Quality Engineering

You can't hotfix hardware in the field

IoT products fail across four layers at once — device, firmware, connectivity, and platform — and a defect that ships in firmware can mean a recall, not a patch. We test connected products end to end, with device security in scope from day one.

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

Device & firmware testing

Functional coverage across device states: provisioning, pairing, OTA updates, power interruption, factory reset — the lifecycle events where firmware breaks.

Connectivity & protocol testing

Behavior under real network conditions — latency, loss, handoffs — across BLE, Wi-Fi, MQTT, and cellular paths.

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 by our offensive security practice, not a checklist.

Tools & standards

Protocols
BLE, Wi-Fi, MQTT, cellular; network condition simulation
Security
Burp Suite Pro, Nmap, Nessus — device and API assessment

What you receive

  • Device-lifecycle test coverage with evidence per state transition
  • Connectivity behavior report under degraded network conditions
  • End-to-end integration validation (device → cloud → app)
  • Device security findings with severity and remediation guidance

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
