Prevent fundraising fraud before it occurs

Nonprofit donation forms are common targets for ‘card testing’ — automated attacks where criminals run stolen card numbers through donation forms in small amounts to verify the cards work, then resell the working cards. Without fraud protection, this drives chargebacks, processor fees, and damage to your Stripe account standing. Fundraise Up’s fraud detection system blocks these attacks before they process.

Fundraise Up’s AI-powered fraud detection system analyzes device characteristics, browsing behavior, and transaction patterns across millions of donations to identify suspicious signals in real time. It flags behavioral anomalies, mismatches between a donor’s geolocation and card-issuing country, and proxy or VPN use without adding any friction for legitimate donors. Suspicious transactions are routed to our in-house fraud-prevention team for human review before any action is taken. It’s fraud protection built into your nonprofit fundraising software that runs continuously in the background on every transaction.

Flagged transactions are reviewed by Fundraise Up’s in-house fraud-prevention team, not held indefinitely or auto-rejected. The team determines whether the donation should be processed or blocked, and legitimate donors are never penalized for triggering a suspicious signal. This combination of automated detection and human oversight is what allows Fundraise Up to block 98.8% of fraudulent attempts while keeping genuine donors moving through checkout. For nonprofits, it means your fundraising software is catching fraud without slowing down the giving experience.

No. Fraud detection happens in the background and adds no friction for legitimate donors. The vast majority of donations process normally through Fundraise Up’s online fundraising platform, and only suspicious transactions are routed for review. Customers like UNICEF USA and International Justice Mission UK process high volumes of donations with strong fraud protection and conversion optimization running simultaneously. Every donation form benefits from the same level of protection, regardless of traffic volume.

Fraud protection is included with Fundraise Up at no additional cost. It’s part of the core platform, not a paid add-on. Every Fundraise Up customer gets enterprise-grade fraud protection from day one regardless of size.
