Network defence
Firewalls, segmentation and traffic analysis: learning what normal looks like so the abnormal stands out.
Cybersecurity · Learning in public
Security skills.
Business fluency.
I'm at the start of my cybersecurity journey, learning through online courses and first experiments in virtual machines. I build on eight years of European B2B sales and operations. My goal: do the technical work and explain the risk to decision-makers in plain language, in Slovak, Hungarian or English.
What I'm working on
Five focus areas.
Ethical hacking & pentesting
Learning attacker techniques in isolated virtual machines to understand how systems actually break.
Cloud security
Identity, misconfiguration and logging in cloud platforms, where many real incidents start.
Identity & zero trust
Access control, MFA and least privilege: every request is untrusted until it is verified.
OSINT
Open-source intelligence: finding and verifying what is publicly visible about a company, its people and its infrastructure, and what an attacker could learn from it before they ever touch a system.
Why work with me
Business experience, technical curiosity.
Security in plain language
Eight years in client-facing European B2B work taught me to explain technical risk to people who make decisions, in Slovak, Hungarian or English.
Process discipline
I own a full order cycle end to end and test with Postman, Selenium and JMeter. Security is a process, and I'm used to running processes that can't fail quietly.
Builder mindset
Self-taught in Python, SQL and Linux. I learn by building, so each security topic will get its own lab and write-up as I go.
Certifications
Currently studying. Certifications will be listed here as I complete them.
