Fraud prevention

Stop abuse before it compounds

Every identify call returns an eventId your backend can enrich within five minutes. Fetch suspect scores, smart signals, and ruleAction server-side — then block, challenge, or review before losses scale.

Bot, VPN, proxy, tampering, and velocity signals computed after geo and visit history
Limiter presets (signup-strict, marketing-balanced) auto-block abusive identify traffic
identifyOnDemand before OTP, checkout, payouts, and password reset
Conservative merge policy + bootstrapToken: 'auto' for high-risk signup flows

Account integrity

One person, one account — enforced

Stitch anonymous browsing to authenticated users with linkedId on identify. At registration, POST /api/account-link scores whether the email already maps to a high-confidence visitor — without invasive KYC on every page view.

linkedId and tags metadata on every identify call
Account-link API for duplicate registration and colliding-email detection
Visitor search, timeline, and exports in the dashboard console
Peer-collision guards when conservative merge policy is enabled

Checkout & payments

Protect high-value moments in the funnel

Trigger a fresh identify before checkout, wallet top-up, or bank-linking. Gate the transaction on confidence, suspect score, and smart signals — not on browser-visible fraud fields that attackers can tamper with.

Slim SDK response in production; authoritative enrichment via GET /api/events/:eventId
Step-up auth, 3DS, or manual review when riskLevel exceeds your threshold
Returning-visitor confidence helps distinguish loyal customers from session replay
Webhook delivery for async review queues and case management tools

Bot & automation defense

Filter automation before it reaches your product

Headless browser, automation framework, and tampering heuristics run client-side; verdicts are computed server-side on every identify. Enabled Limiter rulesets can reject abusive traffic at the edge of your identify endpoint.

Bot and anti-detect browser flags in smartSignals on Events GET
Suspect score and structured riskLevel for rules and queues
Rate limits and identify-time blocks via Limiter rulesets
Optional Fingerprint-compatible export for side-by-side evaluation

Growth & analytics

Measure real users, not sessions

Attribute campaigns, experiments, and product funnels to persistent originIds — even when third-party cookies are blocked, IPs rotate, or users browse in private mode.

Stable originId for warehouses, CDPs, and product analytics pipelines
Returning-visitor confidence and match level on Events GET
Cross-subdomain identification with consistent first-party clientToken
Tags on identify for campaign, cohort, and experiment metadata

Personalization

Recognize guests without forcing login

Tailor onboarding, offers, and support for returning visitors before they authenticate — while respecting slim browser payloads, configurable retention, and honest confidence limits on shared devices.

Guest-to-known-user stitching via linkedId at login or signup
Incognito-aware collection — no clientToken persisted in strict private modes
Hosted retention policies with configurable visit purge (default 12 months)
Personalization rules keyed on confidence bands, not originId alone

Security operations

Feed your SOC and case tools

Export visitor timelines, wire webhooks on high-risk identifies, and evaluate inline with ruleset_id on Events GET. Management API keys and MCP server support fit into existing security engineering workflows.

Webhooks with signed payloads for async enrichment and alerting
Security audit exports and high-risk visitor views in the console
Management API for projects, keys, rulesets, and usage from CI/CD
Server-authoritative model — fraud fields never trusted from the browser

B2B & enterprise Fintech Healthcare Insurance

Industries

Built for teams across every vertical

DigitalFingerprint deploys wherever visitor identity, fraud signals, and account integrity matter — from consumer apps to regulated enterprise workflows.

Payments, lending, and neobanks

Fintech

Block promo abuse, account takeover, and synthetic identity at signup, login, and payout — with server-side suspect scores on every identify.

Checkout, loyalty, and returns

E-commerce & retail

Recognize returning shoppers across devices and incognito sessions. Step up verification before high-value checkout, refunds, and coupon redemption.

Buyers, sellers, and trust & safety

Marketplaces

Detect duplicate seller accounts, ban evasion, and coordinated fraud rings with persistent originIds and account-link scoring at registration.

Trials, seats, and referrals

SaaS & subscriptions

Stop trial farming, seat sharing, and referral abuse. Tie anonymous visits to linkedId as users convert from guest to paid workspace.

Players, bots, and fair play

Gaming

Surface smurf accounts, bot farms, and region-policy violations. Limiter presets can block abusive identify traffic before it hits your game servers.

Students, credentials, and access

EdTech

Protect certification flows and paid course access from credential sharing. Conservative merge policy reduces false merges on shared school hardware.

Patient portals and telehealth

Healthcare

Strengthen portal login and appointment booking with device-aware risk signals — enrichment stays server-side for HIPAA-conscious architectures.

Bookings, loyalty, and cancellations

Travel & hospitality

Identify repeat bookers and flag suspicious cancellation or loyalty-point abuse without relying on third-party cookies across booking flows.

Subscriptions and paywalls

Media & publishing

Meter paywalled content and reduce credential sharing with stable visitor handles across browsers, VPNs, and private browsing modes.

Quotes, claims, and policy changes

Insurance

Gate sensitive policy changes and claims intake with confidence-aware rules. Correlate anonymous quote sessions to accounts at bind time.

On-ramps, wallets, and exchanges

Crypto & Web3

Detect multi-account abuse at fiat on-ramp and exchange signup. Velocity and IP intelligence corroborate client-side VPN hints server-side.

Self-serve signup and seat governance

B2B & enterprise

Score duplicate org signups and API-key abuse. Webhooks and Events GET feed your SIEM or internal risk queues without exposing fraud fields in-browser.
