Thru: Large Secure File Transfer

Many people need to transfer large files, on the order of 100MB and up. For example:

  • Hospitals sending patient records.
  • Architects exchanging building plans.
  • Engineers collaborating on product designs.

However, it's tough to transfer large files electronically. Email often can't handle anything more than 10MB or 20MB, and FTP sessions get broken and don't recover well.

Some companies offer specialized solutions. Thru is an example.


  • Thru Server: Secure Content Delivery and Archiving System.
  • File transfers up to 25GB.
  • File synchronization.
  • Encryption. Useful if the file needs to be protected from unauthorized eyes.
  • Email and file archiving.
  • Audit trails.
  • Server available since 1992 on Unix platforms, on Windows since 2002.
  • Outlook and Notes plugins.
  • Available as customer-premises software or SaaS.
  • Web services API for integration with third-party applications.

List Pricing

  • On-premises software: Server is $18K, plus about $20 per seat.
  • SaaS: Priced per seat, with an additional price for extra space. For example, 1,000 seats are $5/seat/month, including 60GB of storage. Above 60GB is $10 to $15 per GB.

Main Competition

  • Tumbleweed, Ipswitch, Accellion, GlobalScape, Sterling Commerce.

Company and Finances

  • 45 employees.
  • Founded 2002 from merger of a Silicon Graphics spin-off and an SGI reseller.
  • Not profitable.
  • Around $5M of external investment from angel investors. Currently raising Series A from VCs
  • Ferris Research estimates revenues at $4M annually.

    rsync is free. While the user interface for Thru is probably vastly easier for many people, rsync offers most of the same features. Any opinion on how they compare in terms of reliability?

    Joe–Thanks for raising rsync. I’m sorry, I don’t know how they compare in terms of reliability–david

    Rsynch is a sychronization application great for data backups available as a GNU package for Unix, ports to the other major OS exist such as Mac, Windows, Linux. It might be easy to construe rsynch as being a free alternative to Thru, they are in fact very different types of solutions designed for different applications. Although the system can indeed be used for backup/archiving purposes, Thru’s capabilities are centered around large file transfer on a domestic and global basis, archiving, and GRC type reporting. The support for ad-hoc data exchange via email & mobile communication, dedicted networks, and SOA type applications housed in SAS 70 – Type II datacenters with matching SLAs make it as reliable as any that I can see.
