Protect Your Business from Fraud

Advanced fraud detection and prevention tools to safeguard your revenue, reduce chargebacks, and maintain customer trust. Stay one step ahead of fraudsters.

Common Types of Payment Fraud

Understanding fraud types helps you implement the right defences

High Risk
Card-Not-Present Fraud

Online or phone transactions using stolen card details. Card never present, so chip & PIN doesn't help you.

High Risk
Account Takeover

Fraudster gets into a real customer's account. Usually via phishing, a leaked credentials database, or a well-pitched social engineering call.

Medium Risk
Friendly Fraud

Customer disputes a charge they actually authorised. Often months later, filed with their bank rather than emailing you.

High Risk
Identity Theft

Stolen personal data used to make purchases or open new accounts.

Medium Risk
Refund Fraud

Abusing your refund policy. Items returned that were never bought, or already kept.

Medium Risk
BIN Attacks

Automated card-number testing against a known BIN range to find live numbers.

Monek Fraud Protection Tools

PCI DSS Level 1 security on every account

Included
3D Secure 2.0

Pushes the liability for a successful auth onto the card issuer, not you.

Included
Address Verification (AVS)

Billing address checked against the issuer's records on every CNP transaction.

Included
CVV Verification

Asks for the 3-digit security code so the cardholder has to be looking at the physical card.

Included
Velocity Checks

Multiple rapid attempts from the same IP or card get flagged automatically.

Included
Device Fingerprinting

Tracks the device, not the customer. A fresh fingerprint trying ten cards in a minute is not a returning shopper.

Included
Real-time Fraud Scoring

Each transaction gets a risk score in milliseconds.

Included
Blocklists & Allowlists

Block known-bad IPs, cards, and emails. Allowlist your VIP customers so they never get challenged.

Included
Geolocation Checks

Flags when billing and shipping aren't where the customer usually lives.

Fraud Warning Signs

Learn to spot the telltale signs of fraudulent activity before processing transactions. Early detection is your best defence.

If you notice multiple red flags on a single order, it's worth taking extra verification steps or declining the transaction altogether.
