Configuring SentinelOne Connectors
This connector allows Stellar Cyber to collect data from external sources and add the records to the data lake.
SentinelOne integration with Stellar Cyber provides advanced threat detection and response capabilities, combining AI-powered endpoint protection with real-time threat intelligence and automated response workflows to improve incident response and threat mitigation.
A SentinelOne connector allows you to collect logs, discover assets, and see vulnerabilities. If you enable Respond options on this connector, with the correct type of user account, you can perform the following endpoint response actions:
The following error from Sentinel One, 503 Service Temporarily Unavailable, is treated by Stellar Cyber as the following error, 429 Too Many Requests, and is not shown on the DP connector list. This will be addressed in a later release.
This connector is improved to use less memory. Under certain scenarios if there is an error reaching the third-party API, some duplicate messages may be sent.

Third Party Native Alert Integration Details
SentinelOne's threat dataset includes a variety of fields that enable Stellar Cyber to map the native SentinelOne alerts to the Stellar Cyber Alert index. For example, threatInfo.classification
describes the event (such as Trojan). That and other fields in the threatInfo
record support direct mapping of SentinelOne's MITRE | ATT&CK Tactic and Technique fields to Stellar Cyber's XDR Kill Chain. Of the assorted collected data types noted above, only the Threats (msg_class: sentinelone_threat_detection
) are directly mapped to the Alert index.
For details, see Integration of Third Party Native Alerts.
Required Credentials
-
Host URL and API Key (token).
-
To Collect, the SentinelONE User Account can have either the Viewer or Admin role. To Respond, the user Role must be Admin.

Adding a SentinelOne Connector
To add a SentinelOne connector:
- Obtain SentinelOne credentials
- Add the connector in Stellar Cyber
- Test the connector
- Verify ingestion
You can also configure SentinelOne to send logs to the Stellar Cyber parser. However, the connector allows you to assign a tenant, while the parser does not.
Obtaining SentinelOne Credentials
As part of this procedure, you specify the credentials of an account on the SentinelOne server that will be used to retrieve data. This account must have read/view permissions or better on the SentinelOne server. To perform response actions, the account must have an administrative role.
-
Log into your SentinelOne Management Console as an administrative user (for example: https://usea1-partners.sentinelone.net/login).
-
From the Management Console navigation pane, select Settings.
-
Navigate to Site Info.
-
Make sure that Licenses is Complete for the site and that Add-ons is STAR.
Some content types require an upgraded subscription (STAR) as well as permissions, otherwise the connector will not produce expected results.
-
In the tab for Users, choose Roles.
-
For the role, set the following permissions for certain content types:
-
To support the Deep Visibility content type, choose Deep Visibility View.
-
To support the Threats content type, choose Threats View.
-
To support the Rogues content type, choose Rogues View.
If these features are Not allowed (greyed out), contact SentinelOne.
-
-
Click Save.
-
Choose the Users tab and select the option to add a New User for the account you will use with the Stellar Cyber connector.
-
In the User Details, enter the information for the new user.
-
Make sure to assign a role to the account, either Viewer or Admin.
-
Log out of the SentinelOne Management Console and then log back in with the username you created. You are prompted to create a password for that user. Create the password and complete the login.
-
When logged into the SentinelOne online console as an administrative user, you need to generate an API token for the connector configuration. The token can be generated from a console user or from a service user.
The following steps are to generate the API token from a console user:
-
Click the username from the top right of the console and select My User.
-
In the dialog that displays, click the link to Generate an API Token.
-
This displays the token with a warning to copy it. If you forget the token, you will need to regenerate it. Download it now or Copy it and save it to a file for later use in the connector you configure in Stellar Cyber.
-
Exit the console and proceed to the next section.
The following steps are to generate the API token from a service user:
-
Click the USERS tab and choose Service Users. Then select Create New Service User from the Actions menu.
-
Enter the Name of the New Service User and choose an Expiration Date.Then click Next.
-
You can set the Scope of Access for the Account or the Site.
-
To set the Scope of Access for the Account, select Account. Choose Admin or Viewer from the drop-down menu for the role. Choose Admin for respond actions.
-
To set the Scope of Access for the Site, select Site. Choose Admin or Viewer from the drop-down menu for the role. Choose Admin for respond actions.
-
Click Create User.
-
Copy the API Token.
Store the API key in a safe location. It cannot be retrieved later although it can be regenerated.
-
Click Close.
-
Adding the Connector in Stellar Cyber
To add a SentinelOne connector in Stellar Cyber:
-
Log in to Stellar Cyber.
-
Click System | Integration | Connectors. The Connector Overview appears.
-
Click Create. The General tab of the Add Connector screen appears. The information on this tab cannot be changed after you add the connector.
-
Choose Endpoint Security from the Category drop-down.
-
Choose SentinelOne from the Type drop-down.
-
Enable the Function for Collect and/or Respond.
-
Enter a Name.
This field does not accept multibyte characters.
-
Choose a Tenant Name. The Interflow records created by this connector include this tenant name.
-
Choose the device on which to run the connector.
-
(Optional) When the Function is Collect, you can create Log Filters. For information, see Managing Log Filters.
-
Click Next. The Configuration tab appears.
The asterisk (*) indicates a required field.
-
Enter the Host URL. This is the address of your SentinelOne server.
For release versions prior to v4.3.4, ensure the URL does not include a trailing "/" symbol.
-
Enter the API Key (token) you created above.
In earlier releases, Stellar Cyber supported use of a Username / Password combination. However, SentinelOne now enforces use of 2FA, which necessitates use of a token with API communications.
-
Enter the Interval (min). This is how often the logs are collected.
-
Choose the Content Type. The following logs are supported:
-
Host (Agents)
-
Threat
-
Vulnerabilities
-
The following logs are supported for v4.3.5, and later.
These content types require an upgraded subscription (STAR) as well as permissions. See Obtain SentinelOne Credentials for details.
-
Alerts
-
Deep Visibility
-
Events (Threat Events)
-
Rogues
-
Threat Notes
-
-
-
Click Next. The final confirmation tab appears.
-
Click Submit.
To pull data, a connector must be added to a Data Analyzer profile if it is running on the Data Processor.
The new connector is immediately active.
Testing the Connector
When you add (or edit) a connector, we recommend that you run a test to validate the connectivity parameters you entered. (The test validates only the authentication / connectivity; it does not validate data flow).
For connectors running on a sensor, Stellar Cyber recommends that you allow 30-60 seconds for new or modified configuration details to be propagated to the sensor before performing a test.
-
Click System | Integrations | Connectors. The Connector Overview appears.
-
Locate the connector that you added, or modified, or that you want to test.
-
Click Test at the right side of that row. The test runs immediately.
Note that you may run only one test at a time.
Stellar Cyber conducts a basic connectivity test for the connector and reports a success or failure result. A successful test indicates that you entered all of the connector information correctly.
To aid troubleshooting your connector, the dialog remains open until you explicitly close it by using the X button. If the test fails, you can select the button from the same row to review and correct issues.
The connector status is updated every five (5) minutes. A successful test clears the connector status, but if issues persist, the status reverts to failed after a minute.
Repeat the test as needed.
Verifying Ingestion
To verify ingestion:
-
Click Investigate | Threat Hunting. The Interflow Search tab appears.
-
Set the Indices to match the type of content you collected:
-
For Threat data, change the Indices to Syslog or Alerts.
-
For Host data, change the Indices to Assets. Note that hosts discovered through this connector show SentinelOne as a data source.
-
For Vulnerabilities, change the Indices to Scans.
-
