Transmit macOS File Transfer App Offers Secure Multi‑Cloud Connectivity – $45 One‑Time Purchase
What Happened – Transmit, a macOS‑only file transfer client, received a positive review highlighting its support for SFTP, WebDAV, and a broad set of cloud storage services (Amazon S3, Backblaze B2, Dropbox, Google Drive, Azure, OneDrive, etc.). The reviewer notes the app’s SSH‑key authentication for SFTP and a polished GUI, but warns that Google Drive integration will be discontinued.
Why It Matters for TPRM –
- Demonstrates that a modest‑cost third‑party client can provide strong encryption (SFTP + SSH keys) for data in transit.
- Highlights a potential future loss of functionality (Google Drive) that could affect business continuity for vendors relying on that integration.
- Offers a concrete example of a vendor‑managed tool that should be evaluated for security posture, licensing, and support lifecycle.
Who Is Affected – Technology / SaaS firms, media & entertainment companies, design agencies, and any organization that transfers large files from macOS workstations to cloud or on‑prem servers.
Recommended Actions –
- Add Transmit to your approved‑software inventory and verify licensing compliance.
- Review the app’s SSH‑key handling policies and ensure key rotation aligns with your organization’s standards.
- Monitor the upcoming Google Drive deprecation; plan alternative workflows or migration paths.
Technical Notes – The app uses native SFTP (SSH v2) with optional key‑based authentication, WebDAV over HTTPS, and proprietary APIs for cloud services. No known CVEs are associated with the current version (as of June 2026). Source: ZDNet Security – Why I happily paid for the Transmit MacOS app
