Source Code Review

Source Code Review.

Manual secure code review by OSCP-certified professionals identifying insecure coding patterns, hardcoded secrets, weak cryptography, SQL injection roots, and OWASP ASVS compliance gaps in your application codebase. We review code the way an attacker reads it — looking for exploitable flaws, not just style violations.

  • Manual review — not just automated SAST tool output.
  • OWASP ASVS Level 2 and Level 3 compliance gap analysis.
  • Hardcoded secrets, API keys, credentials and cryptographic weaknesses identified.
  • Framework-specific insecure patterns for Java, Python, Node.js, PHP, Go and more.

What You Will Get

A comprehensive secure code review combining manual expert review with targeted automated analysis. Every finding includes the exact file and line number, a code-level explanation of the vulnerability, the real-world attack scenario, and a code-level fix recommendation specific to your framework and language.

Injection Vulnerability Roots

SQL injection at the ORM and raw query level, SSTI roots, command injection, LDAP injection and XPath injection in your actual codebase.

Authentication & Authorisation

Insecure session management, missing authorisation checks, IDOR in object lookups, broken access control and privilege escalation in code.

Cryptographic Weaknesses

Weak algorithms (MD5, SHA1, DES), insecure key storage, hard-coded encryption keys, insufficient randomness and improper certificate validation.

Hardcoded Secrets

API keys, database credentials, private keys, AWS access keys and other secrets committed to code or configuration files -- including historical git commits.

Third-Party Component Analysis

Dependency audit against known CVEs, outdated libraries with public exploits, and licence compliance review for your entire dependency tree.

CVSS Report & Re-Test

File-and-line referenced findings with code-level fix recommendations. Free re-test after remediation. OWASP ASVS compliance report included.

Our Testing Methodology

  • Codebase Onboarding

    Secure repository access established. Technology stack, framework versions and architecture documented. High-risk areas prioritised for deep review.

  • Manual Expert Review

    Line-by-line review of high-risk modules combined with targeted automated SAST analysis. Every automated finding manually verified before inclusion.

  • CVSS Report in 48h

    File-and-line referenced findings with exact code snippets, attack scenarios and framework-specific fix recommendations for your development team.

  • Re-Test & Certificate

    After your team applies fixes, we re-review the corrected code at no charge and issue a security closure certificate valid for regulatory submissions.

Other VAPT Services We Offer

Web Application VAPT

OWASP Top 10, SQL injection, auth flaws and business logic testing. Every finding manually verified with working proof-of-concept.

Mobile Application VAPT

Android and iOS apps tested with static and dynamic analysis. OWASP MASVS full coverage, cert pinning bypass and insecure storage.

API Security Testing

REST, GraphQL, SOAP and gRPC APIs tested against OWASP API Top 10 2023. BOLA, mass assignment and broken auth.

Cloud Security Assessment

CIS Benchmark assessment for AWS, Azure and GCP -- IAM misconfiguration, public storage exposure and attack path mapping.

Red Team Exercise

Full-scope adversarial simulation mapped to MITRE ATT&CK -- combining cyber exploitation, phishing, vishing and physical intrusion.

Why Manual Code Review Finds What Scanners Miss

Static analysis tools find known vulnerability patterns. They cannot understand business logic, contextual authentication flaws, or the interaction between components across your codebase. Our security engineers manually trace data flows, review authentication logic, and identify insecure design patterns that no automated tool can detect.


Security Engineer Review

Every review conducted by a security engineer -- not a scanner. We read your code the way an attacker would, tracing data flows and logic paths.

Business Logic Coverage

We identify insecure design patterns, authentication bypasses, and authorisation flaws that are only visible through manual code analysis.

OWASP ASVS Compliance

Full assessment against OWASP ASVS Level 2 -- covering authentication, session management, access control, cryptography and more.

Third-Party Dependency Audit

Every dependency in your codebase audited against known CVEs, outdated libraries with public exploits and licence compliance issues -- your supply chain risk made visible.

Hardcoded Secrets Detection

API keys, database credentials, private keys and AWS access keys committed to your repository -- including historical git commits -- identified and reported with remediation steps.

Framework-Specific Patterns

Insecure coding patterns specific to your framework identified -- Spring, Django, Laravel, Express, NestJS -- not generic findings your developers already know about.


The Cost of Insecure Code in Production

Vulnerabilities introduced during development are the cheapest to fix — but the most expensive to ignore. A hardcoded secret found in a code review costs hours to fix. The same secret found after a breach costs Rs 17.9 crore on average, plus DPDPA 2023 penalties of up to Rs 250 crore.

Frequently Asked Questions

What languages and frameworks do you review?

We review code in Java (Spring, Hibernate), Python (Django, Flask, FastAPI), Node.js (Express, NestJS), PHP (Laravel, Symfony), Go, Ruby on Rails, and .NET. For mobile we review Kotlin, Swift, React Native and Flutter. If your stack is not listed, contact us — our team has broad language coverage.

Do you need full access to our repository?

We require read-only access to the relevant repository branches. We never need write access. For organisations with strict IP policies we can also accept a code archive or conduct the review in an air-gapped environment at your premises.

Are your reports accepted by RBI, SEBI and IRDAI?

Yes. Our audit reports are structured to meet the specific submission requirements of the relevant regulatory framework — including the Reserve Bank of India, SEBI, IRDAI, and all other major Indian regulators. We have a 100 percent acceptance record across all regulatory submissions.

How is this different from running SonarQube ourselves?

Automated SAST tools like SonarQube find known patterns but miss business logic flaws, chained vulnerabilities, and context-specific issues. Our manual review finds what scanners miss — the IDOR in your custom authorisation code, the SQL injection hidden in a dynamic query builder, the cryptographic weakness specific to how your app uses a library.

Do you guarantee zero false positives?

Yes. Every finding in our report has been manually verified and proven exploitable with a working proof-of-concept. We never submit raw automated scanner output. If a scanner raises an issue that cannot be confirmed through manual testing it is excluded entirely from the final report.

What happens after we fix the vulnerabilities?

A free re-test is included in every engagement. Once you have remediated the findings, our OSCP-certified testers re-verify every fix to confirm it is effective. We then issue a security closure certificate valid for regulatory and client submissions. The re-test must be used within 60 days of the original report delivery.
