Platanor Technologies
Security-first embedded systems for IoT and connected devices.
We help companies build secure embedded and IoT devices - from security architecture to production deployment.
This includes provisioning, attestation, authentication, and secure communication.
Built to meet modern cybersecurity requirements such as the Cyber Resilience Act (CRA).
For device manufacturers, IoT companies, and hardware startups building connected products.
Production hardware experience • security-focused architecture • senior embedded engineers
What We Do
We design and implement embedded security architecture for connected and IoT devices - including device identity, device provisioning, authentication, and secure communication.
From first prototype to production deployment.
Security & Compliance Challenges addressed: Gap between regulatory requirements (CRA) and actual system design.

Typical Security Architecture
A secure connected device follows a layered trust model across its lifecycle:
Hardware root of trust
Secure boot
Secure provisioning (manufacturing)
Device identity & attestation
Authentication & secure communication
Secure firmware updates & lifecycle control
Together, these layers ensure device authenticity, secure firmware integrity, OTA update safety, and trusted communication.
Why Platanor
Security-first architecture
Security is designed as a core system property - not added later. We design device identity, provisioning, authentication, and secure communication as fundamental architectural elements.
Deep embedded expertise
Our work happens close to the hardware: firmware, RTOS-based systems, communication protocols, and device-level security mechanisms.
Senior engineers only
You work directly with senior engineers - no outsourcing layers.
Production-ready mindset
We design systems for the entire lifecycle of a device - from development and manufacturing to provisioning, deployment, and long-term operation.
Regulatory-driven reality
Modern regulations such as the Cyber Resilience Act (CRA) require manufacturers to implement proper device security. We translate these requirements into concrete engineering decisions and production-ready systems.
When Clients Typically Contact Us
Companies typically engage us when:
- A new connected device needs security architecture from the start
- Security must be added to an existing embedded system
- A secure provisioning process is required for manufacturing
- Backend systems must reliably verify device authenticity
This usually occurs between early prototyping and preparation for manufacturing.
Where Security Mistakes Usually Happen
Most security issues originate from early architectural decisions - not from implementation details.
Common patterns we see:
No strong device identity from the start
Missing or weak provisioning process during manufacturing
Secrets stored in firmware or accessible via debug interfaces
No secure update mechanism
Security added late as ad-hoc encryption
These decisions may seem acceptable during prototyping, but become extremely costly to fix once devices are deployed at scale.
Security & Compliance Challenges
- Lack of internal expertise to implement device security correctly
- Gap between regulatory requirements (CRA) and actual system design
- Security added too late in the development process (leading to costly redesigns)
- No clear path from prototype to production-ready secure system
- Insecure or ad-hoc communication protocols
Manufacturing & Provisioning
Secure device provisioning is a critical part of any production IoT system.
We design:
This ensures every device is uniquely identifiable and trusted in production environments.
This is where many systems fail - and where production security is actually established.
Our Approach
Security must be designed into the system from the beginning - it cannot be reliably added later.
Our work starts with a device threat model tailored to embedded and IoT security risks. We identify realistic attack vectors such as firmware extraction, device cloning, debug access, and backend impersonation, and design security mechanisms to mitigate these risks.
Once devices are manufactured and deployed, introducing proper security becomes extremely difficult and often impossible. Early decisions - device identity, secure boot, key storage, and provisioning - determine whether the system can remain secure in production.
Designing security from day one ensures a trustworthy foundation across the entire device lifecycle.
Consequences of Poor Device Security
Weak embedded and IoT device security leads to real operational and business risks:
- Device impersonation and unauthorized access
- Firmware tampering and loss of control over devices
- Extraction of secrets and compromise of backend systems
- Inability to revoke or update compromised devices
- Costly recalls or forced hardware revisions
These risks are extremely difficult and expensive to address after deployment.
Security Is Not Only for “Security Devices”
Even seemingly simple connected or IoT devices (e.g., smart home appliances) can introduce serious risks if security is not designed properly.
Such devices often:
- Connect to local or corporate networks
- Store credentials and interact with cloud services
- Communicate with other systems inside the local network
- Include sensors or interfaces that can be misused
Without secure boot, provisioning, and device attestation, there is no guarantee that the device runs authentic firmware or that it is a genuine product.
Regulations such as the Cyber Resilience Act (CRA) were introduced in response to these real risks - many of which are still underestimated or overlooked in device development.
Security is therefore not optional - it is a fundamental requirement for any connected device.
One Team - Full Stack
Hardware, firmware, device software, and backend integration are designed together.
This avoids the common problem of fragmented development across multiple vendors.
CRA Compliance Deadline: December 11, 2027
If you build connected devices for the EU market, CRA compliance is not optional — and the deadline is closer than you think. We help device manufacturers become compliant before it's too late.
