Firmware assessment
Review of embedded Linux, RTOS images, boot assumptions, update mechanisms, exposed services, and local debug paths.

Services
Review of embedded Linux, RTOS images, boot assumptions, update mechanisms, exposed services, and local debug paths.
Assessment of pairing flows, authentication boundaries, proprietary protocols, telemetry, cloud APIs, and management channels.
Security findings translated into engineering tickets, validation steps, release guidance, and customer-facing assurance notes.
When it fits
Assess firmware, management interfaces, and update flows before a launch or major customer pilot.
Review a device, appliance, or software-controlled system before bringing it into a sensitive environment.
Produce practical evidence for security questionnaires, enterprise reviews, and remediation follow-up.
Confirm whether a suspected weakness is exploitable, product-relevant, and worth prioritizing.
Output
Target inventory, assumptions, access requirements, and areas intentionally out of scope.
Risk-ranked issues with reproduction notes, impact, affected components, and remediation guidance.
Walkthrough with owners so fixes can be sequenced against release and platform constraints.
Confirmation of resolved items and notes for accepted risk or follow-on work.
Approach
Start with the product goal, target environment, threat model, and what decision the review needs to support.
Work from firmware images, test hardware, docs, logs, source snippets, or remote access when useful.
Deliver privately. Public disclosure or publication only happens when explicitly agreed in advance.
