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 just a few weeks, we gained visibility over our endpoints, reduced vulnerabilities and automated incident management.

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.
