AI is already accelerating penetration testing. In a verified benchmark, an AI platform matched a veteran’s success rate in about half an hour while the human needed forty hours. The deep dive explains where that speed helps in practice, including triaging scan output, suggesting exploits, and drafting reports. It also covers what not to automate, including creative chaining and social engineering. You will get practical guardrails such as running private models, sanitizing inputs, and verifying every finding. I close with a realistic playbook for treating AI like a junior copilot while tracking attacker use of generative AI.
