## hCaptcha

hCaptcha is one of the largest independent online security platforms, used to protect hundreds of millions of users worldwide. Its core is a real-time bot-detection engine that separates good traffic from attackers without collecting personal data. Developers can swap reCAPTCHA with just two lines of code, and hundreds of plugins and native integrations simplify rollout.

Beyond classic CAPTCHAs, hCaptcha Enterprise adds fraud protection for payments, account-takeover detection that works with any identity provider, and a novel pull-based MFA that avoids SMS toll fraud. Private Learning builds custom risk models on privacy-preserving signals, while Advanced Threat Signatures cluster attackers across thousands of IPs and devices with nearly zero false positives. It works in every country and meets GDPR, CCPA, HIPAA, LGPD and PIPL standards.

Options span a free publisher tier, a Pro plan for growing sites, and Enterprise plans with multi-user dashboards, SAML SSO, advanced reporting and SLAs. Accessibility features such as text-based challenges and a passive Universal Accessibility system help meet WCAG 2.1 requirements.

**Pricing & Plans:** Offers a free publisher tier, a hCaptcha Pro plan for lighter bot protection, and Enterprise plans with custom pricing for advanced bot, fraud and account-defense features. A free trial of Pro is available.

- **Real-time bot detection:** Multi-layered detection delivers risk scores and near-zero false positives, with passive and no-CAPTCHA modes.
- **Fraud and account defense:** Stop transaction fraud, account takeovers and multi-accounting with privacy-preserving signals and no PII.
- **Pull-based MFA:** A stronger, toll-free alternative to SMS MFA that reduces fraud while simplifying the user experience.
- **Private Learning and risk insights:** Build custom risk models with adaptive learning and enrich your own ML using blinded, compliant signals.
- **Easy migration and integrations:** Switch from reCAPTCHA in two lines of code, with hundreds of plugins and native integrations.

**Strengths:** Privacy-first design with zero PII and global compliance; Easy two-line migration from reCAPTCHA and broad integrations; Enterprise-grade fraud, ATO and MFA features with strong accessibility

**Limitations:** Advanced fraud and account-defense features require Enterprise pricing; Free tier is limited to core bot protection without Pro/Enterprise reporting

## Roundtable (Proof of Human)

Roundtable began as an AI-powered fraud prevention platform and now operates under the name Proof of Human (Proof of Human, PBC). The roundtable.ai domain redirects to poh.org, and the site explicitly describes the company as formerly Roundtable AI, so the underlying product and team remain active — simply under a new brand and mission framing as a public benefit corporation.

The core of the product is an invisible verification API. Instead of asking users to solve puzzles, it watches how they interact with a page: how they type, where the mouse travels, how they scroll, whether they paste text or leave typos uncorrected, and how their clicks land. Those signals roll into a live behavioral profile that distinguishes real humans from scripts, bots and increasingly capable AI agents. Verification is continuous rather than a one-time gate.

Because the approach is behavioral rather than identity-based, the company emphasizes privacy: no PII is collected and no cross-site tracking is performed. Integration is a single script with a site key and user ID, and the platform reports millions of sessions processed each month with sub-200ms latency backed by SLA guarantees.

Use cases cluster around market research (verifying panel respondents), financial services (account creation and high-risk transactions), ticketing and live events (stopping scalper bots), and general fraud, bot and account takeover prevention. Pricing is quote-based and available by contacting sales or booking a demo.

**Pricing & Plans:** Roundtable (Proof of Human) does not publish public price tiers; pricing is quote-based and available on request. Prospective customers are directed to book a demo or email the sales team to discuss enterprise pricing and volume.

- **Invisible, Frictionless Verification:** Proof of Human runs silently behind login and checkout flows, scoring behavior in under 200 milliseconds without CAPTCHAs or friction for real people.
- **Continuous Behavioral AI:** Continuous behavioral models look for programmatic typing, teleporting mouse movement, jump scrolling, centered clicks and pasted text to catch bots and AI agents mid-session.
- **Privacy-Preserving by Design:** The service states it collects no PII and does no cross-site tracking, helping teams meet compliance and privacy requirements.
- **Effortless Integration:** A single script tag with a site key and user ID is enough to begin verifying sessions, and results include an example session report with explainable signals.
- **Enterprise-Scale Performance:** The platform reports millions of sessions processed monthly and near-instant API latency with SLA guarantees, suited to high-traffic consumer flows.

**Strengths:** No CAPTCHAs, popups or friction for genuine users; Continuous behavioral scoring rather than a one-time human check; Detects modern AI agents as well as classic bots; Privacy-preserving: no PII and no cross-site tracking

**Limitations:** Pricing is quote-based, so buyers cannot self-serve or compare costs upfront; Enterprise buyers must go through a demo and sales process; Continuous behavioral verification can raise privacy review questions before deployment; Previewed prices and plans are not published on the site
