Code Review Services

Spotting Imperfections, Driving Improvements

In software development since 1989, ScienceSoft offers all-around code review services to help improve all aspects of code quality: from clarity and maintainability to security and compliance.

Code Review Services
Code Review Services

Code review services involve manual and/or automated examinations of application source code, performed by independent IT professionals able to identify the flaws that can compromise code quality and security. Expert code review helps improve source code performance, clarity, scalability, and maintainability as well as fortify software against cyberattacks.

The Scope of Our Code Review Services

SAST – automated security code review

We reveal:

  • Encryption errors: weak encryption algorithms or strong encryption algorithms with weak implementation (e.g., insecure key storage).
  • Code injection vulnerabilities.
  • XSS (cross-site scripting) vulnerabilities.
  • Buffer overflows: more data is put into the buffer than it can handle.
  • Race conditions: performing two or more operations at the same time.

Manual security-focused code review

We check:

  • Auditing and logging mechanisms.
  • Input/data validation mechanisms.
  • Impersonation/delegation mechanisms.
  • Session management.
  • Communication security.
  • The security of connection strings.
  • Input/output operations security.
  • The presence of serialization filtering.
  • Reflection mechanisms.
  • The presence of obfuscation.
  • If the code is thread-safe.

Additionally, we can:

  • Simulate parameter manipulation, SQL and script injections.
  • Evaluate the security of access to the development infrastructure and codebase.


All-around code review

In addition to SAST and manual review of code security, we check:

  • If descriptive names for code variables are in place.
  • If comments about what particular code functions and methods do are present.
  • If documentation on what the whole code does and what its dependencies are is in place.
  • If the developers can take advantage of ready frameworks and reusable components to get work done faster.
  • If the practice of splitting code into shorter units is observed.
  • If the code is portable.
  • If effective version control is implemented.
  • If linter tools (SonarQube, ESLint) are used.
  • If exception-handling mechanisms are effective.
  • If the required security mechanisms are in place, and more.

Success Stories by ScienceSoft

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 an 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 reviewed its source code to evaluate its security, testability, consistency, and logical structure. They detected multiple severe errors in the code and provided remediation guidance.

Code Audit for a Windows Application and an iOS App

Code Audit for a Windows Application and an iOS App

ScienceSoft's team conducted a detailed 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, they restored the source code documentation and provided build instructions to facilitate the applications' further development.

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.
