Cybersecurity Consulting Firm – Cyber Castellum
Software applications are ubiquitous, and all software have vulnerabilities. Identifying and addressing security issues in software is difficult, however addressing them at the source is optimal and reduces the cost of maintaining the software and need for large investment in patch-on technologies.
Our secure source code review service goes beyond automated scanning tools by combining deep manual analysis with targeted static techniques. We examine your application’s source code line by line to uncover vulnerabilities that are often missed in dynamic testing and black-box assessments. From insecure authentication logic to hidden backdoors and third-party library flaws our certified experts identify the real risks early, enabling you to fix issues at the root and strengthen your application before deployment.
We treat code review as a critical part of your application’s security lifecycle. Every line matters when protecting your data, users, and reputation. Our source code assessments are designed to be precise, language-aware, and business-driven.
We read your code like an attacker would spotting logic flaws, trust boundaries, and vulnerable flows beyond tool-based detection.
We use vetted static analysis tools (e.g., SonarQube, Semgrep) to highlight common coding vulnerabilities, configuration issues, and quality gaps.
We check your codebase for insecure or outdated third-party packages that increase your exposure.
Our review includes detailed inspection of auth logic, privilege escalation risks, and session handling implementation.
We highlight secure coding principles, best practices violations, and provide development feedback to improve team maturity.
Every issue is backed by file names, line numbers, proof-of-risk, and remediation steps ready for your dev team to act on.
