/get-started-with-cloud-siem/insight-generation-process).

 :::note
 Entity names have a limit of 512 characters. If an entity's name value is 512 characters or longer, the system discards the log, and as a result, no signal is generated.
