Since 2010, IT Systèmes has been helping small and medium-sized businesses and mid-market companies protect their information systems through audits, workstation and network security, SOC monitoring, and compliance with GDPR, NIS2, and DORA. A single point of contact, from initial assessment to ongoing monitoring.
Recruiting and maintaining an in-house IT security team (security architect, SOC analyst, compliance expert) rarely fits within the budget of an SME or mid-sized company. A service provider pools these skills and monitoring tools across multiple clients, making protection accessible without compromising on the standards expected by your partners, insurers, or clients during a request for proposals.
It's also a matter of continuity: threats don't adhere to business hours, and maintaining round-the-clock monitoring and supervision requires a dedicated organization—one that few companies can manage on their own.

An audit is a one-time assessment that provides an overview of the current situation and outlines an action plan. As a service provider, our support includes implementing these actions and monitoring them over time: protecting workstations and the network, providing oversight, and updating systems to address new threats.
SMEs and mid-sized companies are frequent targets, in part because they often have fewer safeguards than large companies. A service provider offers access to expertise and oversight that few SMEs can afford to fund in-house.
It depends on the scope and initial maturity of the information system. The initial audit helps establish a realistic timeline, with the most urgent actions addressed first.
