 ## Security Considerations
 
-### S3 Bucket Permissions
+### IAM User Permissions
 
-Configure your S3 bucket with a least-privileged policy:
+When using AWS S3 or S3-compatible storage providers, ensure that the IAM user associated with your `S3_ACCESS_KEY` and `S3_SECRET_KEY` credentials has the necessary permissions to interact with your bucket. Without proper permissions, file uploads and retrievals will fail.
+
+The following IAM policy grants the minimum required permissions for Formbricks to function correctly. This policy is also used in the bundled MinIO integration:

+    }
+  ]
+}
+```
+
+<Note>
+  Replace `your-bucket-name` with your actual S3 bucket name. The first statement grants object-level
+  operations (upload, retrieve, and delete files), while the second statement allows listing bucket contents.
+</Note>
+
+### S3 Bucket Policy
+
+In addition to IAM user permissions, configure your S3 bucket with a least-privileged bucket policy to ensure security:
 
 1. **Scoped Public Read Access**: Only allow public read access to specific prefixes where needed
 2. **Restricted Write Access**: Only your Formbricks instance should be able to upload files
