Cloudflare has launched Precursor, a behaviour-based bot defence system using continuous analysis to detect AI-driven automated bots that now account for 57% of web traffic and bypass traditional CAPTCHAs and login verification.
This Wire brief sits within Fusion42's coverage of Cybersecurity and Security Infrastructure. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ The Wire takeaway
If you're building anything that sites need to protect from bots—scraping defence, fraud detection, inventory management—your old playbook just broke. Cloudflare and competitors will now sell behaviour analysis as the new moat; your customers will demand it or build it themselves.
