How Block is building AI-powered security with OpenAI technology

What happened

Block, the company behind Square, Cash App, and Afterpay, is using OpenAI’s Daybreak AI system to speed up its security operations, cutting tasks that used to take weeks down to hours. The AI handles vulnerability discovery, detection, and response, allowing the security team to focus on strategic work while still validating results. By replaying detection changes against seven months of telemetry in under an hour and automating triage, the team achieved a 50% boost in throughput and investigation capacity, handling roughly 1,100 analyst‑hours per quarter. Different models are chosen for specific tasks, and humans can intervene when needed, creating a more flexible, autonomous hunting capability.

Why it matters

This means faster detection and fixing of security issues, which can protect users’ financial data more effectively. It also shows how AI can augment, rather than replace, human security experts.
