SilentShield is an invisible, GDPR-compliant CAPTCHA alternative that stops spam and fake orders in WooCommerce. It hooks into checkout, login, registration and review forms and verifies each submission with a single API key — no cookies or cross-site tracking. Hosting is in the EU by default and forms stay accessible under WCAG 2.1 AA.

How SilentShield protects WooCommerce
SilentShield adds an invisible verification to your WooCommerce forms and checks every submission in the background. It connects to the standard WooCommerce form hooks for checkout, customer login, account registration and product reviews. Genuine customers never see a puzzle, while automated spam and fake orders are blocked before they reach your store.
Stops fake orders and spam reviews
Bots often place fraudulent orders, create fake accounts and post spam reviews that distort your store. SilentShield verifies each of these actions using one API key, so only real customers get through. Because the check is invisible, it protects revenue and review quality without adding friction to the shopping journey.
Setup walkthrough
Add the SilentShield client script to your store and copy your API key from the dashboard. The protection attaches to the WooCommerce checkout, login, registration and review forms through their standard hooks, and each submission is verified on your backend. After saving, protected forms are checked automatically for every visitor.
Privacy and accessibility by default
SilentShield uses no cookies and no cross-site tracking; the IP address is used only for the check and is not stored in plain text. This lets you protect your checkout in a GDPR-compliant way. Verification runs on our servers in Germany by default. The invisible approach meets WCAG 2.1 AA, so customers using assistive technology can complete an order without solving image or audio challenges.

Frequently asked questions
How do I stop spam on WooCommerce?
Use SilentShield to protect WooCommerce checkout, account and review forms from bots. The SilentShield WordPress plugin supports WooCommerce directly — install it, add your single API key, and forms are verified invisibly through behavioral signals and a proof-of-work nonce, with no image puzzles for shoppers.
Does SilentShield work with WooCommerce?
Yes. The plugin was tested for WooCommerce checkout (classic) and WooCommerce checkout (block checkout) (checked on October 7, 2026 with plugin 2.15.14 and WordPress 7.1.2). You install the plugin once, add your API key and switch on the checkout under “SilentShield → Forms” — no separate CAPTCHA widget and no cookies for the bot check.
Can SilentShield stop fake accounts and review spam on WooCommerce?
Yes. SilentShield defends WooCommerce registration, login and review forms against fake-account and spam bots. It scores behavioral signals in the browser and verifies a proof-of-work nonce on your backend, blocking automated abuse while genuine shoppers submit normally without solving a puzzle.
Is SilentShield GDPR-compliant for WooCommerce?
Yes. Like every SilentShield plan, WooCommerce protection keeps data on our servers in Germany, sets no cookies, does no cross-site tracking and stores the IP address only as a hash. Whether you need consent depends on the mode: in Zero-PII mode the widget does without fingerprint characteristics (canvas, WebGL, audio). reCAPTCHA, by contrast, loads scripts from Google.
Does spam protection slow down WooCommerce checkout?
Hardly. SilentShield loads a client script of about 49 KB (gzip, measured on 23 Sep 2026) with no image assets. Verification uses behavioural signals and a proof-of-work nonce with no third-party tracking calls.
Do WooCommerce customers see a CAPTCHA?
Not in the default mode. The plugin embeds the SilentShield widget, which verifies real shoppers in the background through behavioural signals and a proof-of-work nonce; only when the result is unclear is there a short arithmetic task. The widget is tested against WCAG 2.1 AA.
