IT infrastructure and network security
A secure wallet or AI tool starts with a secure foundation. With more than 20 years of experience in Microsoft environments, networks, servers and firewalls, I make sure that foundation is right.
What I do
- Network and Wi-Fi. I set up a well-designed network with separate segments for guests, devices and work, so one infected device can't reach everything.
- Firewalls. I help with configuration, rule clean-up and monitoring, so only what needs to be open is open.
- Servers and hardware. I advise on hardware and handle installation, updates, backups and recovery. I also test whether your backups actually work.
- Microsoft environments. I set up Microsoft 365 and Windows securely, with multi-factor authentication, managed devices and the right permissions.
- Linux web servers. I secure and maintain web servers and small websites.
Approach
I start with an inventory: what's there, who has access and what's critical. Then you get an overview of risks and improvements, ordered by impact. You decide what we tackle: once, as a project or as ongoing support.
What you get
- An overview of your IT environment and its main risks
- A stable, securely configured network
- One point of contact who understands both the basics and the new threats
Wondering what this means for you?
An introduction is free and without obligation. We discuss your situation and I tell you honestly whether and how I can help.
