Since 2010, IT Systèmes has been supporting Paris-based small and medium-sized businesses and mid-market companies with their IT outsourcing, cybersecurity, and digital transformation. Our teams serve clients throughout Paris, the Hauts-de-Seine department, and the Île-de-France region.
Choosing a local IT service provider radically changes your relationship with IT. Quick response times, knowledge of the local business community, a designated point of contact, and GDPR compliance: these are the four concrete benefits for your small business.
Our teams are based in the Île-de-France region, just a few minutes from downtown Paris. A critical incident at a client’s site in Paris’s 8th, 15th, or 16th arrondissement is resolved in less than 4 hours on average, compared to 24–48 hours for national service providers.
Law firms in Paris's 16th arrondissement, accounting firms in Boulogne, and small and medium-sized industrial companies in Saint-Denis: since 2010, we have been supporting the diverse Parisian business community.

“After a difficult transition period, I needed to start over on a solid foundation. The team at IT Systèmes supported me. They took care of everything, from the Microsoft migration to setting up a phone system. Now I can finally focus on my business.”
"In an industrial setting where service continuity is essential, we chose IT Systèmes to deploy Microsoft Defender for Endpoint and strengthen the monitoring of our IT infrastructure. In just a few weeks, we gained greater visibility into our workstations, reduced vulnerabilities, and automated incident management."
“IT Systèmes has been providing us with managed IT services for over five years: responsive support, teams just five minutes away, Microsoft 365 security, and cloud backups. They now have a real understanding of our business needs. We’ve just entrusted them with the development of our custom CRM as well, with delivery scheduled in 30 days.”

In day-to-day operations, a Paris-based small business needs us to pick up the phone quickly and resolve the issue without spending the whole day on it. Our IT support covers user assistance, preventive maintenance of your workstations and servers, and on-site service when a visit is necessary. Our teams are based in the Île-de-France region, which allows us to provide on-site service in Paris and the surrounding suburbs with an average response time of less than 4 hours. We also provide remote support throughout France.
For an SME, this support service includes a help desk that can be reached by phone, email, and through a web portal, handling requests from Level 1 to Level 3. Maintenance isn’t limited to troubleshooting: security updates, backup monitoring, and tracking the status of your IT infrastructure help prevent outages before they occur.
We can enhance your support system with Helpy, our AI-powered help desk: it instantly handles some of the most common requests (60% of Level 1 tickets), so you can get help faster every day. To learn more, contact us.

Paris is one of our four locations in France. To view our nationwide offerings and our other offices: IT service provider for small and medium-sized businesses
Our managed services rates depend on the scope of the service: a basic support package (help desk + maintenance) and a comprehensive MSP package (proactive monitoring, advanced security, strategic guidance). For one-time needs (audits, migration projects, compliance), we offer fixed-price project rates. In all cases, we provide a customized quote within 48 hours after assessing your needs.
Pour nos clients en contrat d'infogérance, nos équipes interviennent sur site en moins de 4h en moyenne sur Paris intra-muros (Paris 8e, 9e, 15e, 16e, 17e) et les communes limitrophes (Boulogne-Billancourt, Levallois-Perret, Neuilly-sur-Seine, Issy-les-Moulineaux, La Défense). Helpy, notre agent IA, répond 24 h/24 et 7 j/7 ; l'équipe humaine est disponible de 8 h à 19 h. Pour les nouveaux clients, devis sous 48h et démarrage de prestation sous 1 à 4 semaines selon la taille du parc.
La maintenance informatique se limite à l'entretien du parc et à la résolution d'incidents (quand ça casse). L'infogérance, ou plus précisément les services managés (MSP), couvre un périmètre beaucoup plus large : supervision proactive, cybersécurité avancée, gestion des accès, sauvegarde, conformité RGPD/NIS2, accompagnement stratégique. L'infogérance moderne anticipe les problèmes au lieu de simplement les réparer.

Our transition process takes place over 8 weeks: scoping and audit (S1-S2), training and skills transfer from your outgoing service provider (S3-S4), supervised shadowing (S5-S6), pilot phase followed by production (S7-S8). Your outgoing service provider has a contractual obligation to provide access and technical documentation (reversibility clause). We manage the transition for you, so you can continue your business as usual.
