What is Source Code Review?
Source Code Review involves a thorough analysis of your application's codebase to detect potential security vulnerabilities, bugs, and inefficiencies. Our expert security analysts examine your code line by line to identify weaknesses that could be exploited by attackers.
This proactive approach helps organizations identify security issues early in the development lifecycle, reducing the cost and effort required to fix vulnerabilities later and ensuring secure coding practices throughout your development process.
Key Benefits of Source Code Review
Our source code review services provide comprehensive security benefits to protect your applications and development processes.
Automated and Manual Code Analysis
Make your APIs against cyber threats. By finding weak spots and gaps, we help you fix them before hackers can use them.
Vulnerability Identification
We uncover both common and advanced security vulnerabilities, ensuring that nothing goes unnoticed.
Risk Mitigation
We provide actionable recommendations to mitigate identified risks and improve your security posture.
Compliance Assistance
Our team helps you meet security standards and regulatory requirements through comprehensive code analysis.
Custom Reports
You will receive detailed reports highlighting issues and suggestions for improving code security.
Continuous Monitoring and Support
We offer ongoing support to monitor your code security over time and address emerging threats.
Types of Code Review We Perform
We perform comprehensive code reviews across multiple dimensions to ensure complete security coverage.
Static Analysis
Automated analysis of source code without executing the program to identify security vulnerabilities, coding errors, and compliance issues.
Dynamic Analysis
Testing the application while it's running to identify runtime vulnerabilities and security weaknesses in real-world scenarios.
Manual Code Review
Expert security analysts manually review code to identify complex vulnerabilities that automated tools might miss.
Architecture Review
Analysis of application architecture and design patterns to identify security flaws at the structural level.
Common Code Vulnerabilities We Find
Our code review process identifies a wide range of security vulnerabilities that could compromise your application.
SQL Injection
Identify SQL injection vulnerabilities that could allow attackers to access, modify, or delete database data.
Cross-Site Scripting
Detect XSS vulnerabilities that could allow attackers to inject malicious scripts into web pages viewed by users.
Authentication Flaws
Identify weak authentication mechanisms that could allow unauthorized access to sensitive resources.
Input Validation
Find insufficient input validation that could lead to buffer overflows, injection attacks, and other exploits.
Cryptographic Issues
Identify weak encryption, improper key management, and other cryptographic vulnerabilities.
Configuration Errors
Detect insecure configurations, default credentials, and other setup-related security issues.
Our Review Process
Our systematic source code review process ensures comprehensive security assessment of your codebase.
1. Code Collection
We collect the complete codebase, including dependencies and configuration files for comprehensive analysis.
2. Automated Scanning
Utilize advanced static analysis tools to identify common vulnerabilities and coding issues.
3. Manual Analysis
Expert security analysts perform in-depth manual review to identify complex vulnerabilities and logic flaws.
4. Risk Assessment
Evaluate identified vulnerabilities based on severity, exploitability, and potential business impact.
5. Reporting
Provide comprehensive reports with detailed findings, remediation guidance, and security recommendations.
6. Follow-up Support
Offer ongoing support to help your team implement security fixes and improve secure coding practices.
Frequently Asked Questions
Everything you need to know about source code security review.
SAST (Static Application Security Testing) uses automated tools like Semgrep or SonarQube to scan code against known vulnerability patterns — fast and broad, but with false positive rates of 30–40% and zero ability to understand business logic. Manual code review involves a security analyst reading the code as a developer and thinking like an attacker — identifying logic flaws, insecure design decisions, and multi-step vulnerabilities no tool can detect. iSecNet performs both: SAST for breadth, manual review for depth and zero false positives in the final report.
You can share your full codebase or specific modules — iSecNet works either way. A full codebase review gives the most comprehensive coverage and finds vulnerabilities in shared libraries, authentication modules, and data handling layers. A targeted review of specific modules (payment processing, authentication, API layer) is faster and more cost-effective when you have a defined high-risk area. All code is shared under a signed NDA before access, stored securely, and deleted after the engagement is complete.
Hardcoded secrets are API keys, database passwords, JWT signing keys, AWS credentials, or other sensitive values embedded directly in source code instead of environment variables or a secrets manager. Anyone who accesses the code — a new employee, a contractor, or an attacker who finds your repository on GitHub — immediately has production credentials. iSecNet scans every file for hardcoded secrets using pattern matching and entropy analysis, and checks your git history for secrets that were committed and later deleted but remain in version control.
iSecNet checks for: use of broken algorithms (MD5, SHA-1 for passwords, DES/3DES for encryption), hardcoded encryption keys or IVs, predictable random number generation using Math.random() in security contexts, improper JWT signing (using 'none' algorithm or weak secrets), insecure password hashing (storing passwords as plain MD5 instead of bcrypt/Argon2), and TLS certificate validation disabled in HTTP client code — a common shortcut developers use during testing that gets shipped to production.
iSecNet delivers a Technical Report with every finding mapped to the exact file name and line number, the vulnerability category, a code snippet showing the insecure pattern, a risk rating (Critical/High/Medium/Low), and a specific fix recommendation with a secure code example. You also receive an Executive Summary for non-technical stakeholders. The report is delivered within 7–10 working days, and iSecNet includes a free re-review of remediated findings.
Yes. ISO 27001 Annex A Control 8.28 (Secure Coding) explicitly requires organisations to apply secure coding principles and review code for vulnerabilities. SOC 2 Trust Service Criteria CC8.1 requires security review of code changes. PCI-DSS Requirement 6.3 mandates vulnerability identification in custom code before release. iSecNet's code review report maps findings to each relevant control, giving you documented evidence of compliance for auditors.
