FlawPilot
Cursor scanner

Cursor wrote the code. Have you checked what it exposed?

AI pair programming ships fast. External security posture is a different question. FlawPilot scans your live app from the outside: 13 tools, fast results, no setup required.

The gap between fast shipping and secure shipping

Cursor makes you a faster developer. It doesn't make you a security team.

Cursor is a genuine productivity multiplier. Context-aware autocomplete, AI-generated functions, instant refactoring — if you're building with Cursor, you're shipping faster than you were before.

Speed is the benefit. The risk is that the same velocity that accelerates feature development also accelerates the accumulation of things worth reviewing: configuration decisions made under time pressure, third-party dependencies added by suggestion, API patterns that were clean in development and messier in production.

External security posture — what your app looks like from the public internet — is different from code quality. It includes your DNS configuration, TLS setup, HTTP security headers, email authentication records, and what services are exposed on what ports. These aren't things a code review catches. They're things an external scanner catches.

FlawPilot is that external scanner. It doesn't read your code. It does exactly what an attacker, a VC doing technical due diligence, or an enterprise security team would do: hit your production URL and see what comes back.

What Cursor left exposed

4
2 pillars
HighSecurity

DNS misconfiguration and subdomain takeover

Subdomain takeover risk, dangling CNAME records, and misconfigured nameservers. These don't show up in a linter - they show up in an external scan.

HighSecurity

Cloud storage exposed to the public

Public access on storage buckets. One misconfigured bucket can expose your entire data layer.

HighInfrastructure

Known CVEs in your exposed stack

Nuclei matches your exposed endpoints and headers against 50,000+ known CVE patterns, flagging known vulnerabilities in the frameworks and libraries your app exposes.

HighSecurity

Missing HTTP security headers

HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy. Missing headers are the most common finding across all app types.

A real scan surfaces these the way an attacker or enterprise customer would - before they do.

How it works

External scan. Real results. Fast.

One URL in, a plain-English report out. Every step is bounded and observable, so you always know where you are.

What we scan

What FlawPilot checks on every app

Cursor apps span a wide range of stacks: Next.js, FastAPI, Rails, Go, Node - depending on the developer's background. Our scan is stack-agnostic: we check what's externally visible regardless of what's underneath.

Vulnerability Signatures

Nuclei matches your exposed endpoints and headers against 50,000+ known CVE patterns. Flags known vulnerabilities in frameworks and libraries your tech stack exposes.

Security Headers

HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy. Missing headers are the most common finding across all app types.

TLS / SSL Configuration

Certificate validity, cipher suite strength, protocol version, mixed content. The full TLS picture.

Email Authentication (SPF, DMARC, DKIM)

Checks whether your domain is protected against spoofing. Missing DMARC means anyone can send email as your company.

Open Ports and Exposed Services

What's listening on the public internet that shouldn't be. Development ports, internal APIs, and admin interfaces that followed the app to production.

DNS Configuration and Subdomain Discovery

Subdomain takeover risk, dangling CNAME records, misconfigured nameservers.

CORS Configuration

Cross-origin policies. Overly permissive CORS is a frequent finding in apps where the API layer was added quickly.

S3 and Cloud Storage Exposure

Public access on storage buckets. One misconfigured bucket can expose your entire data layer.

WAF Presence

Whether a web application firewall is in front of your app.

Technology Stack Fingerprinting

What your app reveals about its underlying stack to anyone who looks.

Cookie and Session Security

Secure, HttpOnly, and SameSite flags. Session fixation and cookie theft risks.

HTTP Request Behavior

Redirect chains, HTTP to HTTPS enforcement, response header hygiene.

Frontend HTML Checks

Inline script patterns, sensitive data exposure in rendered source.

Two views, one scan

You're technical. Your customers have their own security team. One scan serves both.

Every finding is written twice. Flip the toggle on your report to read it as a founder or as the developer who'll fix it - same scan, same data, two registers.

Simple, business-friendly explanations.

Developer View (your default)

Founder view

CVSS severity scores, affected endpoints, Nuclei template IDs, tool attribution, and expandable technical findings. This is the view for you, the person who will actually fix what's found.

Questions about scanning Cursor-built apps

Code review and static analysis work from the inside. FlawPilot works from the outside: it scans what's visible on your live production URL, the same way an external attacker or enterprise security team would. Different vantage point, different findings. DNS misconfigurations, exposed ports, and missing security headers don't show up in a linter.

Cursor scanner

You ship fast. This check takes minutes.

External security posture is separate from code quality. FlawPilot gives you the outside-in view: what an attacker or enterprise customer sees when they hit your production URL.
