What is SilentShield?

The difference
Visible CAPTCHA vs. invisible protection
Drag the slider: the usual CAPTCHA puzzle on the left, SilentShield on the right — same form, zero friction.
No puzzle for visitors
People fill in the form and send it. The check runs in the background, with no traffic lights or tick boxes.
Behavior instead of picture puzzles
SilentShield evaluates how a form is filled in and rates every visit as human, suspicious or bot.
No cookies, no tracking
The check sets no cookies and does not follow visitors across websites.

The privacy-friendly alternative to traditional CAPTCHAs – invisible, accessible, European.
Invisible
protects automatically, without disturbing users.
GDPR-compliant
built without cookies and without cross-site tracking.
Accessible
accessible for everyone, no barriers.
AI under control
decide per category what AI crawlers may do on your site.
Visible on request
invisible, a checkbox or a compact badge — the protection is identical.
AI traffic
Decide what AI does with your site
Every AI crawler that reaches your site shows up by name. You decide per category what it may do — not per bot, and not once and for all.
Allow
Your visibility in AI answers stays. Block AI search and you disappear from them.
Watch
Monitor mode is the default. Nothing is blocked until you switch enforcement on yourself.
Block
Training crawlers are turned away at your server, before they read a line.
