IronClad Secure Flight Controller

A Platform-Agnostic, Open-Architecture, Cybersecure UAS Flight Controller

The American-made, cybersecure IronClad SFC provides cutting-edge avionics sensors and computing capabilities coupled with reliable, customized packages of open-source autopilot software.

American-Made, US Government-Vetted:

  • Designed and manufactured by a Service-Disabled, Veteran-Owned Small Business located in Columbus, OH

  • Developed and vetted in conjunction with the US Department of Homeland Security and US Department of Defense

  • NDAA 2020 Section 848 Compliant

  • Passed multiple third-party cybersecurity assessments

Open But Secure:

  • Runs non-proprietary, open-source autopilot and communication software with added security enhancements

  • Engineered from the ground-up with hardware and software-based cybersecurity features

  • Security features include embedded hardware security, anti-tamper, secure boot, and encrypted file systems, onboard encryption of control and telemetry streams

More Than Just an Autopilot:

  • Deeply integrated edge-computing capability for combined flight control, video processing and artificial intelligence/computer vision applications

  • Compatible with wide variety of third-party radio solutions

  • Integrated hardware-in-the-loop simulation capability for risk-reduced flight control refinement and payload development testing


Example of Hardware-in-the-Loop simulation on a newly integrated UAS platform


Most other UAS flight controllers/autopilots are advertised as "plug-and-play" and "modular", making it seems as if you can fly (and integrate payloads) with minimal effort


Every new platform, payload and mission application requires significant engineering, integration and testing efforts


Asymmetric's team of US-based, security-cleared engineers built the IronClad SFC from the ground up and can help you quickly configure your UAS so it is secure, reliable and on the cutting-edge

The Asymmetric and IronClad Difference:

IronClad SFC has been successfully integrated on multiple US Government-operated and commercial UAS platforms -
