ECU-level runtime protection and continuous integrity attestation for production firmware—designed for real-time constraints and modern vehicle attack paths.
Connected vehicle interfaces (telematics, OTA, diagnostics, shared software) expand the attack surface. Once attackers gain access, they can pivot across in-vehicle networks to ECUs—where runtime tampering and calibration manipulation can create real operational risk.
Detect runtime modifications and integrity drift across critical code and data.
Identify and block unauthorized runtime behaviors that correlate with exploitation.
Secure high-value memory regions with policy-based write controls for development and production modes.
Real-time security event generation for local logging or centralized analysis
Symbiote is embedded into the ECU firmware image and activates at defined execution points. It verifies integrity, monitors for exploit-like behavior, and records security events—adapting to system load to preserve real-time timing.
Identify memory corruption and code-reuse signals in real time.
Protect high-value parameters from unauthorized writes during service or operation.
Reduce exposure between patch cycles with runtime signals.
Generate defensible logs for forensics and internal audits.
Security expectations are trending toward runtime monitoring and evidence, alongside secure development and update practices.
Symbiote delivers integrity signals and event timelines for defensible reports and response workflows without requiring constant connectivity.
No. Symbiote can be applied late in the build flow to final firmware images. Source can accelerate integration, but it’s not required. Protections run via defined execution points and an adaptive scheduler that backs off under load. Policies can be tuned to meet timing goals. Logs can be collected locally and extracted at service time. Connectivity helps, but offline workflows are supported. Start with visibility on defined regions/actions, then refine policy by operational state (dev/in-cal/prod). The goal is protection without breaking serviceability. Symbiote’s runtime defense currently adds only a 1% to 3% performance overhead.
If you’re balancing compliance timelines, real‑time constraints, and long patch cycles, we’ll show a path from a single ECU integration to a scalable program.
