GET - Affected hosts by threat id

Overview

This endpoint retrieves a paginated list of all endpoints where a specific threat has been detected. Target a threat by its threat_id in the path. The response contains an array of endpoint objects, which can be sorted and filtered by time. Use this API to determine the scope of an incident. After a threat is identified, call this endpoint to get the full list of affected endpoints. This list is the basis for scoping your investigation and for creating a target list for remediation actions.

Authentication

Authentication type: Bearer Token, API Key.

You can create a token using client credentials obtained through the developer portal. The API Key (x-api-key) is provided in your onboarding email or on the API Access Management page.

Request

Request headers

Authorization: Bearer <your_bearer_token>
Content-Type: application/vnd.api+json
x-api-key: <your_api_key>
Accept-Encoding: gzip

Authorization: This header is used to authenticate your request. You need to replace <your_bearer_token> with the actual token you generate.
Content-Type: This header tells the server that the request body format is json:api. Even though this specific call has no request body, the API requires this header.
x-api-key: This is a custom header required by the Trellix API for authentication. You'll need to replace <your_api_key> with the key from your onboarding email or the API Access Management page.
Accept-Encoding: This is an optional header you can include to tell the server you can accept a compressed response (using gzip), which can make the data transfer faster.
