Code Reviewfor Security
Manual and automated source code review to identify vulnerabilities, authentication flaws, data exposure risks and business logic issues.
Review Coverage
A review focused on real vulnerabilities
The goal of the review is to identify exploitable risks in the source code before they reach production.
Expert Review
Analysis focused on security and real-world vulnerabilities.
Manual + SAST
A combination of automated analysis and manual validation.
Multiple Technologies
Coverage across a range of modern stacks.
Technical Reports
Clear evidence and actionable remediation guidance.
Most common risks found in source code
Critical vulnerabilities frequently arise in authentication, authorization, input handling and business logic.
SQL Injection
Unsafe queries, parameter concatenation and missing prepared statements.
Hardcoded Secrets
Credentials, tokens and sensitive keys exposed in code or repositories.
Broken Access Control
Authorization flaws that allow unauthorized access to features and data.
Insecure Cryptography
Misuse of cryptographic algorithms, weak keys or insecure implementations.
Dependency Risks
Vulnerable libraries, outdated dependencies and insecure components.
Business Logic Flaws
Flaws in application flow and exploitable business rules.
Review methodology
The review combines automated tooling with expert manual validation to identify real risks.

Why Does Your Code Need a Security Review?
Source code vulnerabilities are the root cause of 70% of application security failures. A security code review identifies critical bugs, backdoors, hardcoded credentials and logic flaws before the code reaches production. It is the cheapest and most effective moment to fix vulnerabilities: 100x cheaper than fixing them in production.
Key risks of not running a pentest:
Vulnerabilities in production
SQL injection, XSS and other exploitable flaws
Exposed credentials
API keys, passwords and secrets hardcoded in the source
Vulnerable libraries
Dependencies with known CVEs that go unnoticed
Security technical debt
Code smells and anti-patterns that turn into critical flaws
Our code review combines automated static analysis (SAST) with expert manual review to find vulnerabilities that scanners miss.
How Does Our Code Review Work?
A hybrid methodology: automated tooling + expert manual analysis:
Automated Static Analysis (SAST)
1-2 daysA full scan of the code with specialized tooling:
- Source code analysis across all major languages
- Identification of OWASP Top 10 vulnerabilities
- Detection of hardcoded secrets (API keys, passwords)
- Dependency analysis (SCA - Software Composition Analysis)
- Verification of compliance with secure coding standards
Tools: SonarQube, Semgrep, Snyk, Checkmarx, GitGuardian
Expert Manual Review
3-5 daysHuman analysis of business logic and context:
- Business logic flaws (validation bypasses)
- Race conditions and concurrency issues
- Authorization and access control flaws
- Analysis of sensitive data flows
- Security code smells and anti-patterns
Tools: Review by certified senior specialists (OSCP, GWAPT)
Validation and Prioritization
1-2 daysConfirming vulnerabilities and analyzing their impact:
- Elimination of false positives
- Severity classification (CVSS 3.1)
- Analysis of real-world exploitability
- Prioritization by business risk
- PoC (proof of concept) for critical findings
Tools: Validation in a test environment whenever possible
Report and Remediation
1-2 daysActionable documentation for developers:
- Technical report with the vulnerable code snippets
- Specific remediation recommendations
- Secure code examples (before/after)
- Integration with issue trackers (Jira, GitHub Issues)
- Presentation meeting and Q&A with the dev team
Tools: 30 days of follow-up support for questions
Investment: How Is a Code Review Priced?
The investment depends on the size and complexity of the codebase:
| Size | Typical Scope | Estimated Timeline |
|---|---|---|
| Small Project | Up to 10k lines of code | 3-5 days |
| Medium Project | 10k-50k lines of code | 5-10 days |
| Large Project | 50k-200k lines of code | 10-20 days |
| Enterprise/Monolith | 200k+ lines of code | 20-40 days |
Factors That Influence Pricing:
- Number of lines of code (LOC)
- Number of languages and frameworks
- Code complexity (microservices, monolith)
- Whether infrastructure as code (IaC) review is needed
- Urgency and desired SLA

Frequently Asked Questions
Answers to the most common questions about our pentest services
1What is the difference between a code review and a pentest?
A code review analyzes the source code (white-box) to find vulnerabilities before deployment. A pentest tests the running application (black/gray-box) the way an external attacker would. Ideally, do both: code review during development and a pentest before releases.
2Which languages do you review?
JavaScript/TypeScript, Python, Java, C#/.NET, PHP, Ruby, Go, C/C++, Swift, Kotlin and others. We have specialists in modern frameworks (React, Angular, Vue, Spring, Django, Laravel, etc.).
3Do I need to give you access to the repository?
Yes, but we sign an NDA first. Access can be through a repository clone, a zip export or temporary read-only access to GitHub/GitLab/Bitbucket. All data is deleted once the project ends.
4Do you analyze dependencies and libraries as well?
Yes! We perform SCA (Software Composition Analysis) to identify libraries with known CVEs and problematic licenses, and we recommend safe upgrades.
5How long does it take?
From 3-5 days (small projects) to 20-40 days (large enterprise monoliths). The timeline depends mainly on the size of the codebase (LOC) and its complexity.
6Do you integrate with our CI/CD?
Yes! We can set up automated SAST analysis in your pipeline (GitHub Actions, GitLab CI, Jenkins, CircleCI). Ideal for continuous reviews on every commit/PR.
7Do you fix the code as well?
We provide detailed recommendations and examples of corrected code. If you prefer, we also offer pair programming with your team as an add-on service to implement critical fixes.
8How do I request a quote?
Send us the repository (if possible) or your project statistics (LOC, languages, stack). We run a free preliminary analysis and come back with a proposal within 48 hours.
