Summary

Block's security team uses OpenAI Daybreak within what it calls the OpenAI Defense Factory to speed up vulnerability discovery, detection, and response. James Nettesheim, Block's Chief Information Security Officer, says the work that once took weeks now takes hours, with a human validating each result. The source says Block's security harness routes tasks to different models and includes human takeover hooks.
