Why choose ShieldLabs

Ready-made detection, no rules to configure

Multi-accounting, account sharing, account takeover and impossible travel come ready, with Medium or High confidence and no rules to configure. With Sardine you configure the rules yourself in its rule editor, and it has no ready account sharing detection of its own.

Enterprise-level functionality without enterprise pricing

The full feature set on every plan, Free included, from 99 USD a month for 25,000 identifications, with no sales call. Sardine sells only on an enterprise contract, publishes no price, and bills platform fees and premium support on top of usage.

Transparent scoring

Every risk signal carries a published weight, so the same activity always gets the same score. Sardine scores with machine-learning models trained on consortium data, runs them through rules you configure yourself, and publishes no weights, a black box where a false positive cannot be traced to how much each signal counted.

Risk analytics and investigation

Investigate visitors, devices and IPs, each rated Trusted, Suspicious or Dangerous, and see the overall risk across all your traffic and by source, channel and UTM. Sardine rates user sessions, customers and devices, with no risk level for IPs and no traffic source or UTM breakdown.
