How to efficiently fight against fraud?

As a platform, you are in charge of a permanent first level customer due diligence, using the support of your commercial and technical team. To maximise your platform security, we recommend that you:

  • supervise the behaviour of your clients on your platform
  • detect unusual behaviour or transactions and notify our teams at fraud@mangopay.com and wait for our Fraud Analyst feedback
  • analyse the refusal codes: a short message is associated with refusal codes to provide more details of the reason for the refusal
  • create alerts and/or trigger the 3DS according to your activity and users' regular behaviours, for example: if a first-time user is paying more than the average payment basket
  • per default, only allow pay-outs after 48 hours.
  • from 8PM to 8AM and weekends, try not to process or validate any pay-outs for clients who are not KYC approved and who request an amount exceeding a limit defined by you
Flag some types of behaviour, for instance:
  • flag pay-outs requested right after the transaction was completed
  • flag wallets that receive many refusal codes such as fraud codes, or 3DS failed codes
  • flag payments that are above your average payment basket
  • flag payments occurring too regularly by one same user over a day, a week or a month
  • flag a user who wants to register a new bank account: maybe set up a code confirmation system that asks for a cash-out of more than a certain amount (to be defined by you)
