About Nicolas

For 15 years, I have designed and operated the system and cybersecurity architecture of a national group with 200,000 employees and volunteers: 400 servers, nomadic MDM for 57,000 terminals, HDS / CNIL / ANSSI compliance built-in. Today, I am applying this rigor to French SMEs and ETIs through ARCHICORP-IT.

FOUR PREMIUM EXPERTISE AREAS

Proactive Managed Services — Continuous monitoring, updates, tested backups, dedicated helpdesk. Measured availability 99.93%. GTI 2h, GTR 4h.

Managed Cybersecurity — EDR/MDR, SOC, managed firewall, MFA, awareness training, DRP. ANSSI / EBIOS RM methodology. Referenced on cybermalveillance.gouv.fr.

Outsourced CIO — IT strategy, technology roadmap, board reporting. Part-time IT management for organizations with large enterprise challenges but without the critical mass.

Audit & Compliance — Technical, organizational, and documentary audits. Compliance with NIS2, GDPR, HDS. Defensible proof files.

TARGET AUDIENCE

Leaders and IT managers of growing SMEs and ETIs · Multi-site or multi-country organizations · Sectors subject to NIS2, strict GDPR, cyber insurance, or HDS · Overwhelmed or transforming IT departments.

MY CONVICTION

All companies have the capacity to grow with IT. The right tools exist — they just need to be selected, deployed, and operated over time with the rigor of large corporations and the flexibility of an independent partner.

WHAT MY CLIENTS SAY

"He is involved in strategic as well as operational aspects." "He understands leaders as well as technicians." "He has a rare ability to identify blocking points and find solutions to overcome them." "He forces us to ask the right questions for the future."

WHAT DIFFERENTIATES ME

A single technical contact from quote to delivery. No offshore subcontracting. Regulated large enterprise expertise adapted to your scale. Not a salesperson, but an architect.

    CYBERSECURITY AUDIT FOR DEVELOPMENT TOOLS MIGRATION
    Audit mission commissioned by the cybersecurity department of Swisslife assurance as part of the project to migrate development environments from VirtualBox to WSL 2. Scope: approximately 60 developers. Cross-functional assessment of organizational, technical, and financial risks.

    CONTEXT AND CHALLENGES
    VirtualBox historically equipped teams to run Linux environments on Windows machines. The migration to WSL 2, integrated into the Windows kernel, raises security, isolation, performance, and compliance issues that the CISO wants clarified before budget and operational decisions.

    TECHNICAL RISKS
    Comparative study: isolation model (Type 2 hypervisor vs. kernel-integrated subsystem), attack surface, threat exposure, secrets management, host filesystem interactions, EDR / antivirus compatibility, monitoring capabilities, compliance with ANSSI and CIS hardening standards.

    ORGANIZATIONAL RISKS
    Impact on teams: developer learning curve, support processes, image and template governance, integration into CI/CD pipelines, change management and necessary acculturation for adoption.

    FINANCIAL RISKS
    3-year comparative TCO modeling: licenses (VirtualBox Extension Pack, Windows, Microsoft 365), indirect costs (productivity, support, training), potential remediation costs. Identification of economic arbitration levers.

    DELIVERABLES AND RECOMMENDATIONS
    Structured report: weighted risk matrix, detailed technical comparison, quantified financial analysis, recommendations for the CISO and CIO. Transition scenarios (big bang, phased, pilot) presented to the relevant departments.

    ARCHICORP-IT'S APPROACH
    Strategic decision audit: model risks transversally (technical and organizational) and deliver actionable recommendations for a cybersecurity department.
