Security Code Review. Find Vulnerabilities Before Attackers Do.
Expert manual code review combined with automated security testing (SAST/DAST) to identify vulnerabilities in your applications. We analyze your source code line by line to uncover security flaws that scanners miss.
Application Security
Software vulnerabilities are the leading cause of data breaches. Secure code is not optional—it's essential.
Security Challenges Development Teams Face
Modern development moves fast, but security often struggles to keep pace. From AI-generated code to complex supply chains—these challenges put your applications and data at risk.
AI & Vibe Coding Risks
GitHub Copilot, ChatGPT, and "vibe coding" accelerate development but introduce code no human fully reviewed. AI-generated code often contains hidden vulnerabilities, insecure patterns, and hallucinated APIs.
Developer Security Gap
Developers are experts in building features, not security. The 100:1 developer-to-security ratio means vulnerabilities slip through every sprint.
Supply Chain Complexity
Modern applications rely on hundreds of third-party libraries and dependencies. One compromised package can expose your entire stack—as Log4Shell and SolarWinds proved.
Speed vs. Security Trade-offs
Pressure to ship fast means security reviews get skipped or rushed. Each release accumulates technical debt that eventually becomes a breach.
Scanner Blind Spots
Automated SAST/DAST tools generate false positives and miss business logic flaws, authentication bypasses, and race conditions. Without expert analysis, critical issues go undetected.
Legacy Code Burden
Inherited codebases contain years of accumulated vulnerabilities. No one remembers why security decisions were made—or weren't made.
Compliance Mandates
PCI-DSS, SOC 2, ISO 27001, HIPAA, and GDPR all require demonstrable secure development practices. Auditors demand evidence of code security.
Outsourced Development
Third-party developers and agencies build code without visibility into your security standards. Trust but verify—external code needs independent review.
Frequent Technology Changes
New frameworks, languages, and paradigms emerge constantly. Security teams struggle to keep expertise current across an ever-expanding landscape.
8 Ways Code Review Makes
Security code review transforms application security from a cost center to a competitive advantage.
Detect Vulnerabilities Early
Find and fix security issues during development, not after attackers exploit them in production.
Catch OWASP Top 10, injection flaws, and logic bugs before they reach production
Reduce breach risk and avoid costly incident response
Reduce Remediation Costs
Fixing vulnerabilities in development is 6x cheaper than fixing them in production, and 100x cheaper than post-breach.
Fix issues when context is fresh and code is still being worked on
Lower total cost of ownership for application security
Increase Code Visibility
Gain deep understanding of how your applications work from a security perspective.
Understand security implications of architectural decisions
Make informed decisions about technical investments
Build Security into SDLC
Regular reviews embed security best practices into your development culture.
Learn from expert feedback and improve secure coding skills
Demonstrate due diligence and mature security practices
Validate Third-Party Code
Ensure outsourced development and open-source components meet your security standards.
Verify vendor code quality and dependency security
Reduce supply chain risk and vendor liability
Support Compliance
Provide evidence of secure development practices for auditors and certification bodies.
Generate documentation required for PCI-DSS, SOC 2, ISO 27001
Satisfy regulatory requirements and customer security questionnaires
Comprehensive Testing Categories
We combine multiple testing methodologies to provide comprehensive coverage of your application security posture.
Expert Human Analysis
Our security engineers manually review your source code line-by-line, identifying vulnerabilities that automated tools miss. We analyze business logic, authentication flows, authorization controls, and data handling.
Learn MoreHow our code review engagement works
A structured approach combining automated scanning with expert manual analysis for comprehensive coverage.
Scoping & Planning
We understand your application architecture, technology stack, and security concerns. Together we define scope, access requirements, and timeline.
Automated Analysis
We run enterprise-grade SAST tools across your codebase to identify common vulnerability patterns and create a baseline for manual analysis.
Manual Code Review
Our security engineers dive deep into your code, focusing on high-risk areas, authentication flows, data handling, and business logic.
Dynamic Testing
We complement static analysis with runtime testing, verifying vulnerabilities are exploitable and identifying issues only visible during execution.
Analysis & Reporting
We analyze all findings, eliminate false positives, prioritize by risk, and create comprehensive documentation with remediation guidance.
Delivery & Support
We present findings to your team, answer questions, and provide ongoing support during remediation including free retesting.
