Fraud prevention by industry
The same signals matter differently depending on what you sell. A VPN on a developer-tools signup is an ordinary customer; the same VPN on a licensed betting account is a compliance problem. These pages cover what fraud actually looks like in each sector and where to set your thresholds.
Free trials are the cheapest thing on the internet to abuse. Stop trial farming without adding friction for real buyers.
Card testing, promo abuse and reshipping fraud all start with a signup or a checkout that looks slightly wrong.
KYC-adjacent screening at signup, before an account exists to launder anything through.
Bonus abuse, multi-accounting and geo-restriction evasion — the three problems every operator has.
Two-sided trust: a bad seller costs you more than a bad buyer, and both arrive as ordinary signups.
Paying for leads that bounce, or for a form filled in by a bot, is a direct and measurable waste.
Spam rings, sockpuppets and ban evasion, without demanding a phone number from every new member.
Free API tiers get farmed. Protect the tier without making your best users prove themselves.
