IoT Ecosystem Security Audit

Device, firmware, protocol and backend checks for connected products and factories.

Request IoT Audit

Overview

IoT systems combine embedded firmware, local networks, gateways and cloud services. Our IoT audits examine firmware, device interfaces, protocol security, gateway hardening and backend API controls to reduce attack surface across the ecosystem.

Why companies need IoT audits

Connected devices often expose unexpected interfaces, hard-coded secrets or insecure update mechanisms. A comprehensive audit prevents device compromise, supply-chain abuse and operational disruption.

Key benefits

Identify firmware vulnerabilities and unsafe storage of secrets

Harden device-to-cloud communication and gateway policies

Improve OTA and supply-chain security for safer deployments

Scope — What we test

Firmware static analysis, debug interfaces, unsecured storage, insecure bootloaders, protocol (MQTT/CoAP) misconfigurations, gateway segmentation, cloud API exposures and update/OTA processes.

Methodology

  1. Device inventory & threat modelling
  2. Firmware extraction & static analysis
  3. Protocol fuzzing & runtime checks
  4. Gateway/network segmentation review
  5. Backend API & cloud integration testing
  6. Remediation plan and retest

Deliverables

An audit report with device-level findings, firmware PoCs, recommended segregation and secure OTA guidance, threat-model mapping and prioritized remediation steps.

Frequently asked questions

Common questions we hear before starting an assessment — click a question to reveal a short, clear answer.

Small apps: 1–5 days. Medium: 5–10 days. Complex systems: custom timeline.

We avoid destructive checks in production and schedule high-risk tests in staging when possible.

No — blackbox tests work. Source access enables deeper code review.

Yes — PoCs, prioritized fixes and developer-focused guidance are included.

Yes — retest packages validate fixes.

Executive summary, prioritized findings, PoCs and workshop walkthroughs.

Yes — mutual NDAs and secure report distribution are standard.

Test accounts, scope and any available docs (API/OpenAPI) are helpful.

Physical devices are ideal; if unavailable we can test via provided firmware images and staging gateways.

Yes — we follow safety-first testing and coordinate with operations teams for OT/ICS environments.
