Cybersécurité pragmatique pour TPE, PME et ETI avec un RSSI externalisé

An abstract yet concrete representation of a secure small business network: a compact black server box and several labeled network switches neatly mounted in a small wall cabinet, with tidy blue and white Ethernet cables carefully organized in cable guides. A printed, color-coded network diagram is pinned on the adjacent wall, showing simple icons for workstations, cloud, and firewall. The environment is a modest but clean SME back-office with white walls and a matte grey floor. Cool, diffused ceiling lighting eliminates harsh shadows, giving the scene a controlled, organized feeling. Photographic realism, slightly elevated angle, with sharp focus throughout, communicates clarity, simplicity, and practical cybersecurity tailored for TPE and PME.
A sleek, modern cybersecurity command center table featuring an open silver laptop displaying a clean dashboard of green checkmarks, security shields, and simple graphs. Beside it, a neatly stacked folder labeled “RGPD • NIS 2 • ISO 27001” rests on a light oak desk, alongside a secure hardware key and a closed, branded notebook. The scene is set in a bright, minimalist office with neutral walls and a blurred cityscape visible through a large window. Soft daylight creates gentle reflections on the laptop screen and subtle shadows across the desk. Shot at eye level with photographic realism, using a shallow depth of field so the background gently fades, reinforcing a calm, trustworthy, professional mood with a clean, accessible aesthetic.

Qui je suis, d’où je viens

Ancien responsable cybersécurité en groupe international, j’ai créé mon activité de RSSI externalisé pour rendre la sécurité accessible aux dirigeants. J’interviens à temps partagé, avec une approche terrain, orientée résultats et conformité (RGPD, NIS 2, ISO 27001).

Une méthode claire pour vous protéger

Chaque mission commence par un audit adapté à votre taille, suivi d’une feuille de route priorisée et chiffrée. Nous déployons ensuite les actions ensemble, avec un suivi régulier pour mesurer les progrès et ajuster la protection.

Bruno a transformé notre approche de la cybersécurité : audit clair, plan d’actions priorisé et suivi mensuel. Enfin un expert qui parle le langage d’une PME industrielle.

En quelques semaines, nous avons sécurisé nos accès, mis à jour nos procédures RGPD et formé les équipes. Le tout sans bloquer l’activité. Un accompagnement vrai, pragmatique.

Nous n’avions ni RSSI ni service IT structuré. Bruno a posé un cadre simple, priorisé les risques et nous a préparés sereinement à NIS 2.

Lors de notre incident de rançongiciel, Bruno a coordonné la réponse, parlé avec l’assureur et rassuré la direction. Son expérience terrain a clairement limité l’impact financier.
