Best Secure File Transfer Software

You probably realize that moving corporate data across the internet in plain text is a vulnerability. Thanks to data protection legislation and industry standards, you also need to be careful about transferring Personally Identifiable Information (PII) about your customers, employees, and associates.

Insider threats and Advanced Persistent Threats (APTs) mean that you can’t even be lax about security for file transfers on your own private network. PII needs to be shielded from unintentional disclosure and keeping internal file transfers secure ensures that technicians can’t view data in transit.

Overall, you need to keep data security tight all over your IT system and file transfer mechanisms are part of that environment.

Here is our list of the seven best file transfer software packages:

  1. SolarWinds Serv-U Managed File Transfer Server EDITOR’S CHOICE This file transfer software is a server and has a free companion FTP client available, offering a full file transfer suite. It runs on Windows Server and Linux.
  2. (FREE TRIAL) A cloud-based file management platform that facilitates file sharing, transfers, and storage.
  3. ExaVault (FREE TRIAL) Use FTPS and SFTP for file movements with this server or use the cloud service to mail out access links to files without moving them.
  4. Citrix ShareFile This cloud platform manages secure file transfers and can be used for process automation.
  5. FTP Today A file server system that supports secure file management actions, including file transfers. This is a cloud service.
  6. ActiveBatch This is a process automation system that includes secure file transfer utilities. Installs on Windows, a VM, or a private cloud.
  7. Accellion Kiteworks This is a suite of modules for content protection that offers a secure file transfer system. It is implemented as a cloud platform.

What qualifies as secure file transfer software?

A secure file transfer software package needs to incorporate host authentication and transmission encryption. Typically, File transfer systems offer FTPS (File Transfer Protocol/Secure), which is protected by Transport Layer Security (TLS), and SFTP (Secure File Transfer Protocol), which is protected by the Secure Shell (SSH).

Security isn’t just about encryption; it is also about accountability. File transfer software needs to include action logging in order to be fully compliant with HIPAA, PCI DSS, GDPR, and other data protection standards. The audit value of file transfer logging is only achieved by making each action attributable. That requirement can’t be implemented within your file transfer software without user identification.

The log records of your secure file transfer software should identify each file transfer event with the user account of the transferrer, the source and destination address, termination status, and a timestamp. Many log analyzers and SIEM tools rely on feeds from file transfer software logs for security scanning.

The Best Secure File Transfer Software

The issue of security isn’t specifically an indication of the best secure file transfer software, it is a candidate requirement to just be any file transfer software package that can be regarded as secure. To narrow down the field to a list of the best secure file transfer software packages we applied more scrutiny.

What should you look for in secure file transfer software? 

We reviewed the secure file transfer software market and analyzed the options based on the following criteria:

  • Multiple secure protocol options
  • The option to integrate file transfer commands in scripts for task automation
  • Integrations into well-known third-party software and cloud platforms
  • A reputable producer
  • Logging and auditing
  • The ability to assess the software for free
  • A good balance between functionality and price

Although secure file transfer software is an essential buy, it won’t be your main software purchase, so getting a good deal on your file transfer software is important. However, you can’t afford to use a cheap package that won’t provide sufficient security.

Managing the file transfer fully in-house greatly simplifies the legal requirements for data protection standards., Outsourcing file management functions to third-party businesses complicates the accountability requirements of systems such as PCI DSS and HIPAA because the managed service provider is legally jointly liable in the event of data disclosure. The security options in this system fully protect all files during transfer and the event logging features make security auditing easy.
