OSAbout Oleksandr
I’m a CISO-level cybersecurity leader and hands-on architect who has climbed every rung of the security ladder - Researcher → Consultant → Engineer → Architect → CISO. That 360° journey lets me see a threat landscape from boardroom to kernel space and speak fluently with executives, developers, and red-teamers alike.
As the Co-Founder and CISO of CyberTide, I am channeling this comprehensive experience into pioneering next-generation Data Security systems. My focus is on the critical intersection of AI and cybersecurity - not only leveraging AI to build smarter security solutions but also architecting defenses to secure the AI systems themselves against emerging threats.
