What happened
Cloudflare announced general availability (July 13, 2026) of Precursor, a session-long behavioral validation engine that runs inside browsers to continuously score bot/agent automation (mouse movement, scroll rhythm, typing cadence) rather than relying on one-time CAPTCHA-style checkpoints.
Why it matters
With automated (including AI agent) traffic now reportedly exceeding human web requests, this is a broad-reach (Cloudflare's global network) shift from point-in-time to continuous behavioral defense specifically framed around the agentic AI traffic surge.
Applicability
Any Cloudflare customer running bot management should enable Precursor now; relevant to teams building/defending against autonomous browser agents.
