Source Code Security Review

Source Code Security Review

A Source Code Security Review is a manual assessment and examination of application code to identify vulnerabilities and insecure design practises

What you'll get:
  • A comprehensive analysis of your application's source code, architecture, and design
  • Customized solution that addresses your application's unique security needs
  • A comprehensive report with detailed findings and remediations steps
  • Patch validation to confirm vulnerability remediation

What is a Source Code Security Review?

A source code security review is a manual examination of your application's source code by experienced security consultants to identify vulnerabilities, insecure design patterns, and security weaknesses that cannot be found through external testing alone. By analyzing the code directly, our reviewers can trace data flows, identify dangerous function calls, evaluate authentication and authorization logic, and uncover vulnerabilities that would be extremely difficult to detect from a black-box perspective.

Unlike automated static analysis tools that produce high volumes of false positives, a manual source code review leverages human expertise to understand your application's business logic, identify complex vulnerability chains, and provide context-aware remediation guidance. Our reviewers focus on the security-critical areas of your codebase — authentication, authorization, input handling, cryptography, and data access layers.

DarkPoint Security's source code security reviews combine manual expert analysis with targeted automated scanning to provide comprehensive coverage of your application's source code, identifying both common vulnerabilities and subtle security flaws in your application's design and implementation.

Why Your Organization Needs a Source Code Security Review

Source code review provides the deepest level of security insight into your application. It finds vulnerabilities that no amount of external testing can detect.

  • Find Hidden Vulnerabilities — Identify security flaws in authentication logic, access control implementations, and data handling that are invisible to black-box testing
  • Shift Security Left — Catch vulnerabilities during development rather than after deployment, reducing remediation costs by orders of magnitude
  • Compliance Requirements — Meet PCI DSS, SOC 2, and other frameworks that recommend or require secure code review as part of a comprehensive security program
  • Improve Development Practices — Our findings and remediation guidance help your development team adopt secure coding practices that prevent future vulnerabilities

Our Code Review Methodology

DarkPoint Security follows a structured approach to source code review:

  • OWASP Code Review Guide — Our primary framework for identifying security vulnerabilities at the code level
  • OWASP Application Security Verification Standard (ASVS) — Defines the security requirements we verify across your application's code
  • CWE (Common Weakness Enumeration) — Provides standardized classification for the vulnerabilities we identify
  • Language-Specific Security Standards — We apply security best practices specific to your programming language and framework

Our review process begins with architecture analysis to understand your application's design and identify high-risk areas. We then perform manual code review focusing on security-critical functions, supplemented by targeted automated scanning to ensure broad coverage. Each finding is validated and contextualized with severity ratings and specific remediation guidance for your codebase.

What We Review

Our source code security reviews cover a comprehensive range of vulnerability categories:

  • Injection vulnerabilities (SQL, NoSQL, command, LDAP)
  • Authentication and session management logic
  • Authorization and access control implementation
  • Cryptographic implementation and key management
  • Input validation and output encoding
  • Error handling and information disclosure
  • Secure communication (TLS configuration)
  • File handling and path traversal
  • Hardcoded secrets, API keys, and credentials
  • Insecure deserialization
  • Race conditions and concurrency issues
  • Memory safety issues (buffer overflows, use-after-free)
  • Third-party library and dependency vulnerabilities
  • Business logic flaws
  • Logging and audit trail implementation
  • Configuration and deployment security

Frequently Asked Questions

We perform security reviews across all major programming languages including Python, Java, C#/.NET, JavaScript, TypeScript, Go, Ruby, PHP, C, C++, Swift, Kotlin, and Rust. Our team has experience with all common web frameworks, mobile frameworks, and backend architectures. We tailor our review approach to the specific language and framework security considerations.

Automated static analysis tools can find common patterns like SQL injection or XSS, but they produce many false positives and cannot understand business logic, complex data flows, or architectural security issues. A manual code review by an experienced security consultant identifies subtle vulnerabilities like authorization logic flaws, race conditions, and insecure design patterns that automated tools cannot detect. We use automated tools to supplement our manual review, combining both for maximum coverage.

We take the confidentiality of your source code extremely seriously. All code is accessed through secure channels (encrypted repositories or secure file transfer), reviewed only by authorized security consultants, and stored on encrypted systems. We sign NDAs before every engagement. As a Canadian-based firm, your code and all review data remain within Canadian jurisdiction. After the engagement, we securely delete all copies of your source code.

The duration depends on the size and complexity of your codebase. A focused review of critical security components (authentication, authorization, payment processing) for a medium-sized application typically takes 1 to 2 weeks. A comprehensive review of a larger codebase may take 2 to 4 weeks. We can also scope the review to focus on recent changes or specific high-risk areas for faster turnaround.
