Product security assessment

Security review for firmware, devices, and control planes.

Bitfield Research helps engineering teams evaluate connected products before release, procurement, or customer security review.

Services

Independent review for systems with real-world constraints.

Firmware assessment

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

Device and protocol review

Assessment of pairing flows, authentication boundaries, proprietary protocols, telemetry, cloud APIs, and management channels.

Hardening support

Security findings translated into engineering tickets, validation steps, release guidance, and customer-facing assurance notes.

When it fits

Useful when a product needs a second technical read.

01

Pre-release review

Assess firmware, management interfaces, and update flows before a launch or major customer pilot.

02

Vendor diligence

Review a device, appliance, or software-controlled system before bringing it into a sensitive environment.

03

Customer assurance

Produce practical evidence for security questionnaires, enterprise reviews, and remediation follow-up.

04

Issue validation

Confirm whether a suspected weakness is exploitable, product-relevant, and worth prioritizing.

Output

Clear artifacts for engineering, security, and procurement teams.

Assessment plan

Target inventory, assumptions, access requirements, and areas intentionally out of scope.

Findings report

Risk-ranked issues with reproduction notes, impact, affected components, and remediation guidance.

Engineering readout

Walkthrough with owners so fixes can be sequenced against release and platform constraints.

Retest memo

Confirmation of resolved items and notes for accepted risk or follow-on work.

Approach

Lightweight process, private by default.

01

Start with the product goal, target environment, threat model, and what decision the review needs to support.

02

Work from firmware images, test hardware, docs, logs, source snippets, or remote access when useful.

03

Deliver privately. Public disclosure or publication only happens when explicitly agreed in advance.

Review surface

Common areas covered during an assessment.

Update integrity Authentication boundaries Debug exposure Secrets handling Transport security Management APIs Telemetry paths Fleet operations
