We accompanied them
After a complicated transition period, I needed to start afresh on solid foundations. The IT Systèmes team supported me with rare kindness. Everything was taken care of, from the Microsoft and Outlook migration to the implementation of a new infrastructure and a ready-to-use telephone system. Today, thanks to their outsourcing, I can finally focus on my business with complete peace of mind. The people I spoke to were attentive, responsive, and truly competent.
In an industrial context where service continuity is essential, we chose IT Systèmes to deploy Microsoft Defender for Endpoint and reinforce the supervision of our network. Their team ensured full integration of the solution with our existing infrastructure, notably via Microsoft 365 and Azure AD. In just a few weeks, we gained visibility over our endpoints, reduced vulnerabilities and automated incident management.
IT Systèmes supported us in implementing a comprehensive cybersecurity policy, from data encryption to secure backups on Microsoft 365. Their expertise has enabled us to raise our level of RGPD compliance while simplifying day-to-day IT management. The team is highly responsive and has a perfect understanding of the issues specific to the legal environment. Trusted support, both technical and human.
