How to know if a payment gateway is secure?

To determine if a payment gateway is secure, look for key features such as PCI-DSS compliance (Level 1 is the highest standard), data encryption, and tokenization. For Indian users, compliance with RBI mandates, including data localization and two-factor authentication (2FA), is essential. Reputable providers often display their PCI compliance status on their website or can provide a compliance certificate upon request. Secure systems also implement fraud detection.
