Stop the bots that cost you revenue

Prosopo defends against web scraping, credential stuffing, account takeover, click fraud, ticket scalping, inventory hoarding, loyalty abuse, checkout automation, phishing attempts and spam bot submissions — distinguishing malicious automation from legitimate humans and trusted AI agents instead of binary block/allow.

Prosopo takes a different design route from DataDome, Kasada, HUMAN and Arkose. When Prosopo stops a bot, the block response carries the reason — Inconsistent hardware readings for device, Solver service detected, Synthetic interaction timings, HTTP header fingerprint mismatch — not a numerical risk score, not a vendor-branded policy label. Your team knows what caught the request without opening a support ticket. Our base captcha is open source on GitHub and self-hosting is available. See the Forrester Wave Bot and Agent Trust Management Q2 2026 breakdown for the full comparison against DataDome, HUMAN, Kasada, Arkose Labs, CHEQ, Netacea, hCaptcha and Google reCAPTCHA Enterprise, or compare vendors one page at a time, including where we would tell you to buy someone else.

Prosopo provides better user experience with privacy-first design and lower costs. While reCAPTCHA relies on data collection and hCaptcha's data compliance is questionable, our dynamic risk assessment minimizes challenges for legitimate users.

Bot and agent trust management is the software category name Forrester adopted in late 2025 to reflect that AI agents now sit between humans and traditional bots. Instead of binary block/allow, the discipline asks vendors to identify the intent of every automated request and make ongoing trust decisions for humans, agents and bots alike. Prosopo's Decision Machines rule engine, Catcher behavioural SDK and agent whitelist rules are all designed around that trust-first model.

Both. AI agents like ChatGPT's shopping agent, Claude's computer-use agent and Perplexity's browser act on behalf of real users — block them blindly and you lose customers, allow them blindly and you invite abuse. Prosopo treats agent identity as a first-class signal: granular agent permissions, behavioural verification, and agent whitelist rules that distinguish a trusted agent acting for a real customer from a malicious bot.

Prosopo uses behavioral analysis, JavaScript signals, and proof-of-work challenges to identify bots in real-time. Our machine learning analyzes hundreds of signals to dynamically adjust protection levels.

Yes. Prosopo automatically whitelists beneficial bots like search crawlers, supports per-agent permissions for AI agents acting on behalf of real users, and blocks malicious traffic — all from the same rule engine. Our custom rules ensure legitimate automation and trusted agents maintain access while preventing unauthorized scraping and spam bot abuse.

E-commerce, fintech, gaming, media, SaaS and healthcare — anywhere a false positive costs a real customer and a black-box block is hard to defend. Prosopo's detector library provides every block with a technical, human-readable reason string — so your team can explain to a CFO or a DPO exactly what caught the request, and add a custom Access Rule if the default doesn't match what you're seeing.

Yes. Prosopo is GDPR compliant, with a data processing agreement on every plan. Data is collected for the purpose of fraud prevention only. We do not track users or sell data.

Protect runs on Cloudflare Workers or AWS Lambda@Edge, so there is nothing to install on your servers. We set it up with you on a call, then it watches your traffic in preview mode for 14 days before it blocks anything. If you only need to protect a form, Procaptcha is a script tag and is free to start.
