Human Challenge: User-friendly CAPTCHA-alternative

Included in HUMAN’s bot management solutions for both web and mobile applications, Human Challenge weeds out bad bots without adding friction to the user experience.

Easy for humans,
hard for bots and AI

HUMAN inspects every digital interaction, but only challenges suspicious requests—providing detection accuracy while preserving an uninterrupted consumer experience.
0.01% false positive rate
Human Challenge uses advanced techniques and strong anti-tampering mechanisms that make it difficult to solve through automation, AI, API calls, or CAPTCHA farms.
Invisible to humans
In 99.99% of cases, real users move forward without ever seeing Human Challenge. When they do see it, Human Challenge is fully customizable and brandable.
Adaptive learning feedback loop
Human Challenge gathers signals from the bots it defeats and uses that data to continuously strengthen mitigation workflows as bots evolve.

How it Works

Human Challenge displays a button that users “press and hold” while it makes a bot-or-not decision. ​​It is the only ADA, WCAG 2.2, and privacy compliant CAPTCHA and is available in 27 languages out-of-the-box.

Detect and challenge
HUMAN’s decision engine collects information on every interaction, automatically serving the Human Challenge when behavior that deviates from the normal human range is detected.
Collect
While the user completes the “press and hold,” Human Challenge tests the user’s device to solve proof-of-work challenges and collects additional signals.
Enforce

Once the “press and hold” is completed, humans are allowed to seamlessly continue to the application, while bots are prevented from continuing.

Learn
Data from successful and failed challenge solve attempts are fed back into the system, dynamically adjusting the detection on the application.
