Source Code Review

Secure Source Code Review & SAST

Manual, expert-led secure code review combined with SAST tooling across your critical applications: authentication and authorization logic, input handling, crypto usage, secrets management and dependency risk - mapped to OWASP ASVS with developer-ready fixes.

Praxis-Q's Source Code Review combines manual expert analysis with SAST tooling to uncover business-logic flaws, authentication bypasses, and hardcoded secrets that automated scanners miss. Our India-headquartered, globally-delivery team reviews your critical applications against OWASP ASVS standards, identifying vulnerabilities in auth logic, input handling, cryptography, and dependency management. Every finding maps to fix-ready remediation with code examples, supporting PCI DSS 6.x secure-SDLC compliance and ISO 27001 evidence requirements. Language-agnostic across JavaScript, Python, Java, Go, PHP, and mobile platforms—we deliver within 15–20 business days, with re-review included to verify remediation. Unlike penetration testing which examines runtime exposure, code review captures design flaws and secrets at their source, providing developers and auditors with actionable intelligence before production deployment.

Secure Source Code Review & SAST

The Problem

Scanners miss business-logic flaws, and pen tests only see what's exposed at runtime. Vulnerabilities born in code - broken auth logic, injection paths, hardcoded secrets - ship to production unseen.

Why Source Code Review Matters

Automated SAST tools find syntax and known patterns; penetration testing exposes runtime vulnerabilities. But business-logic flaws, broken authorization, hardcoded secrets, and unsafe crypto usage live in the code before deployment. A single weak password reset flow or unvalidated token generation can bypass all perimeter controls. Manual expert code review, paired with tuned SAST scanning, catches these design-level risks that scanners and runtime tests alone cannot. Praxis-Q's developers and security architects read your codebase like an attacker, tracing authentication chains, input validation, and secrets management to surface threats before they reach production.

Our Review Methodology

We begin with scope definition—identifying critical repositories, entry points, and threat models aligned to your business. SAST tooling provides an automated baseline, tuned to your tech stack to minimize noise. Our expert team then manually reviews authentication, session handling, input validation, cryptography usage, and dependency risk, mapping each finding to OWASP ASVS levels. Every vulnerability receives a CVSS score, remediation code snippet, and developer-ready guidance. Final re-review validates fixes and generates auditor-ready evidence for PCI DSS 6.x and ISO 27001 compliance. Turnaround: 15–20 business days, with ongoing CI integration for continuous control.

Coverage Across Languages & Stacks

Whether your applications are built in JavaScript/TypeScript, Python, Java, Go, PHP, or mobile platforms, our language-agnostic approach ensures comprehensive review. We assess authentication and authorization logic, input handling and injection risks, cryptographic implementations, secrets management, and third-party dependency vulnerabilities. Our findings reference OWASP Top 10 and ASVS controls, translating security requirements into code-level fixes. Each finding includes a remediation example in your language, enabling developers to patch immediately. Re-review after fixes is included, ensuring closure evidence and auditor confidence.

Compliance & Audit Evidence

Source code review generates essential evidence for PCI DSS 6.x Secure SDLC compliance, ISO 27001 control implementation, and HIPAA secure development requirements. Our ASVS-mapped findings demonstrate control effectiveness to auditors and regulators. The code-level remediation and re-review process creates a documented trail of secure development practice, reducing audit scope and risk. For organizations undergoing SOC 2, DPDP, or RBI audits, code review findings and remediation closure reports strengthen your security posture and compliance narrative.

Integration into Your Security Program

Code review integrates into your CI/CD pipeline as an ongoing control, not a one-time assessment. Praxis-Q configures SAST tools within your development workflow, enabling early detection of regressions and new vulnerabilities before merge. Combined with VAPT and network penetration testing, source code review closes the gap between design-time and runtime security. Our India-based team supports global deployments, with fast-track turnaround and re-review cycles, ensuring your development velocity remains uncompromised while security governance strengthens.

Frequently Asked Questions

How is this different from a VAPT?

VAPT tests the running application from outside; code review reads the source itself, catching logic flaws, dead admin routes and secrets that never surface at runtime. Together they give full coverage.

Do you need our full repository?

We review the agreed scope only, under NDA, on your infrastructure or a controlled copy - whichever your policy requires.

How does source code review differ from VAPT?

VAPT (Vulnerability Assessment & Penetration Testing) examines the running application from outside, revealing runtime exposures. Source code review reads the source itself, catching business-logic flaws, dead admin routes, hardcoded secrets, and unsafe crypto usage that never surface at runtime. Together, they provide complete coverage: code review finds design risks, VAPT finds deployment risks.

Do you need access to our entire repository?

No. We review the agreed scope only—critical services, APIs, and authentication modules—under strict NDA. Review occurs on your infrastructure, a controlled sandbox, or an isolated copy per your security policy. We never store or distribute source code beyond the engagement period.

What standards do you map findings to?

Every finding maps to OWASP ASVS (Application Security Verification Standard), OWASP Top 10, and CWE references. Findings also align with PCI DSS 6.x, ISO 27001 Secure SDLC, HIPAA secure development, and GDPR data protection requirements, enabling direct compliance evidence for auditors.

How long does a code review typically take?

Praxis-Q delivers standard code reviews within 15–20 business days, depending on scope and codebase size. Our fast-track USP ensures rapid turnaround without compromising depth. Re-review cycles after remediation typically take 5–7 business days, allowing developers to patch and validate quickly.

What languages and frameworks do you support?

We review JavaScript/TypeScript, Python, Java, Go, PHP, and mobile platforms (iOS/Android). Our approach is language-agnostic, with remediation code examples provided in your tech stack, enabling developers to implement fixes without translation overhead.

Can code review integrate into our CI/CD pipeline?

Yes. We configure SAST tools and code review workflows within your CI/CD environment, enabling automated early detection of vulnerabilities during development. This transforms code review from a gate-check into a continuous control, reducing late-stage findings and accelerating secure development velocity.
