Code Security Review

About

DEFION’s Code Security Review is a manual assessment of your application’s source code, designed to uncover vulnerabilities, logic flaws, and insecure implementations that are often missed by penetration testing or automated tools. By directly analyzing the codebase, our experts provide actionable insights that help your development team improve security, quality, and maintainability.

Approach

Our methodology follows four key steps:

1. Scoping – Together we define scope, priorities, and the architectural context of the application.

2. Manual Code Analysis – Security specialists review the source code against secure coding practices and best practices. Each finding is manually validated to eliminate false positives.

3. Reporting – Results are documented in a clear report with risk levels, technical details, and prioritized remediation advice.

4. Knowledge Transfer – Findings can be explained in a follow-up session with your developers to support effective remediation.

Focus Areas

During a Code Security Review we typically examine:

• Logic vulnerabilities and insecure control flows

• Injection flaws (e.g. SQL injection, cross-site scripting)

• Authentication, session handling, and cryptographic implementations

• Insecure use of APIs, cloud or platform-specific functions

• Secrets or hardcoded credentials in code

• Error handling and potential information leakage

• Use of outdated or vulnerable libraries and dependencies

• Maintainability, readability, and secure configuration defaults

Deliverables

At the conclusion of the review you receive:

• Executive Summary – Overview of key findings and risk levels for stakeholders

• Technical Report – Detailed per-issue descriptions, code references, and proof-of-concept examples

• Remediation Guidance – Practical recommendations tailored to your development environment

• Optional Supporting Data – Raw analysis output, screenshots, or logs upon request

All results are delivered securely. DEFION can also provide a third-party statement of findings to support compliance and customer communication if required.

Best Fit For

A Code Security Review is most relevant for:

• Organizations preparing a major release or new platform launch

• SaaS, fintech, eHealth, and IoT product companies

• Development teams seeking external validation of their code

• Software undergoing ISO27001, SOC2, or similar compliance reviews

Why DEFION

Our experts combine development experience with offensive security expertise. Findings are never tool-driven but validated by specialists who apply OWASP Secure Coding Practices, CERT standards, and secure development lifecycle principles. This approach ensures reliable results that directly strengthen your security posture.
