Scope

Focused security work for product and engineering teams.

Firmware assessment

Security review of embedded Linux, RTOS, bootloaders, update flows, and device services.

Protocol analysis

Assessment of proprietary protocols, device pairing, transport security, telemetry, and management planes.

Product assurance

Security findings translated into clear engineering changes, validation steps, and release guidance.

Approach

Small engagements, clear artifacts, useful security outcomes.

01

Define the target, threat model, access level, and useful proof points.

02

Analyze firmware, services, device behavior, and exposed interfaces.

03

Deliver findings with risk context, validation notes, and remediation options.
