Bot Protection That Doesn't Compromise on Privacy

Prosopo stops automated abuse — credential stuffing, scraping, fake signups, ticket bots — without the third-party tracking most vendors rely on.

Platform Features

Trust-first verification

Every request is scored for trust. Legitimate humans pass invisibly, trusted agents are recognised, abusive automation is blocked at the door.

Network-wide behavioural modelling

Patterns learned across the entire network apply to every protected site. New abuse infrastructure is caught the moment it appears anywhere — not after it reaches you.

Privacy-first by design

No third-party tracking, no cookies, no data sold on. GDPR-, CCPA- and SCC-compliant out of the box — legal sign-off takes hours, not weeks.

Adaptive ML, retrained continuously

Models update against new bot infrastructure patterns continuously. Coverage extends as attackers adapt, with no manual rule maintenance on your side.

Deploy where your traffic is

Runs on Lambda@Edge, Cloudflare Workers, Fastly, or as a direct backend integration in PHP, Node, Python, Go and Ruby. Sub-40ms verification decisions.

Residential proxy & device-farm detection

Identifies traffic routed through residential proxy networks, real-device farms and other infrastructure designed to look legitimate — even when the IP itself looks clean.

Prosopo's CAPTCHA widget

I've installed Prosopo's CAPTCHA widget on my website to filter out spam from my contact form. Getting it working was a little bit tricky but the support from Chris has been first class.
I wanted to use a CAPTCHA which was as easy as possible for my website's visitors while respecting their privacy and which didn't use cookies. Prosopo's CAPTCHA meets all these criteria.
Update - after more than a week I haven't had a single spam form submission.

Effortless Integration and Outstanding Support with Procaptcha

I use Procaptcha with React. Procaptcha has been very easy to implement as they maintain a wrapper component that can be easily pulled from NPM. They have incredible customer service and are happy to answer any questions I have or help their community with their product. The component itself is flexible, allows styling with inline CSS, and even allows for theming. The puzzle is also not too difficult to solve and is a great middle ground as far as Captchas go. I originally came from using Cloudflare Turnstile and hCaptcha and have enjoyed my experience with Procaptcha significantly more.

Switching to Prosopo's Procaptcha was a massive improvement over other solutions we've previously tried which include hCaptcha and reCaptcha.

We managed to greatly reduce the friction and churn rate of our users
