Kis Ruben

At Bevel Security, I lead cybersecurity technology and threat intelligence operations, deploying vendor-independent Wazuh SIEM architectures and turning high-fidelity security events into actionable investigations.

I've architected ransomware-resilient decentralized backup systems using hardened IPFS, Rclone, and Zero-Access encryption. I also lead Pocket CISO, using locally hosted LLMs to help SMEs automate compliance, strengthen internal detection, and protect data privacy.

In national security and critical-infrastructure environments, I investigated cyber-espionage campaigns affecting election integrity, tracked state-sponsored APT activity, and worked with police and intelligence services on major breach investigations. My work spans incident response, purple teaming, CTI, threat hunting, SIEM/XDR, PAM, and regulatory advisory for NIS2 and the EU AI Act.

I've also secured medical IT infrastructure, mentored technical teams, built CTF challenges, and delivered training on SOC operations, secure coding, social engineering, WordPress hardening, and digital safety. I enjoy developing the next generation of cyber-defense talent through practical learning and community education.
