Cloudflare Introduces Precursor to Detect Agentic Behavior Across Full Sessions

Precursor

I am excited to introduce Precursor, a new client-side verification system that continuously monitors behavioral signals throughout a user's entire session. Unlike traditional checkpoints, Precursor analyzes the rhythm and physics of human interaction to distinguish real users from sophisticated bots. This approach significantly improves detection precision while reducing friction for legitimate visitors, extending our protection beyond isolated moments to the full user journey.
