About me
I’m Samir Brkic, founder of SamiXone Digital Solutions in Wuppertal. By day I secure networks and firewalls in enterprise environments as a Senior Cyber Security Engineer. I bring that knowledge to small businesses, practices, clubs and private customers – clearly explained and cleanly documented.

Story
Everything began with PCs: selling, building, upgrading, setting up, repairing. That taught me two things: how technology works on the inside – and how to listen to people who simply want it to work again.
Then came networks – and the question of how data gets safely from A to B. That question became my profession. Today I work as a Senior Cyber Security Engineer in network and firewall security, certified by Check Point as a Security Expert (CCSE) and Troubleshooting Expert (CCTE).
I also build software I use myself: Lernity, a vocabulary trainer with AI, and Vernity, club management software that runs in the club whose books I keep as a volunteer. Internally, I use SamiXone Sentinel every day – my own analyser for Check Point firewall policies. None of the three is a marketing project. They are tools.
SamiXone Digital Solutions brings this together: experience from enterprise environments, and a feel for the everyday reality of small businesses, practices, clubs and private customers. I work remotely or on site in Wuppertal, by arrangement. You always talk to me – and every change is documented well enough that someone else could follow it later.
Path
Not a CV – five stops where I learned what matters.
Selling, building, upgrading, setting up, repairing. This is where I learned to find the fault instead of swapping parts.
How data gets from A to B – and where it snags when it doesn't.
Network and firewall security in enterprise environments, today as a Senior Cyber Security Engineer. Check Point certified: CCSE and CCTE.
Lernity and Vernity are live; Sentinel runs internally in my daily work. I build what I need myself – and learn from it what maintainability means once software is in real use.
All of it for small businesses, practices, clubs and private customers. Remote or on site in Wuppertal – with me as your single point of contact.
Values
Three words that could be on any website. Here is what I mean by them.
Before I change anything, I tell you what I plan to do and why – in plain sentences. You get a recommendation you understand, and the decision stays yours.
Clean work instead of quick patches. I’d rather do things right once – and record every change so it can be traced later.
Backups, firewall and secure access are part of every job I take on, the small ones included. Security is my day job – and the standard I hold every piece of work to.
Beyond work
Neither is a side project: real users, real data, real responsibility.

Self-hosted
Privately, I run what I recommend to others – and learn from it what really counts in day-to-day operation: backups, updates, a clear overview.
First conversation
A short conversation is enough to see whether and how I can help. No obligation, no jargon.
