There are four different types of GeeTest CAPTCHA.

Intelligent mode
Slide CAPTCHA
Icon CAPTCHA
Space CAPTCHA

Here is a detail of all of them.

Intelligent mode

In this mode, ONLY high-risk visitors will be provided with CAPTCHA challenge. The system will automatically decide to let the user pass the test, pop out Slide or Icon CAPTCHA challenge based on the detected risk.

This one is not that secure. GeeTest itself rated it 2 out of 5 for its security strength. For user experience, 5 out of 5.

Slide CAPTCHA

When the user drags the slider, the mouse tracks, device attributes, and some other data will be collected and analyzed in real-time.

This one is much secure than the previous one. GeeTest itself rated it 3out of 5 for its security strength. For user experience, 4 out of 5.

Icon CAPTCHA

The neural network has been applied to switch image styles rapidly. The mouse tracks, device attributes, and some other data will be collected and analyzed to differentiate humans from bots.

GeeTest itself rated it 3 out of 5 for its security strength. For user experience, 4 out of 5.

Space CAPTCHA
