Building an evidence-grounded agentic security operations harness on Cloudflare

What happened

Building an evidence-grounded agentic (AI that carries out multi-step tasks rather than answering one question) security operations harness on Cloudflare, Cloudflare Blog announced. Cloudflare Managed Defense operates with a team of specialized AI agents built on Workers and global network telemetry to analyze security alerts. Security alerts rarely arrive one at a time. Cloudflare is an information and communications technology company based in San Francisco.

A single alert can cause a spike across the environment, requiring a human analyst to decide which alerts are related and what they mean. When multiple arrive at the same time, it can quickly overwhelm even a seasoned security analyst.

Cloudflare operates with approved OpenAI Daybreak and Anthropic models, including GPT-5 (large language model by OpenAI).6 Cyber and Mythos, for deeper model-backed analysis. Initial analysis and scoring is done with Clef , Cloudflare’s open-source decision model.
