Payment Fraud Prevention & Security Filters
Stop bad actors before they cost you a chargeback. Midcove's payment fraud prevention filters block risky IPs, emails, phones, and card ranges, and lock out repeat offenders automatically.
Stop fraud at the door, not after the chargeback.
Every fraudulent transaction you catch before it processes is a chargeback, a fee, and a headache you never have to deal with. Midcove layers rule-based filters and automatic lockouts on top of your gateway's own fraud tools, so risky attempts get stopped early.
- Block transactions by IP address, email, phone number, or card BIN.
- Automatic 24-hour lockout after multiple failed transaction attempts.
- Custom block lists you control and update at any time.
- Works alongside your gateway's existing fraud protection.
Filter types at a glance

Fraud prevention questions
What fraud filters does Midcove support?
Midcove's payment fraud prevention filters include IP blocking, email blocking, phone blocking, and BIN blocking, so you can stop known bad actors before they reach checkout.
How does the automatic lockout work?
When a customer racks up multiple failed transactions in a short window, Midcove automatically blocks them for 24 hours to stop card-testing and brute-force attempts.
Can I customize block rules?
Yes. You can add or remove entries from your IP, email, phone, and BIN block lists at any time, and adjust velocity thresholds to fit your business.
Does this replace my gateway's fraud tools?
Midcove's filters work alongside your gateway's existing fraud tools, adding another layer of protection on top of NMI, Authorize.Net, Stripe, or PayPal's built-in checks.
