Secureroot's secure code review services help SaaS, fintech, and enterprise dev teams find security vulnerabilities at the source - combining SAST tooling with manual review by senior application security consultants. Coverage across Java, Python, Node.js, .NET, Go, Ruby, and more. ISO 27001 certified. SOC 2 audit-ready.

















Secure code review is whitebox security testing – certified application security consultants read your application’s source code line-by-line to find security vulnerabilities that black-box testing misses. It combines automated SAST (Static Application Security Testing) tools that scan code for known vulnerability patterns with manual review by senior reviewers who understand how your business logic actually works. The output is a prioritized list of code-level vulnerabilities with exact file locations, vulnerable code snippets, and fix recommendations.
Black-box testing (web app or API pen testing) sees what an attacker sees – and is essential. But many critical vulnerabilities are invisible from outside the application: hardcoded API keys and credentials in source code, weak cryptographic implementations, insecure deserialization, race conditions, and authorization logic flaws buried deep in the codebase. Code review finds these systematically. It’s also the only way to verify your code handles edge cases securely – including the inputs no attacker has thought to try yet but eventually will.
For SOC 2 Type II, ISO 27001, and BFSI compliance, secure code review is increasingly mandatory – auditors want evidence you review code for security, not just test the running app. For development teams shipping new features rapidly, code review catches vulnerabilities before they reach production, when they’re 10-100x cheaper to fix. For high-assurance applications (payment processing, healthcare records, government systems), it’s how you build genuine confidence that critical code paths are secure. Secure code review is foundational to mature application security programs.


We follow OWASP Code Review Guide, OWASP ASVS, and language-specific secure coding standards (Oracle JSS, PEP-8 security, OWASP .NET, Node.js security best practices). Every code review runs through these six steps.

We map your codebase: languages, frameworks, dependencies, architectural patterns, and security-critical modules (auth, payment, data access). We agree scope: full review or focused on specific modules.

We identify the highest-risk areas: authentication flows, authorization checks, data access layers, third-party integrations, and any place that handles user input or sensitive data.

Industry SAST tools (SonarQube, Checkmarx, Semgrep, CodeQL, Snyk Code) scan the entire codebase for known vulnerability patterns – providing baseline coverage and reducing manual workload.

Senior consultants manually review high-risk modules – finding business logic flaws, authorization issues, cryptographic weaknesses, and complex vulnerabilities that no automated tool can catch.

Every finding documented with exact file path, line number, vulnerable code snippet, attack scenario, CVSS scoring, business impact, and code-level fix recommendation with example secure code.

Once your team patches the findings, we verify the fixes at no extra cost. Engagement only closes when everything’s actually fixed.

We scan and manually review the entire codebase for hardcoded secrets: API keys, database passwords, encryption keys, OAuth secrets, AWS access keys, GitHub tokens, SSH keys, and credentials in configuration files. We also audit git history for accidentally committed secrets. Findings include exposed credentials, recommendations for secrets management (AWS Secrets Manager, HashiCorp Vault, Azure Key Vault), and process improvements (pre-commit hooks, secret scanning in CI/CD).
We trace user input from entry points through the codebase to query construction — identifying SQL injection where user input is concatenated into queries instead of parameterized, NoSQL injection in MongoDB/Cassandra queries, command injection where input flows to system() / exec() / Runtime.exec(), LDAP injection in directory queries, and template injection (SSTI). Findings include exact vulnerable lines and prepared statement / safe API replacements.
We audit cryptographic code: weak algorithms (MD5, SHA1, DES, RC4 for non-checksum use), hardcoded encryption keys, weak random number generation (Math.random() for security), improper IV handling (reused IVs in CBC mode, missing IVs), ECB mode misuse, homegrown crypto, weak password hashing (storing as MD5/SHA1 instead of bcrypt/Argon2), and incorrect TLS configurations. We provide language-specific secure implementation examples.
We audit authentication and authorization code paths: missing authorization checks, broken role-based access control, JWT validation flaws (algorithm confusion attacks, missing signature verification), session management issues (predictable session IDs, missing rotation on privilege change), authentication bypass through HTTP verb tampering, and authorization decisions that trust client-controlled data. These are among the highest-impact findings in any code review.
We test deserialization code in Java (Spring, Apache Commons, ObjectInputStream), Python (pickle, yaml.load), .NET (BinaryFormatter, NetDataContractSerializer), PHP (unserialize), Ruby (Marshal.load), and Node.js (node-serialize). Insecure deserialization can lead to remote code execution and has caused major breaches (Equifax, Apache Struts). We identify vulnerable deserialization patterns and recommend safe alternatives.
We identify time-of-check vs time-of-use (TOCTOU) vulnerabilities, race conditions in payment flows where the same transaction can be processed twice, concurrent modification issues in shared state, thread-safety problems in singleton patterns, and atomic operation gaps. Race conditions are notoriously hard to find through black-box testing - code review is the most reliable detection method.
We trace input validation across all entry points: API endpoints, file uploads, message queue consumers, webhook handlers. We identify missing validation, weak validation (regex bypasses, length checks only), validation in wrong layer, and output encoding gaps that lead to XSS in web responses or injection in downstream systems. We map findings to OWASP Top 10 and provide framework-specific validation recommendations.
We audit third-party libraries and dependencies for known CVEs using SCA tools (Snyk, Dependabot, npm audit, OWASP Dependency-Check). We identify outdated packages, vulnerable transitive dependencies, abandoned libraries, and licensing risks. We also review how third-party code is used - many vulnerabilities only matter based on usage context. Output includes update prioritization, version recommendations, and compensating controls where updates aren't immediately possible.

