What topics does the FraudPulse blog cover?

The FraudPulse blog covers how to tune Stripe Radar, Shopify Flow, Blockify, and Adyen RevenueProtect from your own chargeback mix: chargeback reduction, friendly fraud, false declines, card testing, Visa VAMP thresholds, and fraud rule audits. It is about prevention and rule decisions, not order screening or chargeback representment.

Does FraudPulse replace the fraud tools covered on the blog?

No. Stripe Radar, Shopify Flow, Blockify, and Adyen RevenueProtect stay the enforcement layer at checkout. FraudPulse is the AI analyst: it classifies chargebacks and ranks which of their rules to change, each with an estimated fraud-capture rate and false-positive percentage.

Who writes the FraudPulse fraud guides?

Guides are written by Idan Hayon, Co-Founder & CEO of FraudPulse, drawing on more than a decade in payments fraud analytics at companies such as Riskified and Melio. Posts focus on practical operator advice, not generic theory.

Are FraudPulse blog posts only for Stripe and Shopify merchants?

No. Many examples use Shopify or Stripe because those stacks are common, but the core ideas - connecting transaction data, measuring false positives, auditing rules, and reducing chargebacks and friendly fraud - apply across ecommerce payment stacks including Adyen.

How often is the FraudPulse blog updated?

New posts are published regularly with product insights, industry threshold changes, and operator playbooks. Check the date on each article for freshness; the blog index lists the latest guides first so you can find current chargeback and fraud-ops advice quickly.

Declining More Transactions Reduces Fraud - and Loses Good Customers

The easiest way to reduce fraud is to decline more. It is also one of the easiest ways to lose good customers. Why VPN, new customers, and other signals are context - not automatic decline reasons.

One of the Biggest Mistakes in Fraud Prevention Is Assuming Every Decline Is a Win
