🤖 Did you notice this picture was retouched with AI? The face is real (a holiday photo), so is the T-shirt… the workshop, however, is a bit tidier than the real one. Spotting this kind of fake is precisely part of my job: phishing, cloned voices and deepfakes.
Your trusted IT specialist, since 2001
My name is Daniel Platteau and I have been running ExsIT since 2001. In 2022, I was planning to retire… but my clients kept calling me. And since IT has never moved this fast — artificial intelligence is revolutionising the field — I decided to carry on. With the same enthusiasm, and twenty-five years of field experience on top.
Individuals, freelancers and SMEs: I support you remotely or on-site in the Charleroi area — and now also in adopting AI, without jargon or empty promises.
My services
🖥️ IT support
Troubleshooting, preventive and corrective maintenance, remote or on-site assistance. Software installation, system security, updates and performance optimisation. I support individuals, freelancers and SMEs with all their day-to-day IT needs.
💻 Hardware supply
Need a new computer, a reliable network or a server? I select, deliver and install hardware tailored to your budget and requirements — without selling you what you don't need.
🔐 Security & advice
Data backup, antivirus protection, secure network configuration and digital best-practice guidance. Because a breakdown or an attack doesn't warn you, prevention is always better than cure.
🤖 Artificial intelligence for SMEs
Identifying the tasks where AI really saves time, choosing GDPR-compatible tools, training your teams and keeping your data under control — including with an AI installed on your own premises, without the cloud. Start with my AI articles.
Practical guides & tips
💾 Protecting your data: the complete guide — hardware failure, ransomware, human error: your data is more fragile than you think. The 3-2-1 rule, the right tools (Macrium Reflect, MailStore Home, Synology NAS) and a concrete strategy so you can sleep soundly.
Why choose ExsIT?
- ✅ Responsiveness — fast intervention, remotely or on-site in the Charleroi area. You talk directly to the person who does the work, not to a ticket.
- ✅ Transparency — clear quotes, no nasty surprises. I explain what I do and why: you stay in control of your decisions.
- ✅ Independence — tied to no brand. I recommend the hardware that fits your needs, and you choose where to buy it: from me with a clear quote, or yourself (some Amazon links are affiliate links, always marked).
