Best Free WooCommerce Fraud Prevention Plugins (2026): $0 Compared
Free WooCommerce Security Tools
Know exactly what the free tier covers
Compare TrustLens Free, FraudLabs Pro Micro and included gateway protection without counting paid features as free.
TrustLens Free is a candidate for local customer-history scoring and card-testing controls; FraudLabs Pro Micro is a candidate for cloud order validation within its eligibility limits. Also check the protection included with your payment account. This is a focused comparison of these options, not a claim that no other free fraud plugin exists.
Disclosure: Webstepper develops TrustLens. Source review: September 9, 2026. Feature statements below come from the linked product documentation; we have not run a comparative detection-rate benchmark. For paid tools and service alternatives, use the full fraud prevention plugin comparison.
What counts as free?
A permanent free tier, an eligibility-limited allowance, protection bundled with a paid payment service, and a temporary trial are different offers. Check the exact function and conditions instead of relying on the plugin’s download price.
The options considered here
TrustLens and FraudLabs Pro publish free starting points. Radar is considered separately because payment-account terms determine what is included. OPMC and CleanTalk are discussed below to explain why their paid products or trials should not be presented as equivalent free tiers.
Free-tier comparison
| Question | TrustLens Free | FraudLabs Pro Micro |
|---|---|---|
| Main role | Local customer history, scoring and card-testing detection | Remote transaction validation |
| Published free boundary | Detection modules included; advanced controls in Pro | 500 queries/month AND monthly sales below US$25,000 |
| Where to inspect results | WooCommerce customer/risk views | Integration and service validation results |
| Automatic action | Device lockouts and customer-rule automation are different capabilities | Micro includes limited validation-rule capacity; verify connector actions |
| Main implementation question | Are gateway signals and customer associations correct? | Are quota usage and unavailable-service behavior monitored? |
TrustLens Free: distinguish detection from account automation
TrustLens documents eight detection modules and store-local customer scoring. Its free card-testing controls can temporarily restrict a device. That is different from a Pro automation rule that takes an action against a customer account. The earlier blanket statement that the free tier never blocks anything was too broad.
Check the actual protection and release controls in your version. A family sharing a device or customers using the same network can produce related signals, so keep manual review and recovery available. Source: TrustLens feature list and changelog. The customer-account blocking guide covers that narrower distinction.
FraudLabs Pro Micro: check both eligibility limits
The current pricing page lists 500 monthly queries and monthly sales below US$25,000. These are joint conditions, not alternatives. A store below one limit can still exceed the other. Micro also lists five validation rules.
Monitor actual query consumption rather than assuming one query always equals one completed order. Confirm what your integration does when validation is unavailable or an allowance is exhausted; the pricing page alone does not establish whether checkout will continue or stop.

Stripe Radar: check what your account includes
Some Radar protection is included under qualifying Stripe payment-account terms, while other plans add paid features. This is not the same as a standalone free WooCommerce extension. Country, account and integration determine access. Check current Radar plan terms and your gateway settings rather than assuming every Stripe-powered checkout exposes the same controls.
The Radar and WooCommerce customer-history guide explains how to check which signals each layer receives.
Paid extensions and trials are separate choices
The OPMC Marketplace extension is a paid product. CleanTalk uses a trial followed by a paid anti-spam service. Both may fit a store’s needs, but neither should be represented as a permanent free service in this comparison.
Choose and test your free starting point
- Describe the incident: suspicious payment, repeated checkout attempts, return pattern or coupon misuse.
- Check which option receives the required evidence in its free tier.
- Use a staging store and approved sandbox events to test a risk case and a legitimate customer.
- Record the resulting warning, hold or block and how staff can release it.
- Monitor quota/service errors, false positives and manual review work after deployment.
Keep the gateway’s existing protection while evaluating additional tools. If two tools can change the same order status or block the same customer journey, define their responsibilities and test the combination before enabling broad automation.
What should decide the choice?
Choose the tool that closes a demonstrated gap within its free limits. Do not judge by the number of modules alone. A useful warning with a clear review process is more valuable than a block your team cannot explain or reverse.
Common questions
Does TrustLens Free automatically block customer accounts?
Do not confuse automated customer-account rules with temporary card-testing device restrictions. Consult the current free/Pro boundary for the action you need.
Is FraudLabs Pro free below 500 orders?
The published Micro conditions refer to queries and monthly sales eligibility. Check both and monitor the actual API usage.
Can I use two free tools together?
Potentially. Test the gateway, checkout and action rules together; separate feature lists do not establish compatibility.
Does a free plugin guarantee that fraud stops?
No. Measure confirmed incidents, false positives and the time needed to review them. A tool’s value depends on your deployment and response process.
