What We Review in Your Code

Comprehensive source code security review covering injection, authentication, cryptography, and supply chain dependencies.

SQL and NoSQL Injection

Identify unsanitised database queries, ORM bypass, and query construction patterns that allow injection attacks across SQL and NoSQL databases.

Command and Code Injection

Detect operating system command injection, server-side code injection, and template injection vulnerabilities in backend code.

Business Logic Flaws

Review application logic for bypass opportunities, race conditions, and state manipulation that automated tools cannot detect.

XSS and Output Encoding

Identify cross-site scripting vulnerabilities including reflected, stored, and DOM-based variants with encoding and sanitisation gaps.

Path Traversal and File Inclusion

Detect file path manipulation, directory traversal, and local/remote file inclusion vulnerabilities in file handling code.

Deserialization and Type Juggling

Identify insecure deserialization, type confusion, and object injection vulnerabilities that can lead to remote code execution.

Authentication and Session

Review authentication mechanisms, session management, token handling, and multi-factor implementation for bypass vulnerabilities.

Access Control

Identify broken access control, privilege escalation paths, and IDOR vulnerabilities in authorisation and permission enforcement code.

Cryptographic Weaknesses

Detect weak encryption algorithms, hardcoded keys, insecure random number generation, and improper certificate validation.

Password and Secret Storage

Review password hashing implementations, secret management patterns, and credential storage for weakness and exposure.

OAuth and SSO Integration

Assess OAuth 2.0, OpenID Connect, and SAML implementations for token manipulation, redirect abuse, and configuration weaknesses.

API Key and Credential Handling

Detect hardcoded API keys, credentials in source code and configuration files, and insecure credential transmission patterns.

Dependency and Supply Chain

Audit third-party libraries and packages for known vulnerabilities, outdated versions, and compromised dependency risks.

Container and Infrastructure as Code

Review Dockerfiles, Kubernetes manifests, and IaC templates for security misconfigurations and privilege escalation paths.

Configuration and Secrets

Identify insecure default configurations, debug modes enabled in production, and secrets hardcoded in source code or config files.

Server and Framework Hardening

Assess web server configurations, framework security settings, and CORS policies for misconfigurations and exposure.

Input Validation and Encoding

Review input validation patterns, content type handling, and encoding practices for bypass opportunities and type confusion.

Data Storage and Logging

Assess data storage patterns, encryption at rest, logging of sensitive data, and compliance with data protection requirements.

Methodology

How We Run a Secure Code Review

A structured six-phase process combining SAST automation with manual expert review, from scoping through verified remediation.

Phase 01

Scoping and Threat Modelling

Define the codebase scope, critical components, and threat model aligned with OWASP and CWE to prioritise review effort.

Phase 02

SAST and Dependency Scan

Automated static analysis using industry-leading SAST tools and dependency vulnerability scanning to identify known vulnerability patterns.

Phase 03

Manual Expert Review

Line-by-line manual code review by security engineers to find logic flaws, business logic bypasses, and context-specific vulnerabilities that tools miss.

Phase 04

Authentication and Crypto Deep-Dive

Focused review of authentication flows, session management, cryptographic implementations, and access control enforcement code.

Phase 05

Reporting and Fix Snippets

CVSS-scored findings report with OWASP and CWE mapping, proof-of-concept code, and fix code snippets for every vulnerability.

Phase 06

Re-Test and Verification

Free re-test after your team applies fixes to confirm all identified vulnerabilities have been effectively resolved.

Who It's For

Built for Organisations That Ship Code

Development-Heavy Startups

Startups shipping code rapidly that need to validate security before releases without slowing down development velocity.

Enterprises with Custom Software

Organisations with custom-built applications where source code is available and security gaps need to be found before deployment.

Regulated Industries

Financial services, healthcare, and government with compliance requirements for secure code review under PCI-DSS, HIPAA, and ISO 27001.

FAQ

Questions We Get Asked Often

Secure code review is a systematic examination of source code to identify security vulnerabilities before deployment. It combines automated SAST analysis with manual expert review to find injection flaws, authentication bypasses, cryptographic weaknesses, and logic errors that automated tools miss.

Scyverge reviews code in all major programming languages including Python, Java, JavaScript, TypeScript, Go, Rust, C/C++, C#, PHP, Ruby, and Swift. Our engineers are language-agnostic and focus on security patterns regardless of technology stack.

Code review analyses source code directly to identify vulnerabilities at the code level, while penetration testing tests running applications from an attacker's perspective. Code review finds more vulnerabilities, catches issues earlier in development, and provides fix code snippets. Penetration testing validates runtime behaviour.

Yes. Every finding includes a fix code snippet showing exactly how to remediate the vulnerability. We also provide the vulnerable code context, the CWE classification, and the recommended fix pattern for your specific framework and language.

Typical engagements take 5 to 15 business days depending on codebase size, language complexity, and scope. We provide a precise timeline after reviewing the repository structure and defining the review scope.
