IronClad Secure Flight Controller

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

The American-made, cybersecure IronClad Secure Flight Controller 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 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

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.

IronClad and the Asymmetric Difference

IronClad SFC has been successfully integrated on multiple US Government-operated and commercial UAS platforms. Let Asymmetric help you enhance and secure your drone.
