For PSPs, gateways and payment facilitators

Fraud happens on the payer’s screen, and you end up footing the bill.

Your processing is secure, but the moment the payer sees the QR code, types a card number or copies a payment code happens in the browser, outside your infrastructure. Proteside closes that last stretch for your entire merchant portfolio, with one integration.

  • Wholesale pricing per active merchant
  • PCI DSS evidence per merchant

The problem, from the provider’s side

  • Disputes, refund claims and chargebacks

    A diverted payment or a card copied on the checkout turns into disputes, refund requests (such as MED for Pix), operating costs and unhappy merchants, all in your workflow.

  • Your brand is on the screen

    On your hosted checkout, payment link or SDK, the name the payer sees is your product’s. One tampering incident hits trust across your whole portfolio.

  • Growing responsibility

    PCI DSS requires script management and tamper detection on payment pages, and the market expects more and more from providers.

The business case

Preventing it on screen costs less than disputing it later

Every diverted payment means support work, investigation and friction, and often the money never comes back.

  • Beforesettlement: the check happens at the moment of payment, not after the dispute.
  • 1 integrationin your hosted checkout, payment link or SDK protects your entire merchant portfolio.
  • New revenueprotection can be sold as a premium feature per merchant, at wholesale prices with a resale margin.

What payment providers get

  • Integrity in every transaction

    QR code, payment key, amount and payment fields checked on the payer’s screen, with tampering blocked before confirmation.

  • Every payment method you process

    Cards, crypto, Pix, boleto and global instant payment rails, all in the same layer.

  • Multi-merchant API

    Activate, configure and monitor each merchant programmatically.

  • Compliance evidence

    Script inventory and change detection for 6.4.3 and 11.6.1, ready for QSAs and acquirers.

  • Part of your offer

    Offer the protection as part of your package or as an add-on, with a single invoice and wholesale pricing.

One layer for every payment method in the world, on your page

Partnership and distribution

How to buy

A distribution partnership, priced per active merchant:

  • Tiers by number of active merchants, with volume discounts
  • One monthly invoice for your entire portfolio
  • Partner dashboard with every merchant
  • Pilot with real transactions from your flow

The proposal is built around the size of your portfolio and the payment methods you process.

No payment provider should discover payment tampering after settlement. Proteside checks before.

Frequently asked questions

Does Proteside replace a payment provider’s fraud prevention?

No. Fraud prevention assesses the risk of the payer and the order; Proteside guarantees the integrity of what is shown on the payment screen. The two layers complement each other.

How does Proteside fit into a PSP’s infrastructure?

Through the presentation layer: hosted checkout, payment link or SDK. One integration covers your merchant portfolio, with no changes to processing.

Does it work for cards, Pix and other payment methods at the same time?

Yes. The same layer covers cards, Pix, boleto, wallets, crypto and international instant payment rails.

How does resale work?

Wholesale pricing per active merchant and a single invoice for the provider, which tracks every merchant in a partner dashboard.

The moment of payment is the same. Your business isn’t.
