Red Balloon Security offers firmware‑level protection for embedded devices used in critical commercial and government systems. Its Symbiote suite continuously attests code and memory integrity at runtime without requiring source code or hardware changes, using techniques like binary reduction, structure randomization, and syscall randomization across many operating systems and instruction set architectures. Real‑time fleet monitoring (AESOP) provides integrity alerts and forensic data to help security teams protect OT device fleets.

Problem
Embedded devices and firmware in critical systems often run without source code access or hardware modifications, leaving them vulnerable to exploit chains, memory corruption, and unauthorized code execution. Traditional security measures are insufficient for the diverse operating systems and instruction set architectures used in these environments, resulting in high risk for both commercial and government deployments.
Solution
Red Balloon Security provides firmware-level protection for embedded devices through its Symbiote suite, which continuously attests code and memory integrity at runtime without requiring source code or hardware changes. The solution combines firmware hardening techniques—such as Autotomic Binary Reduction, Binary Structure Randomization, and syscall randomization—to shrink and randomize the attack surface. Real-time monitoring and alerting (AESOP) deliver fleet-wide visibility, forensic context, and integration with SIEM/IDS workflows. The technology is OS-agnostic and supports a wide range of instruction set architectures, enabling deployment across diverse critical infrastructure and OT environments.
Target Audience
Primary customers are manufacturers and operators of embedded systems in critical sectors such as industrial control, automotive, aerospace, and government infrastructure, as well as security teams responsible for protecting OT device fleets.
Features
- Autotomic Binary Reduction removes unused code to reduce attack surface and improve performance
- Binary Structure Randomization randomizes code and data layout, thwarting memory‑based exploits
