Rohan was a one-person engineering team. The MVP shipped in five weeks. The investor demo was a hit. Three months later he hired a senior engineer. She opened the repo, found 40,000 lines, twelve different patterns for the same thing, no tests, and three files marked “TODO: figure out what this does”. She gave him a polite two-week notice.
Rescue Cursor code audit · AI code review service · security testing · UK
Cursor code audit for the Series A diligence call. That’s on Tuesday.
Two senior engineers read your Cursor codebase the way a senior hire would on day one: the twelve helpers Cursor wrote for the same fetch, the Supabase RLS that’s off on four of seven tables, the secrets pasted into a Composer chat. 5 days later, a fix list ranked Critical / High / Medium with sample code. £8K fixed.

(Why founders book the Cursor code audit)
Your Cursor codebase shipped fast. Now find out what’s missing before someone else does.
Cursor is a brilliant builder. It’s not a security platform. Across thirteen independent Cursor IDE audits, every codebase had at least three critical findings. The 5-day audit tells you which ones are in yours.

Rohan shipped in five weeks. Cursor wrote 80% of it. Then a senior hire opened the repo.
The seed lead asked one question: “Has anyone independent looked at this yet?” The honest answer was no. So we ran the 5-day audit. We found nineteen things. Six were critical: a SQL injection vector in a custom query helper, plaintext passwords logged to Sentry, no CSRF on mutations, no rate limit on auth, no test coverage, no audit log.
He had the written report on day six. Ten medium, three low, six critical, each ranked with sample code and an effort estimate. This page is for founders who’d rather know what’s in their Cursor codebase before the seed lead does.
5 days. Four assessments. One written report.
Same shape every audit. NDA Monday morning. Written report Friday afternoon. Hourly support during the run. Thirteen Cursor IDE audits done since 2024 on this exact cadence.
- 01
“I vibe-coded the auth layer in Cursor. Is it actually secure?”
OWASP Top-10 penetration test against your live app. Auth review (sessions, tokens, RLS, anon-key handling). Dependency audit. Secret scanning across repo and Git history.
- 02
“I have 200 users. The deck says 50,000. Will the code survive?”
Schema review, data-flow diagram, state-management audit. Webhook reliability check. Load and scale model at 10× current traffic. What breaks first lives in the runbook.
- 03
“A senior will open this codebase and refuse the offer.”
Static analysis, dead-code map, test-coverage report. Logging and observability audit. CI/CD pipeline review. Deploy-rollback path tested end to end.
- 04
“An enterprise prospect just sent a 60-page security questionnaire.”
SOC-2 readiness checklist + UK GDPR data handling. DPA template + sub-processor list. 30-page written report with severity-ranked fix list, sample code, and effort estimates.
THE 8 WE SEE IN 80% OF CODEBASES
Eight things we find in almost every Cursor audit
Patterns from thirteen independent Cursor audits. You can’t blame the tool. You can fix the gaps before someone else finds them.
12 patterns for the same job
Cursor generated 12 different ways to fetch a user. None agree. The refactor takes 3 days because nobody can find them all. Critical.
No review trail on AI code
Git blame says “Cursor”. No review comment, no test, no ADR. Why decisions were made is unrecoverable. Critical.
Type-coerced strings everywhere
Cursor preferred TypeScript any when the type was unclear. 38% of the codebase is any. Runtime errors caught by customers, not the compiler. Critical.
No audit log on any mutation
Who changed what, when, why? No record. The SOC-2 audit becomes a six-month panic. Critical.
Customer PII in client state
Full name, email, billing address loaded into React state, visible in browser dev tools to anyone logged in. High.
Postgres queries with no indexes
Customer-list queries take 14 seconds at 5K records. At 50K they time out. Today it’s fine. In three months it’s an outage. High.
Secrets committed to the repo
Stripe live key, OpenAI key, or SendGrid key in plain text in a .env that’s in Git history. No rate limit on the auth endpoints either. High.
Zero tests, no compliance pack
No unit, integration, or e2e tests. No SOC-2, DPA, or GDPR pack. The first enterprise customer asks, the deal stalls. Medium.

Issues found by day
Cursor wrote 80% of it. A senior hire opened the repo, found 40,000 lines and twelve patterns for the same thing, and gave a polite two-week notice. The audit found what I couldn’t see.

What founders actually ask about the audit
Pain-first, soft-second.
The honest answer: probably not yet, and that’s normal. Across 13 Cursor IDE audits, every codebase had at least three critical findings, an auth gap, a billing race condition, a tenant-isolation hole, or a missing audit log. Cursor is a brilliant builder. It’s not a security platform. The 5-day Cursor code audit tells you what’s missing, ranked by severity, with effort estimates.
No. Every founder we audit shipped fast with the tools that worked. We’re not judging your speed. We’re telling you what to fix before someone else finds it. The audit report is written for you, not against you. We’ve never named-and-shamed a client and we never will.
5 days of senior engineering attention on your codebase. An OWASP-grade penetration test against your live Cursor app. Architecture review. Load model at 10× current traffic. SOC-2 readiness checklist. UK GDPR and DPA pack. Code quality and test-coverage report. A 30-page written report with severity-ranked findings, sample code per finding, and effort estimates in GBP and engineering days. You can walk away after the audit. Most founders don’t, but the option is real.
No. The audit runs against a staging copy of your codebase and a separate environment for penetration testing. Your production stays untouched. Your customers don’t see a thing.
Yes. The Cursor code review report is written so your engineer can fix the findings without us. Every finding has sample code, an effort estimate, and a recommended pattern. About a third of our audited clients fix in-house. About a third use us for the critical fixes only. About a third move to a full rebuild. All three paths are fine. You decide on day six.
For most cases, yes. The audit doubles as a Series A technical due diligence pack: architecture diagram, six suggested ADRs, threat model, sub-processor list, SOC-2 readiness checklist, DPA template. Seed leads have read it on Friday and approved on Monday. Enterprise customers have used it to skip 70% of their security questionnaire. Full SOC-2 certification is a separate 8-12 week paperwork phase; we hand you the path.
Yes, before anything else. NDA signed inside 30 minutes via DocuSign. Mutual NDA template ready. We only need read-only repo access, never write access. Audit findings are encrypted at rest, accessible only to the four engineers on your project, and destroyed 90 days after handover unless you request longer retention.
Cursor is the builder. We’re an independent auditor. The audit you get from us is the one your acquirer’s CTO trusts because it isn’t coming from the company that built the tool. Our pen test goes against your live app, the dependencies you imported, the integrations you wired in, and the deploy infrastructure you chose. Different angle, different findings.
That’s the best time to book it. Founders who run the audit before the diligence call walk into the meeting with the report in hand. Round timelines shorten. The seed lead asks for the audit and you already have it. That’s the conversation we want you to have.
