[Security & Legal](https://help.indiegraf.com/revengine?hsLang=en#security-legal) May 28, 2026 # How does News Revenue Engine protect against bad actors? ## Learn how RevEngine automatically flags and quarantines suspicious contributions to protect your organization from potential fraud. To preserve the security and stability of RevEngine, we use a service that automatically checks for potentially fraudulent contributions and *quarantines* them for review. Quarantined payments are not processed until they are reviewed and approved by our team. **Until approved, quarantined contributions:** - Are not processed by Stripe - Do not appear in your contributions dashboard - Do not generate a Slack notification - Are not visible in your contributor’s portal - Do not appear in downstream systems like Salesforce or Mailchimp ### **Why are some contributions quarantined?** Certain behaviors may lead to a contribution being flagged as possibly fraudulent and quarantined : - A would-be contributor makes many payment attempts in a short period of time for a given email or credit card number - Typos in the user’s address, name, or email - If contributions are made using emails with invalid / suspect patterns - Contributions of extremely high or low amounts *Please note that this list is not exhaustive, and other behaviors may also cause a contribution to be flagged.* Quarantined contributions usually have an empty Customer record in Stripe. For more details, see [this article](https://news-revenue-hub.atlassian.net/servicedesk/customer/article/3005022237?source=shareable-url). ### **What happens if a legitimate contribution gets quarantined?**  We expect that only a small number of your contributions may be incorrectly classified as fraudulent, which is why it's best to monitor for these cases. If a decision is not made on a payment within 72 hours, it’s automatically accepted. Once a payment is accepted, a receipt email is sent, and the payment appears in both your dashboard and the contributor’s portal. A charge is then created in Stripe, which initiates the payment processing. Keep in mind that Stripe has its own fraud prevention system. This means a payment might pass RevEngine’s fraud checks but still be flagged and rejected by Stripe as fraudulent. - [Welcome to Indiegraf](https://help.indiegraf.com/welcome-to-indiegraf?hsLang=en) -
