Quick Scan: 40+ Security Checks in Under 3 Minutes

Quick Scan is the fastest way to find security vulnerabilities in your deployed web app. It runs 40+ automated checks in under 3 minutes, no account required. Paste a URL, get results.

You just finished building with Cursor, deployed to Vercel, and you're about to share the link. But are your API keys sitting in the JavaScript bundle? Is your CORS policy letting any domain read your API responses? Quick Scan answers these questions before an attacker does.

What Quick Scan Does

Quick Scan runs 40+ automated security scanners against your deployed application from the outside — exactly like an attacker would. It sends safe, read-only probes to detect misconfigurations and vulnerabilities without modifying any data on your server.

It's a fast first pass that catches obvious and critical issues before a deeper audit.

What It Checks

Critical & High Severity

• Exposed secrets — API keys for OpenAI, Stripe, AWS, Supabase, and 20+ services leaked in your JavaScript bundle
• XSS vulnerabilities — reflected and stored cross-site scripting in forms, URL parameters, and API responses
• JWT security — weak HMAC secrets, algorithm confusion attacks, sensitive data in token payloads
• OAuth2 misconfigurations — implicit flow usage, missing PKCE, exposed client secrets, open redirect_uri
• CSRF protection — missing tokens in forms, no Origin validation, SameSite cookie analysis
• IDOR / access control — ID enumeration on API endpoints, missing authorization checks
• NoSQL injection — MongoDB operator injection, authentication bypass patterns
• Race conditions — concurrent request testing on payment and reward endpoints

Medium & Low Severity

• Transport security — SSL/TLS configuration, missing HSTS, certificate issues
• Security headers — Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy
• CORS policy — overly permissive origins, credential exposure
• Email security — SPF, DMARC, DKIM record analysis
• Information disclosure — exposed .env files, .git directories, debug endpoints, stack traces
• Client-side storage — tokens and secrets stored in localStorage or sessionStorage
• WebSocket security — unauthenticated access, origin spoofing
• Rate limiting — missing rate limits on authentication endpoints
• Dependency audit — known CVEs in JavaScript libraries loaded by your app
• Supabase & Firebase — misconfigured RLS policies, exposed service keys, open storage buckets

What Quick Scan Skips

Quick Scan intentionally skips scanners that are slow, require browser automation, or send heavy probe traffic:

• SQL injection — time-based and blind SQLi testing requires many requests
• SSRF — cloud metadata probes and internal service access tests
• Command injection — OS-level RCE detection
• Server-side template injection — SSTI in rendering engines
• Database port scanning — TCP probes for exposed MySQL, PostgreSQL, MongoDB, Redis
• Subdomain takeover — dangling CNAME analysis
• DNS intelligence — zone transfer attacks, DNSSEC analysis
• Browser CDP session — headless Chromium for runtime JS analysis
• AI analysis — attack chain detection, fix prompt generation, business logic abuse

These are all included in Deep Scan.

Who It's For

• Pre-launch sanity check — paste your URL before sharing it publicly
• CI/CD integration — run after every deployment, fail the pipeline on critical findings
• Quick comparison — scan multiple apps in minutes to prioritize which needs a deeper audit
• First-time users — no account, no credit card, instant results

How to Use It

1. Go to vibewshield.com/scan
2. Paste your deployed app URL
3. Confirm you own or are authorized to test the target
4. Click Execute
5. Results appear in ~3 minutes

Frequently Asked Questions

Is Quick Scan really free? Yes. No account, no credit card, no limits on the number of apps you scan (subject to rate limiting to prevent abuse).

Will it break my app? No. Quick Scan only sends safe, read-only requests. It never uploads files, modifies data, or sends destructive payloads.

What if Quick Scan finds something critical? Fix it immediately. Each finding includes the severity level, affected endpoint, and evidence. For AI-generated fix prompts and deeper analysis, run a Deep Scan.

How is it different from Deep Scan? Quick Scan runs 40+ scanners in ~3 minutes. Deep Scan runs all 54+ scanners including SQL injection, SSRF, browser analysis, and AI-powered attack chain detection in ~10 minutes. Read more about Deep Scan →
