Fight listing fraud. Protect your community.
Fake listings, review manipulation, and seller fraud destroy marketplace trust. CertiLayer detects the bots behind them without adding friction to real users.
THE PROBLEM
Bot fraud undermines marketplace trust
Every fake listing, manipulated review, and fraudulent account erodes the trust that makes your marketplace valuable.
Fake Listings
Bots post thousands of fraudulent listings — counterfeit goods, rental scams, non-existent items — at scale.
Review Manipulation
Scripts post fake positive reviews for favored sellers and coordinated negative reviews for competitors.
Fake Seller Accounts
Bots create thousands of seller accounts to conduct fraud before detection and account suspension.
Payment Fraud
Stolen cards and taken-over accounts make purchases that will be charged back, hitting your margins.
Price Scraping
Competitor bots scrape your pricing data in real-time to undercut your sellers systematically.
Metric Manipulation
Bots inflate view counts and engagement metrics to manipulate your search rankings and recommendations.
