Hi, I'm David Knichel

I hold a PhD (Dr.-Ing.) in hardware security and applied cryptography. I help you turn engineering knowledge into evidence for Cyber Resilience Act conformity.
DK

I turn your existing architecture, security controls and engineering documentation into a structured Cyber Resilience Act (CRA) evidence package.

Start with a €950 Scope Assessment · see pricing

What your evidence package contains

A structured repository connecting your product, its security decisions and the evidence behind them.

Requirement-to-evidence mapping
See which CRA requirements apply, how they are addressed, and where the supporting evidence lives.
Cybersecurity risk assessment
A product-specific assessment covering intended purpose, foreseeable use, attack scenarios, mitigations and residual risks.
SBOM & component assurance
A machine-readable software bill of materials (SBOM), with security-relevant dependencies, assumptions and third-party due diligence.
Product & architecture evidence
Clear documentation of the product boundary, interfaces, software and hardware components, remote data processing and external dependencies.
Vulnerability & lifecycle procedures
Documented processes for vulnerability intake, remediation, coordinated disclosure, CRA reporting, security updates and ongoing security review.
Evidence gap register
Anything that cannot yet be demonstrated is made explicit, together with the concrete engineering or documentation action needed to close the gap.

From a security decision to its evidence

Illustrative excerpt · not a client assessment

Security objective
Only authentic firmware updates should be installed.
Product implementation
The device verifies a signed update before installation.
Supporting evidence
Update architecture, signing-key procedure and signature-verification test results.
Open gap and next action
Evidence for rejecting a tampered update is missing. Run the negative test and attach its result.

Documentation records the engineering work; it does not replace it. If testing or a design change is needed, I identify and scope the gap and organize the resulting evidence. Additional engineering work is agreed separately.

Know the scope, cost and deliverables upfront

No hourly consulting project. Each engagement starts with a defined product, defined deliverables and a fixed scope.

CRA Evidence Package

From €2,900

For manufacturers preparing the evidence needed to demonstrate CRA conformity for one product or product family.

Includes:
  • Product and architecture documentation
  • Cybersecurity risk assessment
  • CRA requirements-to-evidence mapping
  • SBOM and component assurance
  • Third-party dependency assessment
  • Vulnerability and update processes
  • Support-period justification
  • Security verification evidence structure
  • Technical documentation
  • Prioritized evidence and engineering gaps

Fixed scope and price agreed after the Scope Assessment.

Discuss your evidence package

Why “from €2,900”?

Product complexity varies significantly. A single embedded device with a small software stack is fundamentally different from a product family with multiple applications, cloud components and external dependencies. The Scope Assessment establishes the boundary before any larger engagement begins.

A simple, low-overhead process

Remote and asynchronous by default, with clear points for your team's input.

1

Share what already exists

Share your existing product, architecture and security documentation. There is no need to prepare a compliance package first.

2

I assess the product and identify the gaps

I review the product boundary and existing evidence, then identify missing documentation and any technical work needed.

3

We close the evidence gaps

I build the documentation from your existing material. Your team receives prioritized actions where engineering input or testing is needed.

4

You receive a maintainable CRA evidence package

I hand over a structured repository linking requirements, assessments and supporting evidence, ready for your team to maintain as the product evolves.

  • Remote
  • Asynchronous by default
  • Fixed scope
  • Clear deliverables

Your sensitive product information stays protected

  • NDA before sharing technical information

    Use your NDA or mine.

  • Minimum necessary access

    Repository access is preferred where practical, but not required. Only the information needed for the assessment is requested.

  • Work in your environment when needed

    Sensitive documentation and source code can remain in customer-controlled systems.

  • No unapproved third-party processing

    Customer IP is not submitted to external AI or other third-party services without explicit approval.

You keep control of your IP, repositories and sensitive engineering data throughout the engagement.

Who you are working with

The same three threads run through every role: designing security architecture, meeting regulatory requirements, and writing the documentation that demonstrates both.

Tell me about your product

Send a short description of your product, its development stage and where you need help. Keep the first message non-sensitive; we can arrange an NDA before sharing technical details.

We agree the scope and required inputs before work begins. An enquiry does not commit you to an assessment.
