Code Security Audit: A Continuous Source Code Audit | Nurbak

CODE SECURITY AUDIT

A code security audit that runs every day, not once a year

A classic security audit is a consulting engagement: weeks of scoping, a PDF report and a codebase that has already changed by the time you read it. Nurbak audits your source code continuously. Connect GitHub and get a 0 to 100 security score, findings with file, line and CWE, and fixes as pull requests.

Create account and connect GitHub

We never store your code. We only write when you ask for a fix PR.

Continuous, not annual

On a paid plan every repo is rescanned daily, so the audit keeps up with every merge instead of aging in a drawer.

Findings you can act on

Each issue comes with file, line, CWE and a plain-language explanation, not a generic checklist.

Not sent to OpenAI or Anthropic

The audit runs on Nurbak's own self-hosted model on ephemeral infrastructure.

Evidence you can keep

Every scan has a hash-chained audit trail you can download and verify.

What a code security audit covers

Authentication

Broken login and session logic, weak JWT handling and flawed password or token flows.

Access control

IDOR and missing authorization checks, where one user can read or change another user's data.

Injection and request forgery

SQL injection, XSS, SSTI, XXE, SSRF and CSRF, found by reasoning about how input flows through the code. See our vulnerability scanner.

Secrets

Hardcoded API keys, tokens and passwords, including those buried in git history.

Dependencies

Known CVEs in your third-party packages, checked against the OSV database.

CI and infrastructure as code

Misconfigurations in GitHub Actions, Dockerfiles, Terraform and Kubernetes manifests, plus CORS settings in the app.

What you get from each audit

A 0 to 100 security score

One number per repo that you can track over time and share with your team or your customers.

Findings with file, line and CWE

Every exploitable issue is pinned to the code and mapped to a CWE, explained in plain language.

Remediation as pull requests

One click opens a PR with the fix and a security regression test, so the issue stays fixed.

An audit trail for compliance

A hash-chained record of each scan, downloadable, that you can attach as evidence in your security reviews.

When you still need a human-led audit

Compliance attestations

A formal report or certification is issued by an independent auditor. Nurbak's findings and audit trail are useful evidence, not a substitute for that report.

Architecture and threat modeling

Deciding which threats matter for your business, and whether the design itself is sound, is still a job for experienced people.

Live systems and networks

Nurbak reads code. It does not scan networks or test running systems, so infrastructure and black-box testing need other tools or a pentest service.

How Nurbak audits your code

1

Create an account and connect GitHub. Public and private repos both work.

2

Pick a repo. Nurbak's own self-hosted model audits it on ephemeral infrastructure.

3

Get a 0 to 100 security score and findings with file, line, CWE and a plain-language explanation.

4

Open a pull request with the fix and a security regression test in one click.

5

On a paid plan the repo is rescanned daily, so new code is audited too.

Code security audit FAQ

What is a code security audit?

A code security audit, or source code audit, is a review of an application's code to find vulnerabilities an attacker could exploit: broken authentication and access control, injection, leaked secrets, vulnerable dependencies and insecure configuration. Unlike a black-box test, it looks at the source directly, so it sees logic that is invisible from outside. See also secure code review.

What is a cyber security audit, and where does a code audit fit?

A cyber security audit reviews an organization's security as a whole: policies, access management, infrastructure, networks and applications. A code security audit is the part focused on the software you build. Nurbak covers that part in depth. The rest of the audit needs other tools or an auditor.

What do security audit services usually include?

A typical engagement has scoping, a manual review by consultants, a report with findings and a retest weeks later. It is valuable but slow and quickly out of date. Nurbak automates the code part: the audit runs on every repo, is repeated daily on paid plans, and each fix arrives as a pull request. More on the continuous approach in automated penetration testing and AI pentest.

When do I still need a human-led security audit?

When you need a formal attestation or certification from an independent auditor, when you want an architecture review or threat modeling, and when you need live infrastructure or networks tested. Nurbak does not scan networks or exploit running systems. Its findings and hash-chained audit trail are good evidence to bring into those audits.

Which vulnerabilities does the audit find?

SQL injection, IDOR, SSRF, XSS, authentication and JWT flaws, CORS and CSRF issues, SSTI, XXE and hardcoded secrets, plus vulnerable dependencies, GitHub Actions, Docker, Terraform and Kubernetes misconfigurations, secrets in git history and critical code without tests. Our OWASP Top 10 2025 guide and our explainer on what penetration testing is give more context. For the broader picture, see application security testing.

Is my code sent to a third-party AI?

The analysis runs on Nurbak's own self-hosted model, so your code is not sent to OpenAI or Anthropic to be analyzed. The infrastructure is ephemeral and every scan has a hash-chained audit trail you can download. Only if you ask for a fix pull request and give explicit consent is the fix generated with Claude.

How much does it cost?

The first scan is free and shows the 3 most important findings in full, plus 1 free fix PR. Plans are USD 79 per month for 1 repo and USD 199 per month for up to 5 repos, with daily scans. Above 5 repos there is an Enterprise plan. See pricing.
