We were a NoFraud customer for many years and stayed on through the transition to Wyllo AI. Unfortunately, the service declined after the rebrand — decision accuracy on orders was noticeably worse than what we'd come to expect, and we ultimately moved to another fraud-protection provider. The reason for this review, though, is what happened on the way out. While closing out our remaining open disputes, we deliberately set the app to test mode so we would not be charged for orders, keeping it installed only to retain access to the case management tools. Wyllo then reactivated our account to live mode without asking us. We learned of it from an email sent by a senior member of their customer success team after the fact, telling us their technology had detected that our services "may have been accidentally disabled" and had already re-enabled them. It was not disabled in error — it was off by our deliberate choice — and at no point before reactivating did anyone ask us whether the change was intentional. Orders were charged in the meantime. The money is not the point. The point is that a vendor changed our store's configuration and turned a billable service back on based on their own assumptions, informing us only after it was done. That is not how a trusted partner behaves. We have reported the incident to Shopify and uninstalled the app. If you use this app, watch your billing closely — especially if you ever pause or test-mode the service.

Outstanding Fraud Protection with Exceptional Results We've been selling online since 2006, and using this fraud protection platform has been one of the best operational improvements we've made. Since implementing it in 2020, we've seen a significantly higher percentage of verified transactions and approved orders while maintaining an extremely low number of manual reviews and chargeback requests. One of the biggest benefits has been the confidence it gives our team. Legitimate customers experience a smoother checkout process, and fraudulent transactions have been virtually eliminated. The system is accurate, reliable, and has dramatically reduced the amount of time our staff spends reviewing questionable orders. If you're looking for an e-commerce fraud solution that increases approvals while minimizing chargebacks and manual intervention, I highly recommend this platform. It's been an invaluable tool for our business and has helped protect our online store while supporting continued growth.

Wyllo has been a reliable fraud prevention solution for our Shopify store. The integration was straightforward, and it has helped us reduce fraudulent orders while keeping our review process efficient. Like any fraud tool, there are occasional cases that require manual review, but overall it has been a valuable addition to our operations and has saved our team time.

We've been using Wyllo (formerly NoFraud) for several years and have had a great experience. The platform has helped us reduce fraud and chargebacks while allowing legitimate orders to be approved with confidence, which has been a huge benefit for our team. The process is straightforward, easy to manage, and their support team has always been responsive and helpful whenever we've had questions or needed assistance. Having Wyllo handle fraud screening has allowed our customer service team to focus on taking care of customers instead of spending time manually reviewing high-risk orders. Overall, it's been a valuable tool for our business, and we would recommend it to other Shopify merchants looking for a reliable fraud prevention solution.

Wyllo has been such a valuable tool for our business. The data insights alone have prevented fraud and helped us to make informed decisions about return and shipping claim abusers. Pair those insights with a phenomenal team that actually listens and works proactively to protect your business and you’ve got yourself a solution that makes your job easier.

Wyllo/NoFraud has been great for our business. We have worked with the team there for a long time. We rely heavily on their platform with our Shopify ecomm purchases. Their technology has helped us reduce or potential losses. They are laos very quick to respond to question and/or needs.

We previously used another service for fraud protection and now have used NoFraud for about two years. I feel we get a slight edge with Wyllo (NoFraud) and have successfully had more orders pass. They are very receptive and responsive. I do wish the new dashboard showed the contact status, but I understand that's in the works, and in the meantime it is easy enough to switch to classic view. Overall, worthwhile to our luxury goods online store.

Wyllo (NoFraud) has been a standout addition to our ecommerce technology stack. Their platform gives us added confidence in every order we process, helping us protect the business while continuing to deliver the level of service our customers expect. The implementation was smooth, the Chargeback Guarantee brings meaningful peace of mind, and the visibility behind fraud decisions has been especially valuable. Instead of operating in a black box, we have clear insight into why an order is approved or declined. Their customer success team has also been excellent. When we need support, they are responsive, knowledgeable, and professional. Wyllo has been a strong partner for our company, and we would highly recommend them.

Any amount puts this listing above the review-data order, on the board and in Store management. Every amount and every click is printed in public. Paying also opens a private page for this listing – that is where the badge for your site, the share card and your deal live. Everything you can do here, including what money cannot buy and how to get this listing corrected or taken down.
Not ready to pay for anything? Take the badge – it shows this listing’s live rank on your own site, it is free, and it always was.
Claiming is free and it shows: the listing turns gold in every list – the same highlight a paid card carries – with a Claimed badge, in the exact place its reviews put it. It also earns the only followed link on this site: a claimed listing that has paid nothing links to its own website dofollow – a paid placement never does, because a link that was paid for is an ad. Claiming moves nothing.
