AI solves CAPTCHAs faster than your users can. Verena uses device biometrics to prove someone is human — one tap, zero data collected, impossible for bots to fake.

CAPTCHAs Punish Users.
Bots Don't Care.

AI models now solve reCAPTCHAv2 with a 100% success rate1 — faster than humans ever could. The technology designed to tell humans and bots apart has become a speed bump for your users and an open door for attackers.

Meanwhile, 23% of users abandon2 after a single failed attempt. Every puzzle costs you revenue. CAPTCHA-solving services charge $0.002 per solve — bulk bypass is trivial and essentially free.
