  • A foundation for smooth modernization, microservices migration, or re-architecture,
  • Insights into architecture improvements and integration opportunities.
What We Offer

Services We Provide

  • Code Security Audit

    To ensure your application is secure, a comprehensive code security audit that goes beyond surface-level checks is obligatory. Thus, we review critical security mechanisms:

    • auditing and logging,
    • input and data validation,
    • code obfuscation,
    • thread safety, session management,
    • serialization filtering,
    • communication channels,
    • input/output operations,
    • connection strings.

    During the source code security audit, we identify vulnerabilities including race conditions, buffer overflows, code injections, cross-site scripting (XSS), and encryption flaws, helping you close security gaps before they become risks.

  • Legacy Code & Architecture Review

    Outdated systems pose a risk. But before the modernization, we can help you audit code and assess monolithic applications as a foundation for microservice transitions, and recommend re-architecture strategies tailored to your business goals.

    We thoroughly analyze monolithic applications to identify areas of:

    • tight coupling,
    • redundant logic,
    • obsolete dependencies.

    Based on your business objectives, we recommend further cost-efficient and the most applicable modernization strategies. It could be refactoring, full re-architecture, or a phased migration to microservices.

    We also assess whether your system is ready for cloud environments and deliver a robust plan for a future-proof architecture. The architecture that supports scalability, agility, and long-term growth.

  • End-to-End Performance & Maintainability Check

    In the process of a comprehensive code audit, we examine how well your code performs under real-world conditions. You get a prioritized roadmap for fixing inefficiencies, improving modularity, and enhancing code readability:

    • a check for clear, descriptive variable names and meaningful code comments,
    • preparation of a well-maintained documentation,
    • evaluation of the use of frameworks and reusable components,
    • assessment of proper code splitting and portability across environments.

    Our team also reviews version control hygiene, exception-handling strategies, and the integration of linter tools to enforce coding standards and reduce technical debt.

Our Process

How We Work

01.

01. Planning & Scope Definition

The better we understand your goals and development context, the better we can select the proper code audit strategy. Whether you're aiming to modernize a legacy system, prepare for a cloud migration, or improve delivery speed, the plan, as well as the evaluation criteria, will differ.

02.

02. Environment & Codebase Preparation

Before diving into analysis, we prepare the codebase for audit by verifying that all relevant repositories and dependencies are accessible. We also gather and explore supporting documentation to understand the logic, architecture, and any known technical challenges.

03.

03. Code Analysis & Manual Review

A two-layer analysis, static and dynamic, detects bugs, security vulnerabilities, code smells, and complexity issues. Then, our senior engineers perform a manual review of critical areas, assessing architecture, design patterns, naming, modularity, and overall code health. In the end, we also check quality indicators like Cyclomatic Complexity and Maintainability Index, moving away from guesswork. In parallel with the code review, we examine the architecture for risks and inefficiencies and audit session management, input validation, serialization filters, and communication channels. All is to uncover vulnerabilities like XSS, injection flaws, or unsafe cryptographic practices, ensuring a 360-degree protection.

04.

04. Reporting & Recommendations

A structured code audit report is always backed up with a summary of findings, categorized issue lists, and recommendations on further actions. It could be targeted refactoring, updates, re-architecture, or development workflow improvements. We also suggest how to improve long-term KPIs to guarantee impeccable protection.

Value We Provide

01

Quality Excellence

Our Project Management (PMO), Business Analysis (BAO), and Quality Management (QMO) offices form an audit code of conduct according to the ISO 9001, ISO 27001, HIPAA, and GDPR standards, overseeing every project delivery stage. Together, they ensure confident planning, smooth development, and efficient deployment, removing team friction.

02

Shorter Timelines

Thanks to our AI Solution Accelerator™, automated testing, and static code analysis, we deliver high-quality results up to 30% faster than the industry average. In all stages of software code audit, our focus is always on precision, speed, and long-term business impact for your company.

03

Proven Expertise

We leverage the advanced static code analyzers and profilers to identify slow queries and bottlenecks, whether it’s a website code audit or PHP code auditing. To fine-tune performance and memory usage, we rely on potent tools like dotTrace and dotMemory, ensuring your system runs efficiently under real-world conditions.

04

KPI-Based Approach

Turning from guesswork to frameworks, our audits are driven by measurable code audit service indicators such as Cyclomatic Complexity and the Maintainability Index. We go beyond code-level metrics like cycle time, deployment frequency, and failure rates, turning audit insights into real operational gains.

FAQ

Frequently Asked Questions

  • What is a code quality audit, and why is it important?

    A code quality audit is an in-depth review of a software codebase. Its purpose is to evaluate how well the code does its job — how legible, consistent, and maintainable it is. The better the code, the better it works without technical debt, productivity issues. So the system remains scalable and secure as it grows.

  • How do you perform a code quality audit?

    Code quality audits typically combine several methods to ensure thorough analysis. The schema is the following.

    Coding audit software like SonarQube, Coverity, and ReSharper automatically scans source code to detect syntax errors, security vulnerabilities, and code smells. It’s the first step.

    Then, static analysis examines code, helping to identify unused variables and dead code via FindBugs, PMD, and CheckStyle. Dynamic analysis, unlike static one, runs the code and reveals runtime problems that appear in the process. It could be memory leaks, race conditions, and concurrency issues.

    Additionally, peer reviews come in handy. At that, other developers manually inspect code for readability, adherence to standards, and overall quality. All steps together ensure qualitative improvement.

  • What tools are best to audit code?

    Some of the best automatic apps include SonarQube, ESLint, Pylint, Checkstyle, and CodeClimate. They analyze code for bugs, complexity thresholds, and style violations. Plus, IDE-integrated tools and test coverage analyzers like JaCoCo or Istanbul are also handy and deliver deeper insights.

  • How can I identify and reduce technical debt through a code audit?

    Technical debt, like messy code, lack of tests, outdated libraries, or patchwork fixes, can be identified through automatic and manual checks. Furthermore, the uncovered debt is managed and eliminated by code refactoring, simplifying logic, improving tests, and implementing better development practices.

  • What are the common issues found during a code quality audit?

    Common issues of poor code include inconsistent naming, high code complexity, duplicates, tightly coupled components, lack of documentation or tests, performance bottlenecks, and unaddressed security concerns. These problems typically result from rushed development, poor planning, or a lack of proper code review processes.
