Platanor Technologies

What we build

Expertise

We combine deep embedded engineering with real-world experience building secure, production devices.

Embedded Platforms & Firmware

  • STM32 and Nordic nRF microcontrollers
  • RTOS-based systems (Zephyr, FreeRTOS)
  • Custom communication protocols
  • Industrial and hardware interfaces (RS-485, CAN, UART, SPI, I2C)

We design firmware for reliability, determinism, and long-term maintainability in production environments.

Device Security & Authentication

  • Hardware root of trust and secure boot
  • Secure key storage and provisioning
  • Device identity, attestation, and authentication
  • FIDO2 / passkey-based authentication systems
  • Public Key Infrastructure (PKI) and certificate workflows

We design security mechanisms that operate within real hardware constraints while meeting production requirements.

Connected Systems, IoT & Device Security

  • Cloud-connected embedded devices
  • Secure device onboarding and provisioning
  • OTA firmware updates and lifecycle management
  • Device fleets and large-scale deployments
  • Industrial and infrastructure monitoring systems

Our focus is end-to-end device ecosystems - not isolated firmware components.

Selected Experience

Most projects are delivered under NDA, but our team has extensive experience building production systems including:

  • Industrial PLC-class controller - real-time industrial device with secure communication and hierarchical device management
  • Hardware FIDO security key - embedded authenticator with secure key storage and cryptographic operations
  • E-ink embedded device - low-power system with optimized firmware and reliable update mechanisms
  • Secure authentication ecosystem - end-to-end system including devices, backend, and identity infrastructure
  • Custom encrypted communication protocols - secure protocols for constrained embedded environments (BLE, USB, RS-232/485, WebSockets)
