Is your Gemini-built app production-ready?

Platform-aware security audit for apps built with Google Gemini and Gemini Code Assist. What it covers, what it typically finds, and how to run one in 30 seconds.

OWASP Top 10CWE Top 25CVSS v3CVE scanning

TL;DR: Gemini generates capable full-stack code, but like every code assistant it leaves production hardening to you. The gaps we see most: authorization checks skipped on protected routes, no rate limiting, and secrets handled loosely. Free scan: launchreadycode.com.

Works on any web app — not just Gemini builds. The scanner tests your live URL regardless of what generated it; the patterns below are simply what we see most in Gemini projects.

What a Gemini security audit covers

Every Gemini audit covers four dimensions — the same four we check on any live app. For Gemini builds specifically, Security and Monitoring are where the most actionable findings concentrate.

1. Security (highest risk for Gemini apps)

Authorization gaps: protected routes and data access generated without ownership/role checks — one user can reach another’s data (IDOR/BOLA). OWASP A01:2021, CWE-639.
Rate limiting: auth and AI-backed endpoints generated without throttling. OWASP A04:2021.
Secret management: API keys inlined or committed rather than loaded from a secret store. CWE-312.
HTTP security headers: CSP, X-Frame-Options, X-Content-Type-Options, HSTS — unset unless explicitly added.
Dependency CVEs: versions chosen at generation time may carry known vulnerabilities. CWE-1395.

2. Reliability

Uncaught exceptions exposing stack traces or internal file paths to end users
Unhandled promise rejections in async operations that can crash the server
No graceful degradation when a third-party service (payments, LLM API, database) is down
Race conditions in concurrent operations

3. Performance

N+1 query patterns that work at 100 users and fail at 10,000
Missing indexes on frequently filtered or joined columns
Synchronous blocking work on the event loop
Oversized client bundles from unused imports

4. Monitoring

Error tracking absent — you learn about failures from users, not alerts
No uptime monitoring configured
No alerting on auth anomalies or payment failures
No structured logging for production incident debugging

Gemini-specific patterns we check

Gemini produces clean, working scaffolds; the gaps concentrate in access control and the operational layer (throttling, secrets, observability) that a generator can’t infer.

The three issues we find most often in Gemini-built apps: (1) missing authorization / object-level access checks; (2) no rate limiting on sensitive endpoints; (3) secrets inlined or committed.

None of these are flaws in Gemini itself — they are standard production-hardening steps that require explicit decisions after code generation.

What an LRC Gemini audit finds, in numbers

Based on AI-built apps scanned through launchreadycode.com and published research:

45%

of AI-written code ships with a security flaw (Veracode, 2025)

78%

of AI-built apps we scan have HTTP security headers unconfigured

dimensions checked: security, reliability, performance, monitoring

How to run a Gemini security audit

Option 1 — Free scan (URL-based, 30 seconds)

Paste your live URL at launchreadycode.com. No code access, no signup. You get a Launch Readiness Score /100 across all four dimensions plus the top findings.

Option 2 — Full audit report ($499 one-time)

The Launch Readiness Audit Report covers every finding with CVSS v3 severity, file references where applicable, and specific recommended fixes — delivered in under 2 minutes.

Option 3 — Prove it with a real pen test (Exploit Proof)

A scan finds where you're weak. Exploit Proof tries to actually break in — an authorized 72-hour penetration test where you pay $297 only if we confirm a breach, and $0 (plus a signed certificate) if we can't.

Pre-launch security checklist for Gemini apps

Run npm audit (or pip-audit) and resolve all high/critical CVEs; enable automated dependency scanning.
Add rate-limiting middleware on every auth route and any AI-backed or payment endpoint.
Configure error tracking (e.g. Sentry) and wire it to production before go-live.
Set HTTP security headers: Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security.
Add CSRF protection on every state-changing route.
Audit environment variables — confirm no secret appears in client-side code or version-control history.

Frequently asked questions

Is Google Gemini code secure?

Gemini produces functional full-stack code, but independent research (Veracode, 2025) found ~45% of AI-generated code introduces a security vulnerability. The gaps we see are authorization, rate limiting, and secret hygiene — all standard hardening steps, fixable once identified.

What does a Gemini security audit check?

Four dimensions: Security (authorization/IDOR, rate limiting, secrets, headers, CVEs), Reliability, Performance, and Monitoring. Methodology: OWASP Top 10, CWE Top 25, CVSS v3.

Do you need code access?

No. The scanner is URL-based and tests your live app from the outside, where attackers start. Paste the URL and get a score in 30 seconds.

How much does it cost?

Free Launch Readiness Score at launchreadycode.com; full report $499 one-time; monitoring from $149/month. Exploit Proof adds a real 72-hour pen test billed at $297 only on a confirmed breach.

How is this different from a Lovable or Cursor audit?

The four dimensions and methodology are identical — the platform-specific checks differ. See also: ChatGPT / Codex security audit · Claude Code security audit.
