About Prosopo

Prosopo is an open source project dedicated to making the internet a place people can use with confidence, while empowering businesses to know their users are legitimate. We stop bots from abusing forms, scraping protected data, and creating headaches for website and app owners.

Existing bot protection services are invasive for users and expensive for their clients. We change that by being transparent and privacy focused. We're proudly GDPR compliant.

Our approach builds on traditional systems, but with a twist: we collect as little information as possible. Cryptographic proofs let us send the minimum data to the server, which can verify it without learning anything about the user.

We're UK-based, fully remote, and work four days a week.
