Oleksandr is an engineering leader with 15+ years of building and scaling teams at companies of all sizes. He co-created LLM Guard, an open-source LLM firewall with over 12 million downloads, along with the security models that power it. LLM Guard is used by security teams worldwide to protect AI applications in production. After Laiyer AI was acquired by Protect AI, which was later acquired by Palo Alto Networks, Oleksandr led agent security efforts there. That work gave him a front-row seat to the challenges enterprises face as they deploy autonomous AI systems at scale. Now, together with Neal Swaelens, he has set his sights on securing the next frontier: autonomous agents running on every endpoint in the enterprise.
