Domain · Security by design

Security decided at design time, not discovered in production.

We build security into your projects from the start: explicit requirements, threat modelling, architecture reviews and acceptance criteria checkable before release.

Situations

You are in the right place if…

  • Your applications’ flaws are found at the penetration test, just before release.
  • Your product teams start projects without written security requirements.
  • Nobody can say which threats a new architecture must counter.
  • You place a digital product on the market and must document its risk assessment.
  • Your CI/CD pipeline ships fast, but nothing in it checks security.
Our conviction

A flaw avoided at design time costs less than a flaw fixed in production.

Fixing a design flaw once the product has shipped often means reworking the architecture, migrating data, notifying clients. At design time, the same decision fits in one line of requirement.

So we build security into your teams’ existing rituals: a requirement in the ticket, a threat in the architecture diagram, a criterion in the definition of done, a control in the delivery pipeline.

Our approach

From requirement to acceptance criterion.

Light practices, built into your development cycle, rather than a parallel process.

  1. 01State the requirementsFor each project or feature: data processed, exposure, obligations, security requirements.

    You getWritten security requirements

  2. 02Model the threatsA short workshop with the team: what can go wrong, and what prevents it.

    You getAn up-to-date threat model

  3. 03Review the architectureAuthentication, segregation, encryption, logging, dependencies: reviewed before development.

    You getDocumented architecture decisions

  4. 04Set acceptanceCheckable criteria, tested in the delivery pipeline before release.

    You getAcceptance criteria and their controls

What the texts say

What the texts expect of design.

Several texts make security a design requirement, no longer just an operating one.

  • CRACRA art. 13(1) · CRA art. 13(2)

    The manufacturer of a product with digital elements designs and develops it in accordance with the essential cybersecurity requirements, and assesses its cybersecurity risks to take them into account from planning to maintenance.12

  • DORA · RTSRTS 2024/1774 art. 16(1) · RTS 2024/1774 art. 16(1), point (b) (ii)

    Financial entities adopt a policy governing the acquisition, development and maintenance of ICT systems, which identifies security requirements and has them approved by the business function and the asset owner.34

  • NIS 2NIS 2 art. 21(2), point (e)

    The directive lists security in the acquisition, development and maintenance of systems among the measures Member States must require of entities.5

  • GDPR · CNIL guideRGPD art. 25(1) · Guide CNIL sécurité, fiche 11, F11-PE-01

    The controller implements data protection by design; the CNIL recommends building security requirements into it, through choices of architecture, features and technologies.67

Our engagement

The same topic, at three levels of engagement.

You choose the level; the scope and deliverables are set by contract.

Level 01

Monitor

At agreed intervals, we check that projects go through the planned security steps and that delivery pipeline controls run.

Deliverables
  • Tracking of projects and their security steps
  • Check of acceptance criteria in CI/CD
  • Dashboard of gaps
Level 03

Drive

We embed the practices in your teams and track their adoption, without making the changes in your systems.

Deliverables
  • Integration into the team’s rituals and tools
  • Tracking of decisions and gaps
  • Evidence file for your clients and auditors
Accelerators

What we bring from day one.

Requirements catalogue

Reusable security requirements by project type, linked to the texts they serve.

Threat workshop format

A one-hour workshop, with its materials, to model a feature’s threats with the team.

Delivery pipeline controls

Checks to plug into your CI/CD so acceptance criteria are tested at every release.

Frequently asked questions

Before we start.

Does this slow our teams down?

Little, if the practices fit into existing rituals: a requirement in the ticket, a short workshop for sensitive features, an automatic control in the pipeline. The time comes back in fixes avoided.

Must every feature’s threats be modelled?

No: only features that touch sensitive data, authentication, payments or exposure. We help your teams spot them.

Does the CRA require a risk assessment?

Yes, for a manufacturer of a product with digital elements: it must be carried out and taken into account from planning to maintenance. Have the CRA’s applicability confirmed by your legal counsel or lawyer.2

Do you work with our agile methods?

Yes. We fit into your rituals (refinement, review, definition of done) rather than adding a process alongside.
