Security for apps built with Cursor
Cursor helps you write code faster with AI. Faster code still needs the same scrutiny: AI can produce a missing authorization check or an exposed secret as easily as a human can. Start with a free external snapshot, then review what the outside view can't see.
AI-written code needs the same review as any code
Cursor is a genuine productivity boost, but it does not decide your app is secure. Generated code can skip an access-control check, trust input it shouldn't, or leave a secret in the repository, the same flaws any codebase can have, produced faster. The speed makes a security review more useful, not less.
The outside view can’t see this
Access control, input handling and secrets
The issues that cost real money live inside the code: an endpoint that returns another user's data because an ownership check is missing, input used unsafely in a query, or a credential committed to the repository. A passive external check can't see any of these, they need reading the code and testing the application, which is what a full review does.
What the free Surface Check covers for your Cursor app
- HTTPS and HSTS on your custom domain, so traffic can't be silently downgraded to plain HTTP.
- Security headers (Content-Security-Policy, clickjacking protection, nosniff) on your front-end.
- Your TLS certificate's health and how soon it expires.
- Cookie flags (HttpOnly, Secure, SameSite) on any session or auth cookies you set.
- Email spoofing: SPF, DKIM and DMARC on your domain, so attackers can't send email as you.

Is code written with Cursor less secure?
Not inherently, but it isn't automatically secure either. AI can introduce the same flaws a person can, faster, so the same review that any code deserves still applies.
What does the free check actually test?
Your public external surface only: headers, TLS, cookies and email/DNS. The deeper flaws (access control, input handling, secrets) live in the code and need a full review.
We move fast with Cursor. Does a review slow us down?
A Secvura review is designed for teams moving fast: a fixed price, a clear report scored by severity and fix effort, and the specific fix for each issue, so you can keep shipping.
Is the check free?
Yes, free and with no sign-up, with an A-to-F Surface Score and every issue scored by severity and fix effort.
