# ShieldLabs ShieldLabs is fraud detection and prevention with traffic quality scoring. It stops multi-accounting, account sharing, account takeover, fake signups and ad fraud. ShieldLabs stops multi-accounting, account sharing, account takeover, fake signups and ad fraud. It identifies visitors and users, detects anonymity at any level, and returns an explainable risk score with the anonymity signals behind it and ready-made patterns that point to abuse, with up to 99% accuracy. ShieldLabs surfaces the signals and the score, and you decide what each case gets, by your own rules. It helps you detect and prevent: - multi-accounting - account sharing - account takeover - free trial and freemium abuse - subscription abuse and paid-access sharing - promo and bonus abuse - referral fraud - coupon and discount abuse - ban and restriction evasion - giveaway and contest fraud - sybil attacks and airdrop farming - voting and survey fraud - ad fraud - traffic fraud It gives you the depth of visitor identification and abuse detection that enterprise platforms charge for, without enterprise pricing, sales calls, or annual contracts. ## What ShieldLabs does ShieldLabs helps teams: - identify visitors and users with a persistent ID that holds across sessions, cleared cookies, and IP rotation - detect anonymity at any level: VPN, proxy, Tor, Privacy Relay, and anti-detect browsers - score the risk of every visit from 0 to 100 with the signals behind it - surface ready-made patterns that point to abuse and fraud - assess traffic quality and its level of anonymity - deliver everything via API and webhooks, so your own rules decide what happens ## Key features ### Visitor Identification A persistent visitor ID that stays stable across sessions and accounts, even through IP rotation, cookie clearing, and incognito mode. An identity graph links related visitors, devices, and accounts. ### Anonymity Detection Real-time mismatch analysis across 100+ device, operating system, browser, network, and IP signals to detect VPN, proxy, Tor, Privacy Relay, anti-detect browsers, environment spoofing, and tampered devices, at any level of anonymity. ### Network Intelligence IP reputation, geolocation, and timezone analysis, with detection of anonymized connections and the real IP behind masked ones, up to 99% accuracy. ### Explainable Risk Score A risk score from 0 to 100 for every visit, with the scoring reasons and contributing signals, so it is never a black box. ### Ready-Made Patterns Eight pre-built patterns correlate accounts, devices, visitors, and IPs across your full traffic history and grade each flagged entity Suspicious or Dangerous: - Many Accounts on One Device - Many Devices on One Account - Many Accounts on One Local IP - Shared Local IP Across Multiple Accounts - Many Devices on One Visitor - Multiple Countries on One Account - Changing IDs on One Account - New Device and New Country They point to abuse such as multi-accounting, account sharing, account takeover, and ban evasion. Patterns live in the analytics dashboard and are not part of the webhook or API payload. ### API and Webhooks Visitor IDs, the risk score, anonymity signals, and detection flags delivered via API and webhooks in real time, so you can automate your own rules. No SDK required, just one JavaScript snippet. ### Traffic-Quality Analytics A breakdown of how clean your traffic really is and where the risk concentrates, in a real-time analytics dashboard. ## What ShieldLabs detects Anonymization methods, masking techniques, and abuse activity, detected through device intelligence and network analysis across multiple layers, in real time. It detects: - VPN detection: traffic routed through a VPN to mask the real IP address and location - Proxy detection: traffic routed through proxy servers of various types - Tor detection: connections through the Tor network - Privacy Relay detection: relayed connections such as iCloud Private Relay - Anti-detect browser detection: specialized browsers that spoof or rotate their fingerprint - Datacenter detection: connections from datacenter, cloud, and VPS providers - Environment spoofing and device tampering detection: attempts to hide or alter the real device, OS, or browser - IP reputation detection: IP addresses associated with known abuse and fraudulent activity - Location spoofing detection: timezone and geolocation mismatches indicating a masked or spoofed location - Suspicious paid click detection: low-quality or invalid clicks on paid campaigns from anonymized or datacenter sources - Abuse activity such as multi-accounting, account sharing, and account takeover, surfaced by the dashboard patterns ShieldLabs does not block or decide on its own. It surfaces the signals and the score; your code owns the decision to allow, review, or block. ## Use cases Where visitor identification and anonymity detection prevent abuse and fraud: - account takeover - account registrations and multi-accounting - free trial and freemium abuse - subscriptions and paid access - account sharing - plan and usage limit bypass - ban and restriction evasion - referral fraud - bonuses and promotional campaigns - giveaways and contests - ad fraud - traffic fraud - traffic quality and acquisition - cryptocurrency and Web3 reward campaigns - voting and ratings - surveys and data collection - coupon and discount abuse ## How it works ### 1. Install in about 5 minutes Add one JavaScript snippet to your site. ShieldLabs generates a persistent visitor ID on the first visit and starts traffic analysis and anonymity detection in real time. ### 2. Get a real-time risk score Anonymity signals and cross-layer mismatches roll up into an explainable risk score from 0 to 100 for every visit, plus an overall traffic anonymity level. ### 3. See the patterns An identity graph links visitors, devices, and accounts over time. Ready-made patterns surface suspicious connections and point to abuse and fraud, graded by severity. ### 4. Act on the details The risk score, scoring reasons, and detailed visitor data are available in the analytics dashboard or via API and webhooks. Build your own rules on top with the API and webhooks, automate workflows, and make informed decisions. You set the rules. ## Pricing The depth of visitor identification and abuse detection that enterprise platforms charge for, without enterprise pricing. Start free, then transparent self-serve pricing that scales with your traffic. Billing is per identification (per request).

It complements them with device and network signals, not government IDs or documents. - It does not identify individual people. It assigns a persistent identifier to a device or browser, not to a specific person. - It does not collect personal data such as names, email addresses, or passwords, and does not track people across different sites. - It does not use biometric fingerprints. Fingerprinting here refers to device and browser characteristics, not biometric data. - It does not sell or share customer or visitor data with third parties. ## FAQ summary ### What is ShieldLabs?
