// IoT SOLUTIONS · SECURE BY DESIGN
Smart devices designed through an attacker’s lens.
Kritera treats security as the center of the IoT architecture, not an afterthought. From embedded systems and cloud integrations to custom smart-device design and firmware hardening, our solutions are aligned with ETSI EN 303 645 and the OWASP IoT Top 10.
Service Scope
Hardware & Embedded Design
- PCB and embedded system design
- STM32, ESP32 microcontroller firmware
- Secure boot, secure element integration
- Signed firmware and OTA update pipelines
Connectivity & Cloud
- MQTT/CoAP/LwM2M protocol architecture
- TLS 1.3 certificate-based device identity
- Azure IoT Hub / AWS IoT Core integration
- End-to-end encrypted edge-to-cloud data flows
A Security-First IoT Philosophy
A typical IoT device has a 5-10 year operational life. The threat landscape changes dramatically over that period. That is why secure boot, hardware root of trust (HRoT), cryptographic identity, signed firmware, secure OTA updates and per-device secrets must be design-time decisions — not features bolted on later.
Our penetration tester team runs “break attempts” at every stage of development: physical access, JTAG/SWD debug port exploitation, side-channel analysis, firmware reverse engineering. Vulnerabilities are surfaced and resolved before the product reaches the field.
