Programme - 57 days / ~3 months
A continuous, progressive path designed to take you from technical foundations through to a complete professional project presented before a panel. Each block builds on the previous one; the day-by-day detail of every module (objectives, content, assessment) is provided when the programme begins.
Partir sur des bases solides et cadrer le projet professionnel.
Comprendre les grands enjeux de la cybersécurité, de l'intelligence artificielle et de la donnée.
Sécuriser les systèmes, puis détecter et réagir.
Penser comme un attaquant pour mieux défendre, et caractériser une compromission.
Passer de la technique à la gouvernance de la sécurité.
Constituer le dossier et se préparer au jury.
A new professional life.
Job-ready, prepared to validate competency block BC03 of the level 7 RNCP38823 qualification, and supported into employment.
The KLE Formations difference: training built around practice
A running project throughout the programme, from the very first modules, lets you both absorb what you learn in class and gradually build a complete project inspired by a real business challenge.
It is this progressively built project that forms the basis of the final defence before the jury.
The running project in practice
A single company case study runs through the whole programme.
- A real business problem to analyse from the very first modules
- A deliverable at every stage: architecture, hardening, detection, auditing…
- A project that grows step by step with the skills you acquire
- A final defence to demonstrate mastery of the whole programme
What you build
Each phase adds a new stone to the project, up to its final validation.
Support and follow-up after the programme
Far more than a training provider: individual follow-up for 1 to 6 months to embed your learning and consolidate your skills within the company.
Our commitment to quality
A quality commitment recognised by Qualiopi certification, compliant with the French National Quality Framework.

Funding
Retraining or upskilling has a cost - but rarely one you bear alone. Several schemes can step in and, in most cases, they can be combined.
The principle: your status determines your entitlements
No funding is automatic. The right scheme depends above all on your situation (employee, jobseeker, self-employed, public sector worker). Most can be combined and cover the bulk of the cost.
Good news if you’re moving into these professions: KLE Formations programmes tick the right boxes.
Our cybersecurity programmes aim for a level 7 RNCP qualification and our organisation is Qualiopi-certified, which makes them eligible for all funding schemes: CPF, France Travail (AIF, POEI), OPCO, Transitions Pro.
Our AI and data programmes follow the same logic.

Frequently asked questions
These programmes are designed for people holding a bachelor's degree, or with at least two years of professional experience in the field, who want to move into cybersecurity roles. Training alternates targeted theory, guided labs, realistic scenarios and team exercises, to build genuine professional reflexes. An alternative admission route exists for applicants who do not meet these conditions: entrance tests, a cover letter and a selection interview.
A technical foundation is required. The programme starts with fundamentals in networking, Linux and cloud, but it consolidates them rather than teaching them from scratch. The positioning test checks that foundation before training begins.
The programme is designed for employability (professional project, capstone, targeted career opportunities), but no job can be guaranteed: the outcome depends on your attendance, your progress and the state of the market. Our teams support you in your job search.
Get in touch describing your background and your situation (CPF, France Travail, OPCO, Transitions Pro…). An adviser will check your eligibility and work out your remaining cost with you, subject to conditions.
