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 Malakoff (92), 15 minutes from downtown Paris. A critical incident at a client’s site in Paris’s 15th 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 industrial SMEs in Saint-Denis: for the past 15 years, 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.”

Background: 80 employees, manufacturing of aerospace parts, fragmented IT system (5 business software applications that do not communicate with each other).
Solution: Integration of the five software applications via iPaaS (FlexFlow), Intune for device management, and a phased migration to a hybrid Azure architecture.
Results: 60% reduction in redundant data entry time. NIS2-compliant remote access. Stable IT costs despite an increase of 15 employees.
IT outsourcing rates for a Paris-based SME vary depending on the scope of services: a support flat rate of 25–40 EUR per workstation per month for basic services (help desk + maintenance), and 60–100 EUR per workstation per month for a comprehensive MSP package that includes proactive monitoring, managed SOC, advanced security, and strategic consulting. For one-time needs (audits, migration projects, compliance), we work on a project-based flat-rate basis, with a quote provided within 48 hours following a free audit.
For our clients with managed services contracts, our teams arrive on-site in less than 4 hours on average within Paris and the surrounding municipalities (Malakoff, Boulogne, Issy-les-Moulineaux, Vanves, Montrouge). Our remote support team is available 5 days a week from 9:00 a.m. to 6:30 p.m. (with 24/7 on-call support available upon request). For new clients, we provide a quote within 48 hours and begin service within 1 to 4 weeks, depending on the size of the IT infrastructure.
IT maintenance is limited to equipment upkeep and incident resolution (when things break). IT outsourcing—or, more precisely, managed services (MSP)—covers a much broader scope: proactive monitoring 7 days a week, advanced cybersecurity, access management, backup, GDPR/NIS2 compliance, and strategic support. Modern IT outsourcing anticipates problems rather than simply fixing them.

We also cover all municipalities in the Hauts-de-Seine department (92) and provide project-based services in other departments of the Île-de-France region (78, 91, 93, 94).

For industry-specific software tailored to your sector, we also offer custom development (our “hyperdevelopment” service).
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.
Yes, we exclusively offer solutions hosted in France or within the European Union (Microsoft 365 data center in France, Azure EU, OVH, Scaleway).

For organizations with fewer than 10 employees, we recommend solutions better suited to your size.
Our standard support team is available from 9:00 a.m. to 6:30 p.m., Monday through Friday. For critical or multi-site environments, we offer an on-call service or 24/7 support (HNO — Outside Regular Business Hours) that can be activated as an option.
