Ship embedded Linux products that meet the Cyber Resilience Act.

Independent security and compliance consulting for manufacturers of Linux-based devices. I build the threat analysis, the SBOM and the technical documentation, and I design the security features that make them true.

I help manufacturers of connected products turn the EU Cyber Resilience Act (CRA) into a competitive advantage.

With 40 years in embedded systems, 25 years in cryptography, and 15 years in automotive product security, I cover the full stack: threat & risk assessment, security architecture, secure boot, HSM, ARM TrustZone, Linux hardening, and supplier security.

The result: products that are not just compliant, but demonstrably more secure than the competition.

Security is now a condition of selling in the EU.

The Cyber Resilience Act (Regulation (EU) 2024/2847) makes cybersecurity a requirement for CE marking of products with digital elements. Manufacturers carry the responsibility for the whole product lifecycle, including third-party components such as the Linux kernel, bootloader and open source libraries.

Dates as published in the regulation. Confirm applicability to your product category before planning.

Official sources

10 December 2024

The CRA entered into force.

11 September 2026

Reporting obligations apply. Manufacturers must notify actively exploited vulnerabilities and severe incidents within tight deadlines, starting with an early warning within 24 hours. Notifications go through ENISA’s Single Reporting Platform. Read the Commission’s reporting rules.

11 December 2027

Main obligations apply. Products placed on the EU market need security by design, a vulnerability handling process, an SBOM and complete technical documentation.

Engineering support from threat model to technical file.

Practical work products your team can build on, written by someone who has shipped the underlying hardware and software.

CRA readiness and gap analysis

A clear view of where your product and processes stand against the essential requirements.

  • Product classification and scope
  • Supplier and component security
  • Gap report with prioritised actions
  • Conformity route and CE documentation

Reference: Commission CRA guidance and FAQs.

TARA

Threat analysis and risk assessment that engineers can implement and auditors can follow.

  • Assets, attack paths and risk rating
  • Security goals and treatment decisions
  • Traceability to requirements and tests

SBOM and vulnerability handling

A software bill of materials wired into your build, plus the process to act on what it shows.

  • SPDX or CycloneDX from Yocto, Buildroot or Debian builds
  • CVE monitoring and triage workflow
  • Coordinated disclosure and update policy

Formats: SPDX, CycloneDX. Reference: CRA reporting rules.

Security architecture

Security features designed for your hardware, your constraints and your update model.

  • Secure boot and chain of trust
  • Key management, HSM and hardware roots of trust
  • ARM TrustZone, secure OTA updates, Linux hardening

Technical documentation

The evidence a market surveillance authority or notified body expects to see.

  • Risk assessment and security requirements
  • Design and test evidence
  • Support and update lifecycle records

Reference: CRA legal text and summary.

Cryptography review

Independent review of algorithm choices, protocols and key handling in hardware and software.

  • Protocol and library selection
  • Key lifecycle and provisioning
  • Post-quantum migration planning

A working method that fits a small team.

You do not need a security department. You need the right decisions made early and documented as you go.

  1. Scope

    We define the product, its intended use and the applicable requirements in a short call.

  2. Analyse

    Threat model, SBOM baseline and gap analysis show what must change and what already holds up.

  3. Design

    Security features are specified and reviewed with your engineers against real hardware limits.

  4. Document

    Evidence is produced alongside the work, so the technical file is ready when you are.

  5. Sustain

    Vulnerability monitoring and update processes keep the product compliant after launch.

Information Security Analyst & Evangelist

I have built embedded Linux systems from the hardware up, and I have worked on cryptography where it is hardest to get right: in silicon, in firmware and in vehicles. That background lets me talk with your developers about boot flows and key storage, and with your management about risk and deadlines.

Automotive cybersecurity taught me what a rigorous, auditable security process looks like. I bring that discipline to your product, scaled to your company.

30years in embedded Linux, hardware and software
25years in cryptography, hardware and software
15years in automotive cybersecurity

Start with a conversation about your product.

Tell me what you build and where it is sold. You will get an honest view of what CRA compliance means for you and a proposal for the next step.
