# Castle

A bot and account abuse detection platform selling IP intelligence, device fingerprinting, and behavioral analysis APIs to stop fraud.

**Route:** surfaced by the fraud prevention and risk management lane's de-branded queries → competitor to stripe.com.

**Why it's on the map:** Sells fraud-detection and abuse-prevention APIs to the same online businesses that would use Stripe's Radar or other Stripe fraud tools, and a buyer choosing Castle would not need Stripe's built-in fraud capabilities.

**Receipts** (verbatim from its page this run):

> Stop bots and account abuse at scale

> IP Intelligence API

> Device fingerprinting 99.5% accurate fingerprinting
