Frequently asked questions

What is SilentShield?

SilentShield is an invisible, GDPR-compliant CAPTCHA alternative that blocks bots on forms and logins without cookies, puzzles or data transfer to Google.

Is SilentShield really invisible?

Yes. Real users are verified in the background and never see a challenge; only clearly suspicious traffic may get an extra check.

Is SilentShield GDPR-compliant?

Yes. It sets no tracking cookies, stores only pseudonymised hashes, hosts data in the EU, and sends nothing to Google — unlike reCAPTCHA.

How do I add SilentShield to my site?

Add one script tag or install the WordPress plugin, then your forms are protected invisibly — usually in under 60 seconds.

How much does SilentShield cost?

There is a free plan for up to 500 requests per month; paid plans start at €9/month and scale with your volume, with no setup fees.
