Securing the OT Perimeter: Rethinking File Transfer as a Critical Security Control

Most organizations connecting IT and OT environments believe their file transfer processes are “secure.” Encryption is in place. Network controls are defined. Access is restricted.

But in practice, risk doesn’t come from missing controls. It comes from how data actually moves: manual workarounds, unmanaged scripts, uncontrolled third-party access, and transfers that operate outside consistent policy enforcement.

Securing the OT Perimeter is a guide for organizations operating at the OT boundary—where legacy systems, external connectivity, and real-world constraints create the highest exposure. It helps you evaluate whether your approach to file transfer actually reduces risk as data moves between IT, OT, and third-party environments.

What this guide covers

  • Why risk concentrates at the OT perimeter, not inside the systems themselves
  • Where data movement breaks down across IT, OT, and external connections
  • How unmanaged transfers introduce exposure in otherwise controlled environments
  • The role of secure, governed file transfer in reducing operational and security risk

Get a clear, experience-driven framework to assess how your organization secures data movement without disrupting critical systems and whether your current approach prevents issues or simply works around them.
