Precise Expressions Checkout Abuse Protection for WooCommerce helps mitigate automated checkout abuse and card-testing activity on WooCommerce stores.

This lightweight Lite version provides essential, always-on protection for both classic and block checkout without relying on third-party services.

It is designed to reduce automated pressure on checkout endpoints while remaining simple, privacy-aware, and low-overhead.

What the Lite Version Protects Against

Automated checkout submission bursts.
Repeated failed-payment retry attempts (common in card testing).
Unrealistically fast checkout submissions (timing signal).
Hidden field abuse via an invisible honeypot (classic checkout).
Excessive retries from a single IP.

The Lite version focuses on practical mitigation that store owners can enable quickly, without complex configuration.

Pro Version

A Pro add-on is available separately for stores that need detailed event logs, alerts, exports, and advanced reporting. The Lite version is fully functional on its own and does not require Pro.

Features (Lite Version)

Failed-payment retry throttling.

Privacy

This plugin:

Does not send data to third parties.
Stores aggregate blocked-attempt counts only (by day and reason) in the Lite version.
Does not store raw IP addresses in persistent logs.
Stores user-provided allowlist IPs exactly as entered in settings.

The Pro version stores structured event records for reporting purposes, without storing raw IP addresses or unnecessary personal data.
