The cyber AI parity window now has a deadline

In April, I wrote about what I called the Cyber AI Parity Window . This is the rare period in which defenders and adversaries gained access to the same transformative technology at roughly the same moment. For most of cybersecurity history, advanced offensive capability reached attackers years before defenders could respond with comparable technology. AI changed that pattern.

At the time, my argument was simple. Parity creates an opportunity, and its value depends on what defenders do with it. I also warned that the window would narrow.

Five months later, we have a better sense of how quickly.

OpenAI recently described what it calls the “defender’s window.”
