ShieldLabs

About ShieldLabs

ShieldLabs is fraud and abuse prevention software for web products. It is aimed at teams that lose revenue to repeated trial signups, bonus abuse, shared logins, account takeovers, and fake or bot-driven traffic.

The product identifies returning visitors and devices even when they clear cookies, use incognito mode or change IP address, then links accounts that belong to the same person under different email addresses. It flags VPNs, proxies, Tor, anti-detect browsers and browser automation, and returns every visit a 0 to 100 risk score with the named signals behind it. A dashboard offers traffic quality analytics by source, channel and campaign, and an API and webhooks pass the data into existing business logic.

What sets it apart, according to the site, is ready-made high-risk event detection that needs no fraud model training, along with a free tier of 5,000 identifications and no credit card required.
