Offensive Security & VAPT
Secure Code Review
Find vulnerabilities before they ship. We combine static analysis with expert manual review of your most security-sensitive code - auth, crypto, input handling, access control - and pair findings with secure-coding guidance.
Typical timeline
8–12 business days
Engagement model
Grey / black / white box
How it runs
Kickoff → test → report → re-test
Overview
Remediating security vulnerabilities after deployment is incredibly expensive. A secure code review identifies security flaws early in the software development lifecycle (SDLC), analyzing the application's source code for logical flaws, cryptographic errors, and insecure coding patterns.
We combine high-fidelity Static Application Security Testing (SAST) tools with extensive manual review by senior security engineers. We focus our manual efforts on high-risk logical components - such as authentication modules, authorization checks, payment flows, and cryptographic implementations - to deliver actionable remediation guides.
At a glance
- Manual review of auth, crypto, access control and input handling

- Secure-coding guidance for your team
- Findings mapped to CWE and OWASP
Coverage
What we cover
Authentication Logic
Verifying secure password hashing, token generation, MFA checks, and session management code.
Authorization Checks
Ensuring rigorous access control checks are enforced on every backend controller and API resolver.
Data Sanitization
Reviewing input validation and output encoding patterns to prevent SQLi, XSS, and command injections.
Cryptographic Practices
Scanning for hardcoded secrets, weak encryption algorithms, and insecure key storage.
Business Logic Flows
Manually tracing complex multi-step processes like shopping carts and password resets for bypass routes.
Dependency Hygiene
Analyzing third-party libraries and packages for known vulnerable components and license compliance.

Why A5
Why teams pick us
Manual-first, not scan-first
Senior testers hand-craft test cases for your business logic - scanners only set the baseline.
Proof, not guesses
Every finding ships with a working proof-of-concept and exact reproduction steps.
Fix-focused reporting
Remediation with code and config examples, not just a CVSS number and a shrug.
Re-test included
We verify your fixes and issue a clean report - closure, not just discovery.
