What Is Secure Code Review?

Secure code review is a structured manual + tooling-assisted analysis of your application source code by certified experts. Unlike pen testing (runtime, black-box), code review is white-box — it finds latent issues in auth flows, crypto, deserialization, and business logic that may not even be reachable in production yet. Required for PCI DSS Req 6.2, ISO 27001 Annex A.8.28, and OWASP ASVS verification.

Beyond scanner output

Tools surface candidates. Manual review confirms, exploits, and writes the fix.

Auth & Authorisation

Crypto Usage

Algorithm choice, key handling, IV reuse, hash usage, cert validation, RNG quality

Input Validation

Injection sinks (SQL, NoSQL, command, LDAP, template), deserialization, XXE, XSS

Business Logic

State machines, race conditions, idempotency, transaction integrity, multi-step flows

Supply Chain

Lockfile audit, transitive CVEs, license compliance, package-source verification

IaC + CI/CD

Terraform / CloudFormation / Bicep, pipeline secrets, runner trust, image signing

Secret Management

Hard-coded secrets, env-var leakage, log scrubbing, KMS / vault integration

Error Handling

Stack trace leakage, fail-open patterns, exception masking, debug-mode in prod

Methodology

9 steps. Every line that matters.

Every engagement runs through Lemon, our audit-management platform — informed by 6,700+ prior assessments and consistent across the team that delivers it.

Discovery

Repo Onboarding & Threat Model

Read-only repo access, scope confirmation, key flow identification (auth, payments, PII handling, admin paths). Lemon ingests the codebase shape and prior-engagement context.

Dependency & Supply-Chain Audit

Lockfile review, known-CVE mapping, outdated runtime detection, license compliance. Flag risky transitive dependencies and unverified package sources.

SAST + Manual Triage

Multi-tool SAST baseline (language-appropriate), AI-assisted triage to remove false positives, manual review of every flagged finding before it ever appears in a report.

Testing

Targeted Manual Review

Auth flows, authorisation boundaries, crypto usage, input validation, error/exception handling, secret management, deserialization. Where the high-impact bugs hide.

Business-Logic Walkthrough

Trace key user journeys end-to-end through the code. Look for state machines, race conditions, transaction integrity, multi-step authorisation gaps, idempotency.

IaC + CI/CD Review

Terraform / CloudFormation / Bicep, GitHub Actions / GitLab CI / Jenkins pipelines, container Dockerfiles, secret-scanning gaps. Pipeline supply-chain security.

AI-Augmented Cross-Check

AI cross-references manual findings, scanner output, and prior code-review patterns to surface missed sinks and untested code paths before delivery.

Delivery

Three-Layer QA Review

L1 code reviewer → L2 senior consultant → L3 security architect. Every finding validated, every reproduction reviewed, every CVSS scored consistently.

Reporting & Re-test

Executive + technical reports with code-level fixes (not vague advice), retest after remediation, and security assessment certificate.

Compliance-Ready

Audit-ready reporting for code mandates

Code review reports satisfy the secure-development clauses your auditor will check — PCI DSS 6.2, ISO 27001 A.8.28, OWASP ASVS, NIST SSDF.

Common engagement scopes

What clients ask us to review

Code engagements cluster into a handful of well-defined patterns — each sized by LOC and language complexity. Lemon tracks LOC-progress against budget daily.

Pre-launch SaaS / Series-B audit Full-stack review + supply chain

Payment SDK / module Crypto, key handling, transaction integrity

BFSI core service review Auth, audit log, idempotency, replay

Data-engineering pipeline Spark/Airflow/dbt — secret + access posture

Mobile SDK / library audit White-box pair to pen test of consumer app

IaC + CI/CD only Pipeline supply-chain, runner trust, secrets

FAQ

Common questions

Can\'t find what you\'re looking for? Talk to our code-review lead.

What is secure code review? +

Secure code review is a structured manual + tooling-assisted analysis of your application source code by certified experts to find security defects before they ship. Unlike pen testing (black-box, runtime), code review is white-box and finds latent issues — auth gaps, crypto mistakes, deserialization, race conditions — that may not be reachable in production yet but are reachable next release.

Which languages do you cover? +

Java, Kotlin, Python, Node.js / TypeScript, .NET (C#, VB), Go, Rust, PHP, Ruby, Swift, Dart, Scala. Plus IaC (Terraform, CloudFormation, Bicep, Pulumi), CI configs (GitHub Actions, GitLab CI, Jenkins), and Dockerfiles. We assemble language-specific reviewers per engagement.

How does code review compare to SAST? +

SAST is one input, not the answer. Tools generate signal AND noise — typically 60–80% false positive on first pass. Our value is the human triage and manual review that turns scanner output into validated findings, plus the manual deep-dive into business logic and crypto that no tool understands.

Repo access — what do you need? +

Read-only access to a frozen branch / tag, ideally via a federated SSO grant scoped to our auditors. We sign mutual NDA before access. We can review on-prem in your environment for highly-sensitive codebases (defence, central-bank, classified). Code never leaves your boundary unless you authorise.

How does pricing scale with codebase size? +

Effort is roughly per LOC (lines of code), modulated by language complexity and depth. Typical Node.js + React app of 80K LOC: 8–12 reviewer-days. Java enterprise monolith of 400K LOC: 20–35 days. Pure IaC + pipeline review: 3–5 days. Lemon tracks LOC progress against budget daily.

Do you cover supply-chain (dependencies, transitives)? +

Yes — lockfile audit, known-CVE mapping across direct and transitive deps, license compliance, package-source verification. We flag dependency-confusion, typosquatting, and unmaintained packages. Modern attacks come through your dependencies more often than your own code.

How long does a code review take? +

Scoped per LOC + language. Single-service / microservice (under 50K LOC): 5–8 business days. Enterprise monolith: 15–35 days. Lemon enforces daily progress tracking against the budget so there are no surprises at the end.

Do you provide remediation guidance? +

Yes — reports include exact code-level fixes in the language being reviewed (Swift, Kotlin, Java, Python, etc.), not vague advice. We also offer a walkthrough call with your engineering team and retest rounds after remediation.
