How much does a security audit of an AI-built app cost?

David He, FounderUpdated 3 min read
The short answer

A founder-sized review of an AI-built app costs about $500 to $3,000. A full code audit from a firm runs about $5,000 to $10,000 or more, a penetration test usually starts around $5,000, and a SOC 2 program can cost $20,000 to $60,000 in its first year. NexAI's AI app audit is from $500.

Four different products

People say "security audit" for four different things. Knowing which one you need saves thousands.

What it isTypical costWhen you need it
Founder-sized review of an AI-built appabout $500 to $3,000before launch, before showing investors, after a scare
Full code audit (architecture, security, quality)about $5,000 to $10,000+before a raise or acquisition, or when a new team inherits the code
Penetration testusually from about $5,000when a customer or insurer asks for one
SOC 2 programabout $20,000 to $60,000 in year onewhen enterprise customers require it

Prices are from published rate cards and guides in 2026. They vary with how big your app is.

What drives the price

  • Size of the codebase. A small MVP takes a reviewer a day or two. A large platform takes weeks.
  • How much is checked by hand. Automated scans are cheap. A person reading your access rules and permission checks costs more and finds more.
  • Whether fixes are included. Some reviews hand you a list. Others fix the worst problems for you.
  • Paperwork. A report written for an auditor or an enterprise buyer takes longer than one written for you.

What a good founder review should give you

  • A ranked list of problems, worst first, in plain English.
  • For each one, how to reproduce it and how to fix it.
  • A clear answer on whether it is safe to launch now, and what must change first.
  • A short call to walk through it.

If a report is a 60-page export from a scanning tool, you paid for the tool, not the review.

Which one do you need right now?

  • Pre-launch, no customers yet: a founder-sized review.
  • First paying customers, holding their data: a founder-sized review now, and again after big changes.
  • An enterprise prospect sent a security questionnaire: start with a review, then a pen test if they ask for one by name.
  • Raising money or selling the company: a full code audit.

What NexAI charges

The AI app audit is $500 working session · $1,500 to $2,500 full 6-pass repo audit · $4,500 to $8,000 hardening sprint. Turnaround: written audit report within 24 hours. I review what shipped, write the plan that makes it safe, and either hand you the plan or take it to production myself.

More questions founders with ai-built apps ask

How much does a code audit cost for a startup?

A founder-sized review of a small AI-built app is about $500 to $3,000. A full audit from a firm usually runs $5,000 to $10,000 or more, depending on the size of the codebase.

Do I need a penetration test before launch?

Usually not. Most early apps need a review of access rules, secrets and permission checks first. Get a pen test when a customer, partner or insurer asks for one.

Is a cheap automated scan enough?

It is a good first step, not the whole job. Scanners miss business-logic bugs, such as one user being able to open another user's records, which cause the worst leaks.
