From the frontlines of cybersecurity to the frontier of AI
ARIMLABS was founded on a simple conviction: those who understand how systems break are best positioned to secure them.
Our Story
We are two Ukrainians with deep roots in offensive cybersecurity — red teaming, penetration testing, vulnerability research, and adversarial operations. For years we operated on the frontlines, developing the attacker's perspective so organizations could stay ahead of real-world threats.
As large language models and autonomous AI agents began reshaping the technology landscape, we recognized a familiar pattern: powerful systems being deployed far faster than they could be secured. The same instincts that guided our offensive work now pointed toward a new frontier — AI security.
In 2025 we founded ARIMLABS with a clear mission: bring an adversarial mindset to the AI ecosystem. We research vulnerabilities in LLMs, autonomous agents, and AI infrastructure. We build the tools and frameworks that make these systems safer — with the rigor that only comes from years of hands-on security work.
We didn't pivot into AI security — we were built for it.
