Device & firmware testing
Functional coverage across device states: provisioning, pairing, OTA updates, power interruption, factory reset, the lifecycle events where firmware breaks.
Quality Engineering
You can't hotfix hardware in the field
The production run is scheduled, and whatever ships in that firmware is what your customers will hold for years. IoT products fail across four layers at once (device, firmware, connectivity, and platform), and a defect baked into hardware means a recall instead of a patch. We test connected products end to end, with device security in scope from day one.
Engineering-led cybersecurity and quality engineering since 2020, delivered by 100+security & quality engineers on platforms we build and run ourselves.
Field failures cost warranty claims, RMAs, and channel trust; connectivity edge cases (flaky networks, power loss mid-update) are exactly what lab-only testing misses. And an insecure device is a liability with your logo on it.
What we do
Connectivity & protocol testing
Behavior under real network conditions (latency, loss, handoffs) across BLE, Wi-Fi, MQTT, and cellular paths: the conditions that decide how the product behaves in a customer's hands.
Platform & app integration
The full chain: device to cloud to mobile app, tested as one system with state consistency verified at every hop.
IoT security testing
Device-side security assessment (exposed services, credential storage, update signing, API trust) run hands-on by our offensive security practice.

Evidence
QE for software that ships in vehicles
Our automotive engagement runs quality engineering for software where field failures are expensive and patching is slow, the same constraint embedded and IoT products live with.

Ways to engage the same senior bench
Buy it as a scoped project, embed it in your team, or run it as a managed service. The engineers and the governance stay the same, whichever shape fits.
Scoped project
A defined piece of work with a fixed outcome (a test suite built, a release hardened, a backlog cleared), delivered by our team and handed over with documentation.
Embedded QE
Our engineers work inside your sprint teams, on your tools and cadence, owning quality alongside your developers rather than testing from the outside.
Managed QE service
We own the discipline as an ongoing service (coverage, execution, and reporting), scaling the bench up or down as your release pressure moves.
Who this is for
- Hardware startups approaching production runs where firmware defects become recalls
- OEMs/ODMs shipping connected products under a customer's brand
- Product teams whose devices work on office Wi-Fi and fail in the field
Common questions
Do you test device security too?
Yes, and by the people who attack devices for a living: exposed services, credential storage, update signing, and API trust are assessed by our offensive security practice, alongside lifecycle, connectivity, and device-to-cloud integration testing.
Why does IoT need testing a normal app doesn't?
A shipped device can't be quietly patched, and it lives in the field on networks you don't control. Firmware, connectivity dropouts, update integrity, and the device-to-cloud trust boundary are failure modes a web pentest or app test never reaches.
Who actually does the work?
Senior engineers from our own team, and the ones who scope your engagement stay on it through delivery. Across the practice, 63% of our engineers hold industry certifications, spanning ISTQB, AWS, CISSP, CEH, and eCPPT.
In the assurance loop
Firmware cannot be patched as casually as a web application, so verification carries more weight. Findings are retested on the device before release and the checks stay in the suite. See how the loop connects →
Test it before the production run
Bring the device matrix and the ship date. Lifecycle, connectivity, and security coverage get scoped to fit the window you actually have.
