A company collects and stores research data in an Amazon S3 bucket and processes the data in the AWS Cloud. The company must share the data with employees worldwide. The solution should be secure and minimize operational overhead. Which solution meets these requirements?

S3 File Gateway provides a file interface to S3, allowing employees to access S3 objects as files through standard file protocols (NFS or SMB). This simplifies access for a global workforce and minimizes operational overhead as it integrates with existing file systems. It's secure because access can be controlled via gateway settings and network configurations. Using Lambda to create presigned URLs is less practical for ongoing, widespread access by many employees, as URLs expire and require re-generation. Creating individual IAM users and policies for each employee is high operational overhead and exposes the AWS console, which might not be ideal for simple file access. AWS Transfer Family SFTP endpoints are designed for secure file transfer over SFTP, FTPS, or FTP, which is different from directly accessing files as if they were on a local network share, and might be overkill for simple read access.
