Spyregia ā€“ Safety & Cybersecurity for Embedded Systems
We secure what runs your world.

At Spyregia, we bring safety and security to life inside embedded systems.
Our work bridges deep firmware engineering with practical safety and cybersecurity expertise ā€” from first concept to field deployment.

1. Embedded Safety & Cybersecurity Audits

Your system under the microscope.
We analyze existing firmware and architectures for safety and security gaps ā€” fast, precise, and hands-on.

  • Vulnerability & threat assessment
  • Code & architecture review
  • Compliance mapping (IEC 62443, NIST CSF, ISO 26262, FDA)
  • Actionable findings with clear mitigation paths

šŸ’” Free if no issues found ā€“ pay only when we detect real risks.

2. Firmware Development & Modernization

From clean-sheet design to life extension.
We develop, port, and harden firmware for safety-critical applications.

  • Embedded software design in C, C++, and Rust
  • Migration of legacy systems to Rust for memory safety
  • Bootloader and OTA update frameworks
  • Secure Boot, authentication, and cryptography integration

3. Security Architecture & Concept Design

Security starts with structure.
We help you design systems that are secure by design ā€” not by accident.

  • Threat modeling and risk analysis
  • Secure development lifecycle (SDLC)
  • NIST CSF 2.0 and IEC 62443 alignment
  • FDA Cybersecurity Guideline support

Our focus: practical security that fits your product, not paperwork.

4. Functional Safety Consulting

We make standards usable.
Support for ISO 26262 (Automotive) and IEC 62304 (Medical) without the bureaucracy overload.

  • Safety case review and documentation
  • Traceability and verification planning
  • Risk and hazard analysis
  • Tailored processes for small and mid-sized teams

5. Secure OTA & Lifecycle Solutions

Long-term reliability meets modern update strategies.

  • Robust OTA architecture and bootloaders
  • Delta and rollback management
  • Cryptographic signing and key handling
  • Lifecycle support from prototype to production

Because products evolve ā€” safety must follow.

6. Training & Knowledge Transfer

We build teams that build securely.

  • Rust for Embedded Safety
  • Cybersecurity for Firmware Engineers
  • IEC 62443 / NIST CSF fundamentals
  • Secure coding mindset and review practice

Hands-on workshops, no slideshows.