Secure code review is whitebox application security testing where certified consultants read your source code line-by-line to find security vulnerabilities. It combines automated SAST (Static Application Security Testing) tools that scan code for known vulnerability patterns with manual review by senior reviewers who understand your application's business logic. Coverage includes injection vulnerabilities, hardcoded secrets, weak cryptography, insecure deserialization, authorization flaws, and race conditions. The output is a prioritized list of code-level findings with exact file locations and fix recommendations.
Secure code review in India typically costs between ₹80,000 and ₹15,00,000 depending on codebase size, language complexity, and depth. A small microservice (under 10,000 lines) starts around ₹80,000-2,00,000. Mid-size applications (50,000-100,000 lines) run ₹2,50,000-6,00,000. Large enterprise codebases (250,000+ lines) reach ₹6,00,000-15,00,000. Pricing depends primarily on lines of code reviewed manually, not just tool execution. Secureroot provides transparent fixed-price quoting after a free 30-minute scoping call where we review your repository.
SAST (Static Application Security Testing) tools - SonarQube, Checkmarx, Semgrep, CodeQL, Snyk Code — automatically scan source code for known vulnerability patterns. They're fast and find ~50-70% of issues. Manual code review by senior consultants finds the remaining 30-50% — business logic flaws, complex authorization issues, race conditions, and vulnerabilities that require human reasoning to identify. SAST tools also have false positive rates of 20-40% - manual review filters those out. The combination is essential for audit-grade code review; tools alone aren't enough.
Most secure code review engagements complete in 2-6 weeks. A small microservice (under 10,000 lines) takes 1-2 weeks. Mid-size applications (50,000-100,000 lines) run 3-4 weeks. Large enterprise codebases (250,000+ lines) take 5-8 weeks. Adding multiple languages or frameworks extends the timeline. Free retest after remediation typically adds 5-7 business days per remediation cycle. We provide clear timeline commitments in every engagement scope document based on initial codebase assessment.
We support all major languages and frameworks: Java (Spring, Struts, JSP), Python (Django, Flask, FastAPI), JavaScript / Node.js (Express, NestJS, Next.js, Vue, React, Angular), .NET (ASP.NET Core, MVC, WebForms, WCF), Go (Gin, Echo), Ruby (Rails, Sinatra), PHP (Laravel, Symfony, WordPress), Rust (Actix, Rocket), Swift / Objective-C (iOS), Kotlin / Java (Android), and cross-platform mobile (React Native, Flutter, Xamarin). For uncommon languages, we evaluate fit during scoping.
We use industry-standard secure code sharing: (1) Read-only access to your private GitHub / GitLab / Bitbucket repository granted to specific Secureroot consultants under NDA. We can use temporary access expiring after the engagement. (2) Encrypted archive shared via secure file transfer (SFTP, encrypted cloud storage). (3) Self-hosted access - we connect to your environment via VPN and review code on your infrastructure. We sign mutual NDAs before any code transfer. All shared code is deleted from our systems after engagement completion (subject to legal retention requirements).
Our methodology is designed for development team velocity, not against it. We can scope reviews to fit specific release milestones: review only changed/new code (delta review), prioritize critical modules first, or run continuous review parallel to development. We deliver findings incrementally - your team can start fixing issues as we find them, rather than waiting for the final report. For agile teams, we offer sprint-aligned reviews. For pre-release audits (SOC 2 / ISO 27001 prep), we offer fast-track scoping.
Three ways to start: (1) Book a free 30-minute code review scoping call - our senior consultants review your codebase metadata (size, languages, frameworks), identify priority modules, and recommend the right engagement scope. No obligation. (2) Email info@secureroot.co with codebase details (languages, frameworks, lines of code, compliance requirements, timeline) and we'll respond within one business day. (3) Call +91 73071 48874 during business hours. For SOC 2 / ISO 27001 audit windows, we accommodate fast-track scoping.
