## 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

## ProofUp

ProofUp is a tenant screening platform built for multifamily property operators who need to confirm that an applicant can actually pay the rent. Instead of trusting whatever pay stub gets uploaded, it verifies income directly: applicants connect their bank and payroll accounts through Plaid, and earnings are read from the account rather than from a document. For those who upload instead, AI reads deposit frequency and actual earnings, which extends coverage to gig workers and guarantors.

The second layer is identity. A government-issued ID is photographed front and back, a live selfie is captured, and facial recognition confirms the two match — addressing the gap between the name on paper and the person who shows up. The third layer examines uploaded documents at the data level, checking file structure, metadata, and generator fingerprints for tampering that looks clean to the eye.

Everything converges into a single verdict per application — one of five, each carrying a risk level and the evidence behind it. Notably, the platform grades evidence quality: a direct bank connection differs from a source-downloaded PDF, which differs from a scan or phone photo. That distinction lets an approval team move fast while a review team still knows which applications deserve a sample. ProofUp positions itself against unverified approvals, which it says default far more often.

**Pricing & Plans:** Contact for pricing. ProofUp does not publish public tiers on its site; pricing is arranged through a demo request and depends on portfolio size and screening requirements.

- **Income verification from the source:** Applicants connect bank and payroll accounts through Plaid so earnings are read from the account itself, with no document in the path to forge. Uploaded documents are also analyzed for deposit frequency and real income.
- **ID plus live selfie matching:** A government ID photographed front and back is matched against a live selfie using facial recognition, catching borrowed identities before keys are handed over.
- **Document forgery detection:** Uploaded PDFs are read at the byte level for hidden text layers, metadata mismatches, generator fingerprints, and post-generation edits — evidence that visual inspection misses.
- **Five graded verdicts with reasons:** Each application returns one of five verdicts (pass, pass with caution, non-recurring, needs review, fail) with a risk level and the specific signals that produced it.
- **Auditable decision trail:** Reports record verification method, document source, per-attempt history, and plain-language flag explanations, so decisions are defensible and reviewable.

**Strengths:** Income is verified from the account via Plaid, so there is no forgeable document in the strongest path; Combines income, identity, and document-fraud checks in a single 2-3 minute flow; Five graded verdicts with explicit reasons and risk levels beat a simple pass/fail; Evidence-quality grading separates source-downloaded PDFs from scans and photos

**Limitations:** No public pricing — you must book a demo to get numbers; Strongest results depend on applicants connecting bank and payroll accounts, which some may resist; Document-level fraud analysis only applies to applicants who upload files rather than connect accounts
