Stop wondering what's hitting your app.
Kriosa protects PHP and Laravel applications by blocking malicious requests in real time — and explaining exactly why each one was blocked.
Every request. Explained, not just logged.
This is a real excerpt from a Kriosa-protected app. No jargon, no raw stack traces — just what happened and why.
LIVE Attack Blocked — Real Proof
Built and tested with real applications.
Kriosa isn't a concept — it's already running in front of production PHP apps, including this site.
A production PHP application where developers Learn something. Teach something..
Knowledge from developers, for developers.
A PHP/MySQL design-proofing platform with client review workflows.
A production PHP application secured with Kriosa from day one.
Protect your PHP app in minutes.
One command, one config line, no rewrite.
Install
Add Kriosa to your project with Composer, or download kriosa.php directly — no dependencies either way.
Configure
Drop your API key into one line at the top of your entry file or .env.
Protect
Every request is checked from that point on. Nothing else in your app changes.
// Install via Composer
composer require kriosa-ai/kriosa-php
// Or include the file directly, no dependencies
require_once __DIR__ . '/kriosa.php';
// Initialize and protect
$kriosa = new Kriosa('sk_your_api_key');
if (!$kriosa->protect()) {
http_response_code(403);
die('Access Denied');
}How KRIOSA Works
KRIOSA sits between your application and clients, analyzing and protecting every request.
Request arrives
Every request to your app — form submission, login attempt, API call — passes through Kriosa first, before it reaches your code.
AI analyzes
Models trained on real attack data check the request for injection patterns, malformed input, and known abuse signatures — in under 10ms.
Decision explained
Clean requests pass straight through. Anything malicious is blocked, and the reason is written to your log in plain English.
What Kriosa protects against.
25+ attack vectors, checked on every request.
SQL Injection Attempts Protection
Real-time analysis of requests using machine learning models to identify malicious patterns before they reach your application.
XSS Attacks Protection
AI-powered detection blocks unknown attacks before they can harm your application
Command Inj. Detection
Structural and semantic validation of incoming requests to block malformed inputs and API abuse.
API Security
Protect your REST APIs from abuse, scraping, and malicious requests
Brute Force Attempts Protection
Intelligent rate limiting that adapts to traffic patterns and protects against brute force attacks.
Malicious Request Detection
Catches malformed and suspicious requests that don't match a known signature but still don't look right.
Security events, not marketing claims.
Live numbers from Kriosa-protected traffic.
