Secure Code Review

Secure Code review is the process of manually reviewing the source code that would highlight issues missed during a black box pentest. This review helps to detect the inconsistencies overlooked during all other security assessments.

Secure code review is a continuous improvement process that an organization goes through to identify and fix potentially risky vulnerabilities in the late stages of the development process. This could be due to poor secure coding practices by the developers responsible for writing the code. As the last threshold before an application moves to production / live environment, secure code reviews are an integral part of the security process. They serve as a sort of final "green tick" to assure you that the code is safe and that all dependencies and controls of the application are secured and functional.

We have a dedicated security assessments FAQ section. Read it here.

Key Benefits



The assessment-execution phase is followed by the analysis & reporting. Defendza performs analysis on the testing output, evaluates the risk impact and likelihood of exploitation in realistic scenarios before providing action plans to remediate the identified risks. All our reports address business as well as the technical audience with supporting raw data, including mitigation measures at strategic and tactical levels. 

Business Logic Analysis

The business logic for the entire application must be reviewed. This is only possible after gaining an understanding of how the application behaves for different privilege levels. From the threat-modelling phase and the knowledge gained, our consultants will be in the position to exploit business logic level vulnerabilities that are often overlooked by the developers

OWASP Top 10 Checks

Our consultants would focus on the top 10 categories of attacks defined by the industry-standard OWASP. This includes:

  • Injection,
  • Broken authentication,
  • Sensitive data exposure,
  • XML External Entities (XXE),
  • Broken access control,
  • Security misconfiguration,
  • Cross-site scripting,
  • Insecure deserialization,
  • Using components with known vulnerabilities and
  • Insufficient logging and monitoring

Review Authentication Architectures

Authentication and authorization problems are prevalent security vulnerabilities. Most mobile apps implement user authentication. Even though part of the authentication and state management logic is performed by the back end service, authentication is such an integral part of most mobile app architectures that understanding its common implementations is important.

"My experience to date with Defendza has been very positive, I look for a flexible, knowledable security "partner" when I engage a PT firm. Pentest means many things to many people and there are many different use cases for both the testing activity and the report generated and I need someone to work with me to get the absolute best value out of my security budget."
