ShieldLabs

Fraud and abuse detection that recognizes visitors, bots and risky accounts under any masking

Visitor and device identification

Recognizes returning visitors across cleared cookies, incognito sessions and changed IP addresses, and links multiple accounts that trace back to the same person or device.

Ready-made High-Risk Events

Flags multi-accounting, account sharing, account takeover and impossible travel out of the box, with a confidence value per event and no fraud model training required.

Masking and bot detection

Names the risk signals behind each result: VPN, proxy, Tor, private relay, datacenter, anti-detect browser, incognito mode, JavaScript disabled, OS and timezone mismatch, browser automation and AI bots.

Risk scoring and traffic quality

Scores every visit 0–100 and classifies it as trusted, suspicious or dangerous, then aggregates a single traffic-quality score with breakdowns by channel, referrer and UTM campaign.

Strengths & Pros

+Full detection stack on every plan, including the free tier, so nothing critical is locked behind an enterprise quote
+Identification-led approach catches multi-accounting even when emails and IP addresses change
+Transparent usage-based pricing with hard caps and no overage surprises
