Bot detection & web fraud · Kasada
Kasada
Bot and fraud defense platform that uses dynamic, polymorphic JavaScript and proof-of-work challenges instead of CAPTCHAs to detect automation.
Kasada protects web, mobile, and API traffic without presenting CAPTCHAs to users. Its core mechanism, Polyform, serves dynamic, polymorphic JavaScript and forces client devices to solve proof-of-work-style computational challenges that are cheap for a real browser but costly to reverse-engineer or replay at scale, aiming to make automated evasion economically unattractive rather than merely difficult. This client-side signal is combined with device, behavioral, and account-history telemetry across four linked products: Bot Defense, Account Intelligence for fraud rings and credential abuse, AI Agent Trust for classifying and controlling AI-agent traffic at the HTTP level, and Kasada IQ for pre-fraud warning signs. Kasada is typically deployed to replace or sit alongside incumbents such as Akamai Bot Manager, Cloudflare, or HUMAN Security. Pricing is not published and is quoted per deployment.
