The basics
What are code audit services?
Code audit services are an independent review of your codebase that tells you what is slow, insecure or fragile, how risky each problem is and what it costs to fix. Ours pair AI-assisted analysis of the whole repository with a senior engineer who verifies every finding before it reaches the report.
A code audit is part technical debt assessment, part security code review and part application performance audit. You get one prioritized list instead of three opinions, and you can hand it to your own team or to ours.
It also works as technical due diligence: founders about to raise, sell or hire a CTO use the report to see the real state of the code before someone else does. For ColdFusion, PHP and Java systems the report adds a modernization path with options and costs.
Who needs code audit services?
Teams whose app got slower
Pages and queries have slowed down release by release, and nobody can say exactly why.
Founders before a raise or sale
You want an honest technical due diligence picture before investors or buyers ask for one.
New CTOs and tech leads
You inherited a codebase and need to know what is dangerous and what is merely old.
Owners of unmaintained systems
The original developers have gone and the system still runs part of the business.
A code audit is not a fit if…
- You need a SOC 2 report or a compliance certification. This is an engineering review, not a compliance audit.
- The code can't be shared read-only, or reviewing it would mean accessing patient health data (PHI).
- You want a rewrite quote without anyone looking at the code first.
Coverage
What do our code audit services cover?
Every code audit examines the same six areas, so you can compare risks across the whole system instead of fixing whatever is loudest this week.
Performance
The ten slowest endpoints and queries, measured, with the fix for each one.
Security
Known vulnerabilities, exposed secrets, outdated libraries and authentication weaknesses.
Dependencies
What is end-of-life, what is abandoned and what an upgrade would break.
Architecture
Where the complexity sits, and whether it needs to sit there.
Test coverage
What is protected by tests and what is one bad deploy away from an outage.
Developer experience
How long a new engineer needs to ship their first change, and what slows them down.
Timeline
How long do code audit services take?
A code audit takes 5–10 business days, depending on the size of the codebase. Your team spends about two hours: a kickoff, a few questions and the readout.
| Stage | What happens | What your team does |
|---|---|---|
| Kickoff | Scope agreed; read-only access to the repository and any performance monitoring | Join a short kickoff call and grant read-only access |
| Analysis | AI-assisted review of the whole codebase: performance, security, dependencies, architecture, tests | Answer a few quick questions |
| Senior review | A senior engineer verifies each finding, ranks it by risk and effort and prices the fix in days | Nothing, unless we hit a blocker |
| Readout | Written report and prioritized fix list; 45-minute readout with the engineer who did the work | Attend the readout and keep the report |
Report
What does each finding in the code audit report include?
Every finding is written the same way, so your team can sort the list, plan a sprint and start fixing without a second meeting.
| Field | What it tells you |
|---|---|
| The problem | What is wrong, in plain language, and where it lives in the code |
| Evidence | The measurement, scan result or code path that shows it |
| Risk | What happens if it stays: slowdowns, outages, data exposure or blocked upgrades |
| Effort | The fix, estimated in days |
| Priority | Where it sits in the fix list, weighing risk against effort |
| Recommended fix | The change we would make, so your team or ours can act on it |

Compare
Should you audit the code first or start fixing straight away?
Fixing straight away feels faster. A code audit costs less than spending a quarter on the wrong problems, or rewriting a system that only needed a few targeted fixes.
| Factor | Audit first | Start fixing straight away |
|---|---|---|
| Upfront cost | $1,000–$2,500, fixed | Weeks of engineer time |
| What gets fixed | Ranked by risk and effort | Whatever is loudest this week |
| Security | Known vulnerabilities and exposed secrets found deliberately | Found when something breaks |
| Rewrite decision | Based on evidence; rarely needed | Often made on frustration |
| Cost visibility | Every fix priced in days | Discovered as you go |
| What you keep | A report and fix list any team can use | Partial fixes and new unknowns |
Next steps
What happens after the code audit?
You choose. The report is written to be useful whether or not you work with us again.
Keep the report
Hand the prioritized fix list to your own team or any vendor. It is yours.
Fixed-price Fix Sprint
We fix the top items for a fixed price, usually $3,000–$7,500. See product development sprints.
Embedded engineer
A senior engineer works through the list inside your team, month to month. See staff augmentation services.
Why choose us
Why choose NorthPulse as your code audit company?
A good code audit company tells you what is dangerous and what is merely old, and prices both. Here is how our code audit services do that. See our security practices and case studies.
Senior engineers check every finding
AI speeds up the analysis; a senior engineer verifies each finding before it reaches your report.
Honest about rewrites
We almost never recommend a rewrite. The report separates dangerous code from old code.
Read-only access
We never need write access, and your code stays in your repositories.
Every fix priced
Each item in the fix list carries an estimate in days, so you can budget before you commit.
Fixed price, fixed timeline
$1,000–$2,500 by codebase size and 5–10 business days, agreed up front.
10+ years with legacy stacks
ColdFusion, PHP and Java systems get a modernization path with options and costs.

How much do code audit services cost?
Our code audit services cost $1,000 for up to 50k lines or one service, $1,750 for 50k–250k lines or 2–4 services, and $2,500 for larger or multi-repo codebases. The price is fixed before we start.
How long does a code audit take?
Five to ten business days from kickoff to readout, depending on the size of the codebase. Your team spends about two hours in total.
Do you need write access?
No. Read-only access to the repository and, if available, to performance monitoring.
Will you tell us to rewrite everything?
Almost never. The report separates what is dangerous from what is merely old, and prices each fix.
Is a code audit the same as a security audit?
It includes one. A code audit covers security alongside performance, dependencies, architecture, tests and developer experience, so you see every risk in one ranked list.
Can a code audit work as technical due diligence?
Yes. SaaS founders use the report before a seed or Series A raise, a sale or a CTO hire, to show the real state of the code, with a costed plan for what needs fixing.
Which languages and stacks do you audit?
Laravel/PHP, Node, Python, Java, Vue, React, Firebase, and ColdFusion or Lucee. ColdFusion, PHP and Java systems also get a modernization path.
Can you fix what you find?
Yes. Most audits lead to a fixed-price Fix Sprint ($3,000–$7,500) or an embedded engineer. You are free to take the list elsewhere.
How do I choose a code audit company?
Look for a fixed price, read-only access, findings verified by a senior engineer and a fix list priced in days. Be wary of an audit that ends in a sales pitch for a rewrite.
