The perennial question, "Can AI Do Cyber Security?", has evolved from a theoretical debate into a pressing operational and architectural challenge for every CISO and security engineering lead in late 2025. Two years ago, we were still grappling with the hype cycles surrounding large language models (LLMs) and generative AI, trying to discern signal from noise. Today, AI, in its various forms—machine learning (ML), deep learning (and yes, LLMs)—is deeply embedded in our defensive stacks, from the endpoint to the cloud edge. It's no longer about *if* AI can assist, but *how effectively* it’s being deployed, integrated, and, critically, operationalized to counter an adversary that's also leveraging AI to refine their TTPs. The Current State of Can AI Do Cyber Security in Late 2025 As of September 21, 2026, the landscape is defined by a sophisticated interplay. We're seeing AI capabilities m
