Source Code Reviews

Find security vulnerabilities in your software before you ship it

Undetected vulnerabilities in software are a key source of security issues, so having a third party skilled in secure development is a worthwhile investment. Tangible offers comprehensive manual secure code review services to identify and mitigate potential vulnerabilities in software applications across diverse industries and domains. Our methodology involves a thorough and systematic analysis of your source code, leveraging industry-standard best practices and established secure coding guidelines. Our seasoned experts are skilled in a wide variety of programming languages, from established languages like C to the latest scripting languages.

Seasoned Experts and Proven Methodology

Established through our extensive experience, our secure development team has created a proven methodology that spans information gathering, static code analysis, and an array of manual code review techniques. We identify vulnerabilities and provide a full set of remediation recommendations.

Our methodology follows the approach below, and we then customize for each application, programming language and your individual requirements.

Information Gathering and Preparation

During this initial phase we gather information from relevant stakeholders to gain a deeper understanding of the application’s architecture, programming languages used, and third-party dependencies. We then determine the review strategy and set up a secure review environment.

Static Code Analysis

We complement our manual review with static code analysis, leveraging industry-standard static code analysis tools adept at identifying a wide range of issues, including input validation weaknesses, cross-site scripting (XSS) vulnerabilities, SQL injection flaws, and many other known security vulnerabilities.

Manual Code Review

Our manual code review process is at the core of our methodology, examining security controls, data handling, authentication and authorization, and other critical components. Techniques include including entry point analysis, data flow analysis, security control analysis, configuration analysis, and code quality analysis.

Programing Languages and Tailored Approaches

Our consultants have extensive expertise in reviewing source code written in various programming languages, each with its unique characteristics, potential vulnerabilities, and security considerations. We provide language-specific approaches and considerations, including but not limited to web languages, such as PHP, JavaScript / TypeScript, Java, Python, Ruby, C# / ASP.NET, and Elixir; diverse web platforms like Node.js, Deno, bun, and serverless; mobile languages such as Java, Kotlin, Swift, Objective-C, and React Native; established languages like C/C++, as well as newer languages such as Rust and Golang. We also cover other less popular languages like F#, ColdFusion and Haskell, and video game-oriented languages like Unity’s C# and Godot’s GDScript.

Application Languages

We have extensive experience in reviewing applications written in established programming languages, such as C and C++, Perl, the .NET family (both the .NET framework and the newer dotnet platform), Java, and Python, and are well-versed in identifying language-specific vulnerabilities and security risks. We also stay up to date with emerging programming languages, such as Swift, Ruby, Rust, and Golang and their unique security considerations.

Mobile Languages

Mobile applications have become ubiquitous, but they handle sensitive data and access important device features. When reviewing mobile applications, our focus areas include insecure data storage, improper use of platform APIs, insecure inter-process communication, mobile-specific feature vulnerabilities, sensitive data handling, and root detection.

Web Languages

Web applications are a prime target for attackers due to their widespread use, exposure to the internet, and the sensitive data they often handle. When reviewing web applications, we focus on analyzing input validation and output encoding mechanisms to identify vulnerabilities that could lead to injection flaws, such as cross-site scripting (XSS), SQL injection, and other code injection attacks.
