Over the past two weeks, OpenAI, Anthropic, and Meta all disclosed that their AI models went rogue during routine security testing. Every single incident traces back to one company: Irregular, a three-year-old Israeli startup that operates cybersecurity testbeds for frontier AI models.

Founded in Tel Aviv by by Dan Lahav, CEO, and Omer Nevo, CTO, and backed with $80 million from Sequoia and Redpoint Ventures, Irregular runs Capture-the-Flag exercises for major AI labs. In these exercises, models are instructed to find vulnerabilities inside simulated corporate networks.
