Everything you need to protect your website
SilentShield combines invisible bot protection with powerful analytics, team management, and GDPR-compliant use.
What does SilentShield do?
SilentShield is invisible bot protection that secures forms and logins without a CAPTCHA. It analyses behaviour in the browser, blocks bots automatically, and lets real users through with zero friction — GDPR-compliant, EU-hosted, in 25 languages.
How it works
Invisible detection in real time
Every request runs through behavioural analysis in the browser — no cross-site tracking, no image puzzle for real users.
Request
A visitor submits a form or hits a protected endpoint. SilentShield watches silently — with no visible CAPTCHA.
Under the hood
What a checkbox can’t see
A classic CAPTCHA checks a click. SilentShield scores dozens of behavioral signals — invisibly, in milliseconds.

The actual screens behind the promises — AI agent control, the agent report, and three ways to show the widget.

AI agent control
See which AI crawlers visit your site and decide per category what they may do — allow, watch or block. Recommendations included, so you never cut off your AI visibility by accident.
How the rules work
Agent report
Every bot that reached your site, with request counts, verification status and how often someone merely claimed to be them.
Read the report
Three ways to show it
Invisible by default, a reCAPTCHA-style checkbox, or a compact badge. The protection is identical — you choose what visitors see.
Compare the modesBot Protection & Detection
Invisible Bot Detection
AI-powered behavior analysis detects bots without interrupting real users. No image puzzles, no friction.
CAPTCHA Widget
Drop-in JavaScript widget with a server-side check. Three display modes — invisible, a reCAPTCHA-style checkbox, or a compact badge — plus your own brand colours and logo.
Rate Limiting & DDoS Protection
Per-IP and per-API-key rate limiting protects your endpoints. Automatic abuse detection blocks repeat offenders.
Custom Alert Rules
Define custom rules for suspicious behavior. Get notified via email, webhook, or Slack when thresholds are exceeded.
AI & Agent Control
Agent Gateway
See every AI agent that reaches your site — verified, unsigned, or merely claiming the name. Then decide per category what each may do. Web Bot Auth (RFC 9421) plus legacy detection, GDPR-friendly (hashes only), works without WordPress.
Agent Report
Every bot that reached your site, with request counts, verification status, and how often someone merely used its name. Spoofing shows up as its own number, not as the real bot misbehaving.
Rules per AI category
AI search, AI agents and AI training are three separate decisions. Allow, watch or block each one — with a recommendation, so you never cut yourself out of AI answers by accident.
Analytics & Insights
Behavior Analytics
Real-time dashboard shows all recorded interactions, risk scores, and bot vs. human classification for every request.
CSV Export
Download your user interactions as CSV — up to 90 days, with the dashboard's filters, without IP addresses.
Configurable Data Retention
Control how long behavior data is stored. Automatic cleanup based on your plan's retention period.
Management & Collaboration
Team Management
Invite team members with role-based access. Share API keys across your team with owner, admin, and member roles.
API Key Management
Create and manage multiple API keys per domain. Monitor usage, set alerts, and rotate keys without downtime.
Multi-Channel Notifications
Receive alerts via email, webhook, or Slack. Configure per-key notification rules and thresholds.
