Certificate validation, HSTS, CSP, and critical header analysis.
Sensitive File Leaks
Detect exposed .env, .git, backup files with API keys and passwords.
Open Port Scanning
Find exposed FTP, SSH, MySQL, and other risky open ports.
WordPress Recon
Username enumeration, plugin exposure, and xmlrpc.php detection.
GDPR & Compliance
Cookie security flags, blacklist checks, and regulatory readiness.
DNS & Reputation
SPF/DMARC records, subdomain discovery, and blacklist monitoring.
Export JSON / CSV
Download raw data for your IT team or paste into Cursor, ChatGPT, or any AI tool for instant fixes.
Technology Fingerprinting
Identify server software, frameworks, and CMS versions that may have known vulnerabilities.
Attack Surface Mapping
Visual network graph of your full external attack surface — subdomains, open ports, exposed files, WAF status, and SSL in one interactive map.
CORS & API Discovery
Detect CORS misconfigurations, exposed Swagger/OpenAPI docs, and publicly accessible API endpoints attackers can exploit.
Subdomain Takeover
Identify dangling CNAME records pointing to unclaimed cloud services — a critical hijacking risk most scanners miss.
Cloud Storage Exposure
Detect exposed AWS S3 buckets, Azure Blob containers, and Google Cloud Storage references leaked in your page source.
One-Click Copy Fix
Every vulnerability comes with a "Copy Fix" button and an "AI Fix Prompt" you can paste directly into ChatGPT, Cursor, or Claude for instant remediation code.
Interactive Security Dashboard
Severity distribution charts, category radar, score trend sparklines, and real-time scan step indicators — enterprise-grade visualization.

Common Questions
How does the React & Node.js Security Scanner work?
Modern JavaScript applications built with React, Next.js, Vue, and Node.js introduce unique security challenges. Client-side rendering exposes application logic, environment variables can leak through build processes, and the npm ecosystem's deep dependency trees create a massive attack surface.
AI QA Monkey performs external reconnaissance on your deployed app in under 60 seconds — analyzing SSL, security headers, exposed endpoints, CORS policies, and publicly accessible files.
Does it detect XSS and exposed .env files?
Developers frequently bypass React's built-in XSS protection using dangerouslySetInnerHTML. Next.js SSR apps face additional vectors through getServerSideProps data injection.
We check for publicly accessible .env files, exposed .git repositories, source map files (.js.map), and leaked API keys in client-side bundles prefixed with REACT_APP_ or NEXT_PUBLIC_.
Does it check API endpoints and CORS configuration?
We scan for exposed API routes, check CORS headers, detect open GraphQL endpoints, and identify server leaks. We also check for Node.js misconfigurations like exposed /debug, /status, and /metrics endpoints.
Common issues include Access-Control-Allow-Origin: *, enabled GraphQL introspection, and exposed Express.js error stack traces.
Understanding your JavaScript App Security Report
You receive a risk score from 0 to 100 with severity ratings and developer-friendly remediation steps. Export as JSON/CSV for your CI/CD pipeline, or download a PDF report. Premium reports include ready-to-use configs for Express.js, next.config.js, Vercel, and Netlify.
Live demo — 2 minutes
Attackers scan your site every day. Watch what they find — and how one report shuts them out.
A real site, a real scan: 27 hidden issues exposed in 60 seconds — exposed credentials, open database ports, spoofable email — then fixed the same day with the copy-paste code inside the $29 report, verified with free re-scans until the score climbs from 67 to 90, and sealed with a Verified Secure badge your visitors can see. The same recon a consultant bills $1,500+ for.
