I will perform iot firmware security audit and risk analysis
IoT Security Specialist, Embedded Firmware Developer
I build secure IoT firmware and uncover vulnerabilities in smart devices.
With hands-on experience in ESP32/STM32 (ESP-IDF, FreeRTOS), I focus on security from day one. I don’t just ship working code...
About this Gig
Is your IoT product ready for production? Most devices have hidden risks.
I'm an embedded systems engineer specializing in security-focused
analysis of IoT firmware and device communication.
What I do:
- Analyze firmware for hardcoded credentials, API keys, and insecure logic
- Review device communication (MQTT, HTTP, BLE, CoAP) for data exposure risks
- Evaluate OTA update mechanisms (integrity, rollback, update flow)
- Identify weaknesses in authentication and data handling
- Provide a structured report with severity levels (CVSS) and clear recommendations
Platforms I work with:
ESP32 / ESP8266 / STM32 / Raspberry Pi / Nordic nRF52
Protocols: MQTT, BLE, Zigbee, WiFi, LoRa, CoAP
Who this is for:
- IoT startups preparing for launch
- Hardware companies needing pre-release validation
- Product teams after firmware updates
- Teams concerned about device data security
Every audit includes a written report with actionable fixes.
Premium package includes a detailed hardening plan with practical implementation guidance.
Message me with your device details to get started.

FAQ
Do I need to ship my device to you?
Not necessarily. For firmware analysis, you can provide the firmware binary (.bin/.hex). For communication analysis, I can guide you on capturing device traffic using simple tools, or you can ship the device if needed.
What do I get as a deliverable?
A structured PDF report with identified risks, severity levels (CVSS), and clear remediation recommendations. Where relevant, I include practical examples to help you fix the issues.
Can you also develop or fix the firmware?
Yes. I also provide firmware development services (ESP32/STM32). I can both identify issues and help implement secure solutions.
What if no issues are found?
You will still receive a full report describing what was analyzed and confirmation that no significant risks were identified. This is valuable for validation before production.
Is my firmware/code kept confidential?
Absolutely. Your firmware and project details are handled confidentially. I can sign an NDA if required.
