CAPTCHA evolves from puzzle to invisible behavioral scoring system

Why it matters
This shift from visible puzzles to passive behavioral scoring changes the economics of web scraping and anti-bot evasion. Practitioners can no longer rely on solving visual challenges alone; they must now contend with opaque risk scores that penalize non-human browsing patterns. The concentration of CAPTCHA technology in just two vendors also creates a single point of failure for both defenders and scrapers.

Will the duopoly of CAPTCHA vendors lead to standardized evasion techniques or push defenders toward even more opaque detection methods?
