Matthieu R.

With over 25 years of experience in Information Systems, I've evolved from application development to IT Manager and Chief Information Officer (CIO) roles. Now specializing in cybersecurity, I assist companies (SMEs, mid-caps, large accounts) with a unique dual approach: a strategic vision (aligned with your business objectives) and end-to-end technical mastery.

My goal is not just to solve a technical problem, but to design a robust, secure, and sustainable solution, adapted to your budget and your users.

- Security audits and risk analysis

- Implementation of security policies (PSSI)

- Securing architectures and guidance on best practices

- Network architecture, routing, Wi-Fi

- Deployment and management of Firewalls & VPNs

- Telephony & VoIP: 3CX Advanced Engineer Certified

- Windows and Linux server administration

- Virtualized environments: Hyper-V, VMware, Proxmox

- Private and hybrid cloud

- Management of complex projects (server migration, IT relocation, network redesign...)

- User support and training

- Liaison between senior management and technical providers

Pragmatism: Concrete solutions, without unnecessary jargon.

Serenity: You entrust your IT to a senior profile.

Tailor-made: I intervene from the audit phase to skills transfer.
