Why should you
choose ESTA?

The simple nature of the software allows for easy integration into existing systems, as well as interoperability with other software solutions, whether they are legacy or bleeding edge products.

If your connection drops, ESTA will re-establish a connection when it can, and resume your transfer right where it left off, instead of restarting at the beginning, thus ensuring minimal bandwidth usage despite the stops and starts. ESTA does the heavy lifting for you, allowing you to focus on the data, instead of focusing on how to get it from place to place. No longer will you have to rely on stop-gap solutions and command line utilities. Set it up once, and itíll run forever.

ESTA owes its minimal bandwidth usage to data compression, a minimal binary transfer protocol, and its segmented transfer mechanism. These systems all act in concert to get your data there on time, intact, with minimal cost and maximum security. We do all of this while, at the same time, ensuring that the impact to your users is negligible. Performance is key in application scaling, and so the ESTA solution targets minimal memory usage, making sure that your users, applications, and servers are left to perform their primary functions, un-impacted by background file transfers.

A Proven Solution

ESTA has successfully transferred millions of files, a significant portion of which were delivered via satellite, all without a single loss of data.
Safe and Dependable

Your data is secure against prying eyes, even over unreliable and untrusted network connections.
Cost Effective

ESTA provides you with the most functionality, using minimal system resources, maximizing your investment.

The Big Picture

Whether you are located out at sea, in the trenches, an industrial site, or simply the leisure of your own home, ESTA will ensure that all your file transfers are secure and reliable. Regardless of the scenario, ESTA is built to handle the most unreliable network conditions and operate with a low profile, providing results you can depend on without compromising your computer's performance.

The Inner Workings

ESTA transfers data in discreet chunks, using secure hash algorithms to validate data receipt, discover potential tampering, and minimize data retransmission in the event of corruption or disconnections. This allows us to resume a file transfer where it left off rather than start over from scratch, as is required by other older protocols.

This system also ensures maximum data integrity by validating data as it's received and written to the disk, and validating the whole file when the transfer completes, providing you with peace of mind, secure in the knowledge that your data is safe.

A secure TLS tunnel is used to protect all communications between peers. We implemented industry standard PKI infrastructure to provide reliable identification and secure communication, so you can rest comfortably knowing that your data goes where you want it to go, and nowhere else. High bit-depth asymmetric encryption algorithms provide a secure basis for peer identification and are used worldwide by critical security industries, including banking, health care, and even government security sectors.

Diagram of Inner Workings
After ESTA establishes a connection and the identity of who it's talking to, it creates a hash and computes a digital signature of every file it intends to send. This is used to prevent sending the same file twice and to validate that the file is properly received by the intended recipient.

We use compression and encryption algorithms in the transportation of your data to minimize the bandwidth used, and to ensure a speedy delivery of your data. Our binary transfer protocol has features that allow resumption of interrupted file transfers, ensuring that your connection isn't tied up sending the same thing twice.

After receiving a file and validating that the file matches what was sent against its digital signature, we move the file to its intended destination and ensure that it's properly added to the auditable logs, allowing you to track receipt of every file that's moving through the system.

Simplicity Begets Productivity
And so Emprise Secure Transfer Agent doesn't require cumbersome client software for your users to move files around. Transferring files with ESTA can be accomplished by simply dragging and dropping files within the Microsoft Explorer file manager.

  • Drag, drop, and done.
  • File Explorer Interface.

Reliability Is
Absolutely Essential

Which is why Emprise Secure Transfer Agent ensures maximum data integrity by validating files before, during, and after transport. If you have an unreliable internet connection, ESTA will save you time and energy by resuming your file transfers exactly where they left off, instead of re-sending the entire file again.

  • Automatic file resume.
  • Periodic connection retries.
  • Resumes exactly where it left off.

Security Is Imperative
Emprise Secure Transfer Agent uses the industry-standard TLS protocol to ensure that your files are safe from prying eyes, and a secure public/private-key based certificate system to ensure that your files aren't intercepted along the way. Detailed audit records are standard, logging every connection and more.

  • 1024-bit or 2048-bit Public/Private key cryptography.
  • Certificate based peer identification.
  • TLS.
  • FIPS Compliance Option.
  • Detailed Audit Reports.

Flexibility Allows
For Future Expansion

Emprise Secure Transfer Agent's flexible routing system allows you to set up computers to be used as relay points, also known as hops or switching points. This allows you to manage the flow of files over network architectures which might not allow a direct connection between two computers.

  • Dynamic message routing system.
  • Multi-tiered options available
