Code Audit Services

A code audit that tells you what the codebase is actually hiding.

Most code audits are a scanner run against a checklist. We read the source itself — security, quality, architecture, dependencies, and the knowledge locked in a few people's heads — and hand you prioritized, reproducible evidence. Independent of the team that built it, and kept current as the code changes.

Beyond the code

A codebase is not a system.

The code tells you what exists. It can't tell you why it was built that way, who actually understands it, or whether it still does what it was meant to do. Those answers live in the commit history, the tickets, the PRDs, and the people who made the decisions — and that's where the real risk hides.

So we don't just scan the source. We audit the whole system: the code, the decisions that shaped it, and the knowledge holding it together. An off-the-shelf scanner hands you a thousand warnings and a score. We hand you the three findings that will actually cost you — in a breach, a failed deal, or a rewrite nobody budgeted for.

You leave understanding not just what your software is, but why it became that way — and what that means for what you do next.

What a source code audit covers

Six dimensions of the system.

01

Security Code Audit

Latent vulnerabilities and business-logic flaws that pattern scanners miss — found through deep structural analysis of the full codebase, not a sample, and reported as breach exposure you can act on.

02

Code Quality Audit

Complexity, duplication, and test-coverage gaps mapped against change frequency, so you see where quality problems are actually slowing delivery — not just where a linter complains.

03

Dependency & License Audit

Every declared and undeclared third-party dependency, with copyleft and AGPL license exposure (the kind that can force you to open-source your own code) and end-of-life packages flagged across your full package tree.

04

Architecture Review

The system topology as it's actually deployed — bottlenecks, single points of failure, and coupling that makes every change risky. The real architecture, not the diagram.

05

Technical Debt Hotspots

Change-driven prioritization surfaces the code that is both complex and frequently modified — where maintenance cost and defect risk concentrate.

06

Knowledge Concentration

Git-history analysis reveals which engineers hold unique expertise over critical modules. A bus factor of one on revenue-critical code is a finding, not a footnote.

How it works

Read-only. No disruption to your team.

01

Read-only access

We connect to your repository and CI/CD under NDA in an isolated environment. Nothing is modified; your team keeps shipping.

02

Automated analysis

Our tooling reads the whole codebase — every file, dependency, and the full commit history — and runs security, quality, and license analysis across all of it.

03

Prioritized findings

A consultant reviews and ranks the findings by business impact, then walks you through what to fix first and what it will take.

What you get

Findings you can act on.

Not a thousand-line scanner dump — a prioritized, evidence-backed picture of the codebase and what to do about it.

Key-person risk read: four buildup questions — ownership, criticality, concentration, and continuity — trace through the source evidence (commits, comments, PRDs, wiki, architecture docs) into an executive answer. Critical knowledge concentrates in 5 domains (Billing 84%, Identity/auth 78%, AI workflow layer 72%, Core intake 64%, Reporting 59%); 3 systems depend on a single owner and the top 4 engineers account for 72% of critical-path changes, with weak backup ownership and partial documentation flagged for immediate cross-training.

Common questions

Code audits, answered.

What is a code audit?

A code audit is a structured review of a codebase to assess its security, quality, architecture, and maintainability. A thorough audit reads the source, commit history, and dependency tree directly — surfacing vulnerabilities, technical debt, and license exposure as prioritized, reproducible findings rather than a generic score.

What's the difference between a security code audit and a code quality audit?

A security code audit targets vulnerabilities and business-logic flaws that expose you to attack or data loss. A code quality audit targets maintainability — complexity, duplication, coverage, and the debt hotspots that slow delivery. We run both as one source code audit because the same analysis surfaces both.

Will you change our code or disrupt the team?

No. Access is read-only and runs in an isolated environment. We don't commit, deploy, or touch your pipeline — your engineers keep working while we analyze.

Is a code audit the same as technical due diligence?

They share the same engine. A technical due diligence engagement frames the findings for an investor or acquirer evaluating a deal; a code audit frames them for the team that owns and operates the system. Same evidence, different audience.

Can you audit AI-generated code?

Yes — and it's increasingly the reason teams call. A large and growing share of code is now AI-generated, and studies consistently find AI-written code carries a higher rate of security vulnerabilities and accrues technical debt faster than human-authored code, because it ships fast without the architectural context a reviewer would supply. Our audit reads the codebase as it actually is, so it surfaces AI-introduced vulnerabilities, duplicated and low-context patterns, and the debt hotspots where "vibe-coded" velocity has outrun maintainability — before you acquire, invest, or scale on top of it.

Do you do independent, third-party code audits for an acquisition?

Yes. We're an independent firm with no stake in the outcome — we don't sell you the remediation, so the read isn't shaped by what we'd be paid to fix next. That makes our audit suited to a post-acquisition code audit, a read of a codebase you just inherited, or a third-party engineering review where the point is evidence a board or investment committee can rely on rather than the seller's or the in-house team's account.

Is a code audit the same as a software audit?

People use "software audit" for two different things: a license/compliance audit of which software you're entitled to run, and a technical audit of the source itself. We do the latter — reading the code, dependencies, and history to assess security, quality, architecture, and risk. If you mean a code-level read of a software asset's real condition, a code audit and a technical software audit are the same thing.

What We Are Not

We don't write code, manage your engineering team, or sell you a transformation roadmap. Our only interest is an accurate picture — which is exactly why you can trust it. What happens next is your decision, made with the right information for the first time.
