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.
AI revolutionizes software development: why investing fortunes in standardized solutions no longer makes sense
Why pay €225,000 for standardized software when you can have it tailor-made for €99,000? Generative AI has just exploded the business model of software publishers. In 2025, developing a CRM or ERP perfectly adapted to your company will cost 3 times less than buying a standardized solution of which you will only use 30% of the functionalities. If you're about to renew your Salesforce, SAP or Odoo licenses, read this before you sign.

Spécial Cybersécurité Avocats - Post-mortem analysis of a preventable attack
A simple click. And everything changed. They thought they were "too small to interest a hacker". Within hours, their law firm was paralyzed: files encrypted, e-mails blocked, clients lost, reputation destroyed. It wasn't the attack that brought them down... It was the lack of preparation.
