Carried out by a joint team of senior developers and security experts, software code audit implies a combination of automated techniques and manual code analysis to provide a holistic view of code quality and security.

Who Can Benefit from Our Code Audit

Corporate software customers

  • Evaluate the quality of the software you are planning to invest in.
  • Enhance the performance of custom or platform-based solutions currently in use.
  • Prevent security and compliance breaches caused by source code issues.
  • Ensure code consistency in case of contracting a new team of developers.

What We Check within Our Code Audit

Code security audit

To assess code security, we:

  • Check security mechanisms and properties, such as auditing and logging, input/data validation, code obfuscation, code thread safety, serialization filtering, session management, and more.
  • Evaluate the security of communication, input/output operations, connection strings.
  • Reveal race condition, buffer overflow, code injection and cross-site scripting (XSS) vulnerabilities and encryption errors.

All-around code audit

In addition to code security, we evaluate the code against best coding practices. We check:

  • Descriptive names for code variables.
  • Code comments and documentation.
  • Utilization of ready frameworks and reusable components.
  • Code splitting.
  • Code portability.
  • Version control.
  • Exception-handling mechanisms.
  • Use of linter tools, such as SonarQube, ESLint, and more.

Tried and True Techniques We Use to Provide a 360-Degree View of Your Code

Static code analysis

We run a series of automated checks to compare the code against a predefined set of rules or best practices. After that, we manually analyze the findings to exclude false positives.

Manual code review

To gain a deeper insight into the code issues, we examine the source code line by line, taking into account the software architecture and business logic as well as the target of the audit: e.g., assessing code compliance or scalability.

For deeper insights into code security issues, we additionally employ dynamic code analysis. It means we analyze running code and attempt attacks from outside to see how a real-world hacker can find and exploit code vulnerabilities to get hold of an app’s data and functionality.

Where You Win with ScienceSoft

KPI-based approach

We base our audits on code quality KPIs: e.g., Cyclomatic Complexity, Maintainability Index and help you improve project-level KPIs, such as cycle time, deployment frequency, and more.


We precisely target your goals (e.g., confirm or reaffirm compliance, start an evolution project) to offer the best cost-benefit ratio for you.

Actionable advice and practical help

Not limiting ourselves to code evaluation, we are ready to provide clear guidelines on or fully take over code improvement and error remediation.

Driving Code Improvements: Success Stories by ScienceSoft

Code Audit for a Windows Application and an iOS App

Code Audit for a Windows Application and an iOS App

ScienceSoft's team performed a manual code review and automated static code analysis to assess the code's readability, correctness, robustness, efficiency, and logical structure, identify code issues, and comment on the code style. After that, we restored the source code documentation and provided build instructions to facilitate the application's further development.

Cloud Application Code Review and Pentesting for an Award-Winning IT Company

Cloud Application Code Review and Pentesting for an Award-Winning IT Company

ScienceSoft’s security testers performed automated source code review with IBM Application Security on Cloud, while our solution architect conducted a manual source code review. The combination of manual and automated checks allowed the team to get in-depth understanding of the critical source code issues that could compromise the app’s functionality and lead to data leakage.

Comprehensive Quality Assessment of a Patient Portal for a US Healthcare Service Provider

Comprehensive Quality Assessment of a Patient Portal for a US Healthcare Service Provider

As part of the quality assessment of a patient portal, ScienceSoft’s team audited its source code to evaluate its security, testability, consistency, and logical structure. We detected multiple severe errors in the code and provided remediation guidance.

Quality Assessment and Redesign of a Custom EHR Application for a US Chiropractic Care Provider

Quality Assessment and Redesign of a Custom EHR Application for a US Chiropractic Care Provider

ScienceSoft reviewed the application code and verified its compliance with PSR standards. As the code turned out to be ill-structured, overwhelmed with software workarounds, had many redundant lines and contained security vulnerabilities that could lead to PHI disclosure, ScienceSoft’s team recommended redevelopment of the solution and assisted with its redesign.

UX/UI Audit and Code Review of an Android App for Delivery Service Drivers

UX/UI Audit and Code Review of an Android App for Delivery Service Drivers

As a result of application code and architecture audit, ScienceSoft’s senior Android developer revealed multiple issues with deprecated third-party dependencies, memory leaks, and insufficient test coverage. He provided a comprehensive report describing the causes of the issues and the necessary fixes to improve the code and its maintainability.
