Export scan data generated by Endor Labs to an AWS S3 storage bucket. This enables long-term data retention for compliance requirements, integration with security information and event management (SIEM) systems, and custom analytics workflows. The export framework supports exporting findings in JSON or SARIF format, allowing flexible integration with your existing toolchain. Amazon S3 is an object storage service provided by Amazon Web Services (AWS). It offers high durability, availability, and scalability for storing and retrieving any amount of data. S3 integrates with other AWS services and third-party tools, making it ideal for data archival, backup, and analytics workflows.

​
Prerequisites

Ensure that you meet the following prerequisites before exporting data to S3:

​
Create an S3 bucket

An S3 bucket is a container for storing objects in Amazon S3. Each bucket has a globally unique name and is created in a specific AWS region. You can create a general purpose S3 bucket or reuse an existing bucket to store the exported data. Disable access control lists (ACLs) on the bucket to ensure that the access is managed through IAM policies and bucket policies, preventing unintended public access. Refer to Creating a bucket for detailed instructions on creating an S3 bucket. S3 buckets

​
Configure bucket lifecycle

You can configure S3 lifecycle rules to automatically delete exported data after a specified retention period. Exported objects do not expire unless you configure lifecycle rules.
  1. In the AWS management console, navigate to Amazon S3 > Buckets.
  2. Select your bucket.
  3. Select Management and click Create lifecycle rule.
  4. Enter a Lifecycle rule name, for example, endor-exports-expiry.
  5. Under Filter type, select Limit the scope of this rule using one or more filters and enter endor/ as the prefix to apply the rule only to exported data.
  6. Under Lifecycle rule actions, select Expire current versions of objects.
  7. Under Expire current versions of objects, enter the number of days after which objects should be deleted.
  8. Review the rule and click Create rule.

​
Configure access for Endor Labs

Endor Labs uses OIDC federation to assume an IAM role in your AWS account to access the S3 bucket. To allow Endor Labs to write to the bucket, configure OIDC and IAM using one of the following methods:
  • Use the CFT template to create the OIDC identity provider, IAM role, and S3 write policy.
  • Use the AWS Management console to create access by adding the OIDC identity provider and IAM role.

​
Create AWS resources using a CFT template

Use an AWS CloudFormation Template (CFT) to create the IAM role and S3 PutObject policy for the S3 exporter. The template can create a new OIDC identity provider for Endor Labs or reuse an existing provider in your account. The following table lists the parameters you can set when deploying the CFT template.
  1. Create a .cft file with the following template. You can use the following template and set the parameters according to your OIDC audience, tenant namespace, bucket name, role name, and optionally an existing OIDC provider ARN. 
    AWSTemplateFormatVersion: "2010-09-09"
Description: >
  Endor Labs S3 Exporter - creates IAM OIDC provider (optional), role, and minimal S3 PutObject policy.

      "Action": [
        "s3:PutObject"
      ],
      "Resource": "arn:aws:s3:::<your-bucket-name>/*"
    }
  ]
}
    Replace <your-bucket-name> with the name of your S3 bucket.
  5. Click Next.
  6. Under Review and create, enter a Policy name. For example, EndorLabsS3ExportPolicy.
  7. Review the Permissions defined in this policy section to confirm that the expected Amazon S3 write actions are included.
  8. Optionally, add a description and tags to your policy.
  9. Click Create policy.

​
Create an S3 exporter

Create an S3 exporter using the Endor Labs API to configure the export destination and data types. The following table lists the configuration options required to create the exporter. Run the following command to create an S3 exporter. 
endorctl api create \
  --namespace=<namespace> \
  --resource=Exporter \
  --data '{
    "meta": {
      "name": "<exporter-name>"
    },
    "propagate": true,
    "spec": {
      "exporter_type": "EXPORTER_TYPE_S3",
      "s3_config": {
        "bucket_name": "<your-bucket-name>",
        "region": "<aws-region>",
        "assume_role_arn": "<iam-role-arn>",
        "allowed_audience": "<oidc-audience>"
      },
      "message_type_configs": [
        {
          "message_type": "MESSAGE_TYPE_FINDING",
          "message_export_format": "MESSAGE_EXPORT_FORMAT_JSON"
        }
      ]
    }
  }'
For example, to create an S3 exporter named s3-findings-exporter in the namespace doe.deer that exports findings in JSON format, run the following command. 
endorctl api create \
  --namespace=doe.deer \
  --resource=Exporter \
  --data '{
    "meta": {
      "name": "s3-findings-exporter"
    },
    "propagate": true,
    "spec": {
      "exporter_type": "EXPORTER_TYPE_S3",
      "s3_config": {
        "bucket_name": "my-endorlabs-exports",
        "region": "us-west-2",
        "assume_role_arn": "arn:aws:iam::123456789012:role/EndorLabsS3ExportRole",
        "allowed_audience": "s3-exporter"
      },
      "message_type_configs": [
        {
          "message_type": "MESSAGE_TYPE_FINDING",
          "message_export_format": "MESSAGE_EXPORT_FORMAT_JSON"
        }
      ]
    }
  }'

​
Configure scan profile to use the S3 exporter

After creating the exporter, associate it with your scan profile. You can also set the scan profile as the default for your namespace so all projects use it automatically. See Scan profiles for more information.

​
Configure the scan profile

  1. Select Settings from the left sidebar.
  2. Select Scan Profiles.
  3. Select the scan profile you want to configure and click Edit Scan Profile.
  4. Select your exporter under Exporters and click Save Scan Profile.

​
Configure the project to use the scan profile

Associate your project with a scan profile to enable automatic export of scan data.
  1. Select Projects from the left sidebar and select the project you want to configure.
  2. Select Settings and select the scan profile you want to use under Scan Profile.

​
Scan projects to export data

After configuration, subsequent scans automatically export data to your S3 bucket. You can trigger a scan immediately using the rescan feature. See Rescan projects for more information. To validate that the S3 exporter ran successfully for a scan:
  1. Select Projects from the left sidebar and select the project associated with your exporter.
  2. Select Scan History and select a record to view its information.
  3. Select Logs to view the scan log and set the log level to All The following message confirms that the S3 export is successful. INFO: Successfully completed S3 export

​
Exported file structure

Endor Labs exports data to S3 using a hierarchical folder structure: 
endor/
└── <exporter-uuid>-<exporter-name>/
    └── <namespace>/
        └── <project-uuid>-<project-name>/
            └── <scan-type>/
                └── <ref-or-pr>/
                    └── <timestamp>_<scan-uuid>.zip
Each path segment is defined as follows:

​
Example file path

my-bucket/endor/abc123-prod-exporter/acme-corp/6efgh-pythonrepo/schedule/main/20251215T143025Z_xyz789.zip

​
Manage the S3 exporter

You can list, update, and delete S3 exporters using the Endor Labs API.
Run the following command to list all exporters in your namespace.
endorctl api list --namespace=<namespace> --resource=Exporter
Run the following command to update an existing exporter. Use the --field-mask parameter to specify the fields to update.
endorctl api update \
  --namespace=<namespace> \
  --resource=Exporter \
  --name=<exporter-name> \
  --field-mask "spec.s3_config.region" \
  --data '{
    "spec": {
      "s3_config": {
        "region": "us-west-2"
      }
    }
  }'
You must disassociate the exporter from any linked scan profiles before deletion.
Run the following command to delete an exporter.
endorctl api delete --namespace=<namespace> --resource=Exporter --name=<exporter-name>
