A high risk payment gateway is often necessary for businesses that deal with high-risk transactions or have a higher likelihood of fraudulent activity. This particularly applies to online businesses, which usually process card-not-present transactions.
Some industries that often require high-risk payment gateways include:

  • Nutraceuticals or supplements
  • Online gambling or gaming
  • Adult entertainment
  • Travel

High-risk payment gateways specialize in managing the risks associated with these industries and can offer higher levels of fraud protection and security measures.
