SFTP Gateway v3.7.4: 3x Faster SFTP to Cloud Uploads and Local Storage Support

SFTP Gateway v3.7.4 delivers significantly faster SFTP to cloud uploads for Amazon S3, Azure Blob Storage, and Google Cloud Storage, along with new flexibility for hybrid storage environments.

SFTP Gateway provides a simple, secure, and scalable solution for granting SFTP users access to cloud storage locations. It’s deployed in your private cloud environment. We don’t touch your data or your infrastructure.

3x Faster Upload Performance

Upload throughput has improved threefold through the use of batch write methods and optimized memory buffering. Whether you’re transferring files to Amazon S3, Azure Blob Storage, or Google Cloud Storage, you’ll see the benefits immediately.

New Local Mount Cloud Connection

For organizations with on-premises storage requirements, SFTP Gateway v3.7.4 introduces a Local Mount Cloud Connection. This provides greater flexibility in hybrid environments where data needs to be stored locally, rather than or in addition to cloud destinations.

Enhanced Audit Logging

Audit logs now include Correlation IDs and success status for each transfer. Use the Correlation ID to trace files through post-processing workflows back to their original upload event.

Security and Stability Updates

This release includes several critical updates:

  • Ubuntu base image updated to v24.04
  • Backend libraries updated to address CVE-2025-55754
  • Public key encryption algorithms now properly respect selected settings
  • Improved retry logic in Cloud Storage SDKs for better resilience during API throttling

Get Faster SFTP to Cloud Uploads and More Now

SFTP Gateway v3.7.4 is now available on the Google Cloud Marketplace and will be rolled out soon to the AWS and Azure Marketplaces. SFTP Gateway comes with a 30-day free trial on all three cloud marketplaces.
