Red Balloon Security Symbiote is a firmware-embedded runtime protection solution designed for embedded devices and critical systems. The product operates at the firmware level to provide continuous integrity attestation and runtime defense without requiring source code access or additional hardware resources. Symbiote monitors memory, control-flow, and process behavior in real time to detect and respond to runtime violations. The solution is OS-agnostic and can be deployed directly into device firmware. When attacks or integrity violations are detected, Symbiote can execute policy-driven responses including blocking unauthorized execution, initiating device reboots, or generating alerts. The product addresses threats including memory corruption, process tampering, persistence mechanisms, and integrity drift. It provides continuous integrity checks for both code and data, detecting runtime manipulation as it occurs on the device itself. Symbiote can be paired with Red Balloon Security's Runtime Monitoring capabilities (AESOP) to provide fleet-wide telemetry, centralized reporting, and alert routing for SOC workflows. This combination enables organizations to gain visibility across their entire device fleet while maintaining on-device protection. The solution is designed for embedded systems, industrial control systems, and other critical infrastructure devices where traditional endpoint security solutions may not be applicable due to resource constraints or operational requirements.
