Work
I specialize in strengthening organizational defenses through the deployment and tuning of network IDS/IPS systems and the implementation of cloud-based security controls, enhancing visibility, detection, and prevention across modern infrastructures.
In my spare time, I conduct malware analysis to stay aligned with evolving attacker techniques and continuously refine my defensive mindset.
About me
Hi, I’m Áron Gellén, an IT security advisor with over 15 years of experience across cybersecurity, cloud security architecture, and enterprise infrastructure. I’ve had the opportunity to work with companies of all sizes—from global corporations to national enterprises—helping them secure their systems, protect sensitive data, and navigate today’s evolving cyber threats.
Over the years, I’ve held roles like Senior Cybersecurity Engineer, Security Analyst, and System Administrator, giving me end-to-end visibility of IT operations—from the ground-level architecture to high-level strategic planning. I’ve architected and implemented cloud security solutions, advised on regulatory compliance, and built security frameworks aligned with industry standards, including the NIS2 directive.
I support organizations in building resilient defenses through network IPS deployments, layered security controls, and robust protection mechanisms to detect, prevent, and respond to cyber threats.
