The Threat Stack Cloud Security PlatformⓇ (CSP) supports the export of batched files to an AWS S3 bucket with Object Lock enabled. No additional permissions are required. See the Amazon S3 Object Lock documentation for S3 Object Lock configuration instructions.
The S3 Object Lock configuration includes a retention period during which no files can be removed from your S3 bucket. Consider the volume of data you receive from the Threat Stack CSP when integrating data portability with an Object Locked S3 bucket.
