San Francisco firm launches Precursor to fight bots | JQJO

SAN FRANCISCO - Cloudflare, Inc. on Monday, July 13, 2026, announced the general availability of Precursor, a next-generation behavioral validation engine designed to counter increasingly sophisticated automated bots. The San Francisco-based connectivity cloud company said Precursor responds to a major shift in internet traffic patterns, with automated bot activity now generating about 57 percent of global web requests and surpassing human browsing for the first time. Cloudflare described this as a structural change in how the internet operates, moving from an environment centered on human clicks to one where automated artificial intelligence agents dominate routine interactions with websites and online services.

Cloudflare said this transition has eroded the effectiveness of traditional security controls, including static CAPTCHAs and other one-time, point-in-time challenges that attempt to verify users at a single moment. According to the company, advanced bots can be programmed to imitate a specific action well enough to pass such entrance tests, making these defenses inadequate against modern automated threats. Cloudflare stated that Precursor instead focuses on ongoing behavioral validation across a user’s session, aiming to distinguish genuine human browsing patterns from automation and to provide website operators with more reliable protection as automated traffic becomes the norm on the internet.
