6 Best TFTP Servers

By Staff Contributor on May 19, 2020

The Trivial File Transfer Protocol (TFTP) is a file-transfer protocol suited to the transfer of firmware updates, the movement of system images, and similar tasks requiring functionality over form. TFTP is more lightweight than the File Transfer Protocol (FTP), with a smaller footprint. It’s also faster and easier to implement and configure, particularly when performing large-scale transfers of workstation configurations, files, updates, and more. A notable disadvantage of TFTP, however, is it doesn’t offer optimal security and is more vulnerable than FTP.

TFTP can be used in several ways, including to back up network or router settings configurations quickly and simply. You can also use it to save iOS disk images and deliver upgrades. TFTP even allows you to remotely boot a system without a hard drive. By using TFTP, you can rapidly perform tasks otherwise slowed by carting a hard drive to multiple machines.

Although there are numerous benefits associated with using TFTP for certain tasks, the process can be error-prone and complex. TFTP servers may be the solution to this issue, streamlining your TFTP activities and increasing your control over them. This guide provides a list of the best TFTP servers on the market, and ranks SolarWinds® Engineer’s Toolset as the most versatile, user-friendly, and suitable for business use. Read on to find out how the other TFTP servers measure up.
