When are we going to move past the premise that Proof of Work stops bots? Proof of Work requires solving a computational problem that any modern dat computer or phone can solve in less than 1s. For bot operators, this is at most an annoyance. In order to stop scraping and automation at scale you have to do real threat detection and intercept requests from residential proxies / VPNs / data centres.

Nice captcha solution, it's easy to add onto existing projects and it's better from a user flow perspective as the user doesn't have to solve any tedious challenges
What is Private Captcha?
Private Captcha is an independent, privacy-first, self-hostable Proof-of-Work CAPTCHA service made in EU. Instead of asking users to solve complex puzzles or track their behavior, Private Captcha solves an invisible cryptographic task in the background. The system automatically adjusts the task difficulty, ensuring smooth access for real users while making it too costly for bots to attempt. Cryptographic task provides equal security regardless of bot's intelligence level, making it effective even as AI technology improves. Additionally, Private Captcha does not use cookies or track visitors and is fully GDPR-compliant that makes it easy to use for organizations that do business in EU.

When are we going to move past the premise that Proof of Work stops bots? Proof of Work requires solving a computational problem that any modern dat computer or phone can solve in less than 1s. For bot operators, this is at most an annoyance. In order to stop scraping and automation at scale you have to do real threat detection and intercept requests from residential proxies / VPNs / data centres. IP reputation, behavioural metrics, and defensive, obfuscated code that identify bot signals are all needed to even stand a chance at stopping bots. Enough with the "Proof of Work stops bots" lies!
Nice captcha solution, it's easy to add onto existing projects and it's better from a user flow perspective as the user doesn't have to solve any tedious challenges
Very simple to integrate. No fuss and follows compliance with a user-friendly experience.
For me personally it's been easy integration and it also has good support!
Works like a charm. Easy to use. One of the best features is the compliance with EU GDPR.
Easy enough to integrate, and I'm happy to support European tech.
easy to use, easy to integrate EU GDPR captcha
