Best CAPTCHA Software for Startups

The service identifies requests similar to automatic ones, identifies bots, and filters them out without loss of response speed. For analysis, we use ML models trained on datasets containing data on many years of experience in protecting Yandex web resources. The datasets are regularly updated. The service does not use ready-made images, but generates them independently, making it possible to maintain an 85% level of human recognition while making it difficult for bots to recognize the CAPTCHA. SmartCaptcha is deployed in the Yandex Cloud infrastructure, which complies with international standards and Russian information security laws.
