Stop Bots. Keep the Humans.
Bot and abuse protection for your sites, apps, and APIs — a human verification widget, server-side confirmation on every submission, and rate limiting, wherever they're hosted. Drop it into any signup, login, or contact form.
One Widget, Every Sensitive Form
Human Verification Widget
A drop-in challenge for signup, login, password reset, and contact forms — checked server-side, not just in the browser.
Rate Limiting & IP Blocking
Cap how often an IP or account can hit a sensitive endpoint, and block the ones that don't stop.
Real-Time Security Logs
Every verification and block is logged as it happens, so you can see exactly what Shield stopped and when.
Multiple Projects
Protect more than one site or app from a single Shield account, each with its own rules and logs.
Custom Rate-Limit Rules
Define exactly which endpoints get limited and how aggressively, per project.
Webhooks & REST API
Get notified the moment Shield blocks something, or verify a submission server-side from your own backend.
Wherever Your Site Is Hosted
Create a Project
Register the site or app you want to protect — Shield works with any stack, not just ACBIZ-hosted sites.
Drop In the Widget
Add the verification widget to your signup, login, or contact form with a small snippet.
Confirm Server-Side
Your backend confirms each submission against Shield's API before accepting it — never trusting the browser alone.
Watch the Logs
See what got blocked in real time, and tune your rate-limit rules as you learn what "normal" traffic looks like.
