Key facts

Network and Device Intelligence: 300+ device and network signals are collected together and cross-checked, delivering 99.9 percent identification accuracy and 99.9 percent risk signal detection accuracy. Vendor page ↗
Detection surface: Risk is evaluated with current device and network evidence rather than relying only on an IP blocklist. Browser masking, anonymization and repeat activity can be assessed together. Vendor page ↗
Ready-made account findings: Ready-made detection covers multi-accounting, account sharing, impossible travel and account takeover without building a separate fraud model or rule set. Vendor page ↗
Explainable result: Risk score and Trusted, Suspicious or Dangerous verdicts are available for visitors, users, devices and IPs, with named signal evidence for investigation. Vendor page ↗
Identity and context: Device ID supports continuity across sessions, cleared cookies and IP changes. Visitor and account context help connect repeated actions rather than count rotating addresses as unrelated customers. Vendor page ↗
Access and delivery: 5,000 free identifications. Starter: 99 US dollars/month for 25,000; Growth: 399 for 150,000; Scale: 999 for 500,000. API, webhooks, SDKs and chat/email support are available across plans. Annual billing offers a discount. Vendor page ↗

Strengths

Device, network and account evidence connect repeat abuse across signup, login and checkout.
Current observations help address stale IP lists and masked traffic while preserving the reasons behind a verdict.
Ready-made account detections reduce the work needed to turn raw identity attributes into useful fraud findings.
Enterprise-level functionality without enterprise pricing; free API access and published paid plans support a self-serve start.

Limitations

Collection must be installed on the protected flows and account events must be associated correctly.
Detection does not transfer a merchant’s card-chargeback liability; guarantee coverage is a separate purchasing decision.

Who it fits

SaaS, marketplaces, iGaming and digital-product teams that need explainable fraud detection and repeated-account abuse findings without an enterprise buying process.

Use the alternatives by evidence layer to compare user-risk layers, fraud operations, payment risk and commerce guarantees.

What the score means

The 9.6 out of 10 score is an editorial assessment under the same 36-criterion, six-category framework. The rubric emphasizes detection and signal depth, customer friction, explainability, coverage, integration and access. The published scale runs from 0 to 10.

The award and score are distinct. Read all criteria and relative weights and verify the required signal and integration for your traffic.

How to evaluate it

Compare known customers with authorized repeat-account, masked-network and account-change cases at signup, login and checkout. Inspect risk reasons, device and visitor references, account associations and the relevant High-Risk Event. Keep a user-level finding separate from an order guarantee.

FAQ

What does ShieldLabs add before checkout?

It provides visitor, user, device and IP risk context at signup, login and product actions, including ready-made account-abuse findings before an order or payment exists.

Can ShieldLabs replace an IP blacklist?

Current device and network intelligence adds connection and identity context that an IP list alone does not provide. Evaluate legitimate privacy-tool users alongside abusive activity rather than treating every VPN as fraud.

How can a small team try it?

Start Free includes 5,000 free identifications. Paid access starts at 99 US dollars per month for 25,000 identifications. The public checker offers an initial view of visit evidence.
