WordPress Plugin Features
Say goodbye to spam, abuse, and frustrating CAPTCHAs.
The ALTCHA WordPress plugin protects your website with modern, invisible security — keeping bots out while letting real users in.
Unlike traditional tools, ALTCHA works entirely inside WordPress with no external services, giving you:
- Full control of your data (GDPR-compliant, privacy-first)
- Seamless integration with any plugin or theme
- Better performance under load
Whether you run a blog, an online store, or a growing business site, ALTCHA is the easiest way to stay safe, fast, and compliant.
Request Interceptor – Works Everywhere
ALTCHA’s Request Interceptor ensures protection across all of WordPress — including plugins like WooCommerce, Elementor, and Gravity Forms — without relying on fragile hooks or filters.
Here’s how it works:
- It watches over form submissions and AJAX requests
- When a submission happens, it runs an automatic proof-of-work check
- If verified, a secure cookie is set to authorize the request
Only requests with a valid verification cookie are accepted.
The result? Reliable, plugin-agnostic protection that won’t break when your other plugins update.
Invisible Protection – Frictionless for Users
No more “click the traffic lights” puzzles.
With Invisible Protection, ALTCHA silently verifies visitors in the background — no interaction required.
- Protects all forms automatically, with zero setup changes
- Users won’t notice it’s there
- Keeps spam out without hurting conversions
Invisible protection is available with the Professional plan.
Under Attack Mode – Stay Online Under Pressure
Heavy bot traffic or sudden surges in real users can crash a WordPress site. ALTCHA’s Under Attack Mode keeps your site responsive and online, even under stress.
When enabled, every visitor passes through a one-time challenge page that runs a proof-of-work check. After that, a short-lived cookie keeps them verified, so their browsing is smooth and uninterrupted.
Real results: In our tests, WordPress without protection managed ~30 concurrent connections before it became unresponsive. With Under Attack Mode, the same setup handled ~150 concurrent connections — a 5x improvement — while blocking bot traffic.
Perfect for e-commerce sites, product launches, or any moment you need maximum uptime.
Analytics – See What’s Happening
ALTCHA comes with a built-in Analytics dashboard that gives you clear insight into what’s going on:
- Successful verifications
- Failed attempts
- Blocked requests
- Detailed request logs
This makes it easy to prove effectiveness, spot suspicious activity, and fine-tune your security.
Firewall – Block the Bad Actors
Keep control of who can access your site with ALTCHA’s built-in firewall:
- Block by IP address
- Block by country
- Block by User-Agent (browser/device identifier)
Whether it’s malicious bots or persistent attackers, you can stop them before they reach your content.
Rate Limits – Stop Abuse at Scale
Define how many requests or submissions a user can make within a set time window.
- Protect forms from spam floods
- Prevent brute-force attempts
- Keep your site responsive under load
Firewall and Rate Limiting are included in the Professional plan.
