What is Secure Code Review?
Secure code review is a source-level security assessment in which experienced application-security engineers read your codebase to find vulnerabilities - insecure input handling, broken authorization, hardcoded secrets, weak crypto, and vulnerable dependencies - that black-box testing cannot reach. CyberXplore combines tuned static analysis (SAST) with senior-led manual review of authentication, access-control, and data-flow logic, tracing tainted input from source to sink. We map every finding to OWASP and CWE, and deliver developer-ready fixes that integrate directly into your SDLC.

Why it matters
Many critical flaws - broken authorization, insecure deserialization, race conditions, and logic bugs - live in code paths that runtime testing never exercises, so they survive a clean pentest and reach production.
Automated SAST tools drown teams in false positives while missing context-dependent issues; only an engineer who understands your application's intent can confirm exploitability and find chained weaknesses.
Hardcoded API keys, passwords, and tokens committed to source or baked into builds are a leading cause of breaches - and they are invisible from the outside but trivial to find in the code.
Catching a vulnerability at the code-review stage is dramatically cheaper than patching it post-release, and it builds secure-coding habits that reduce defects across every future sprint.

Our methodology
01
Scoping & Threat Modeling
We agree on repositories, branches, languages, and frameworks in scope, then identify your trust boundaries, sensitive data flows, and the high-risk components that warrant the deepest manual attention.
02
Automated SAST Baseline
We run and tune static-analysis tooling tailored to your stack to surface a first pass of injection, taint, and configuration issues - then triage out the noise so engineers focus only on real signal.
03
Manual Source Audit
Our reviewers read the code by hand, tracing untrusted input from source to sink and inspecting authentication, authorization, session, and cryptography logic for flaws that scanners cannot reason about.
04
Secrets & Dependency Analysis
We scan history and build artifacts for hardcoded credentials, tokens, and keys, and audit third-party libraries for known-vulnerable and outdated components across your software composition.
05
Validation & Reporting
We confirm exploitability, rate each issue by severity, and deliver a report with precise file and line references, secure-coding remediation, and patch examples developers can act on immediately.
06
Remediation Support & Re-Review
We work with your engineers through the fixes and re-review every change to confirm the vulnerability is closed without introducing regressions - included free.

Frequently asked questions
A pentest attacks the running application from the outside and finds what is exploitable at runtime, while a secure code review reads the source itself and finds flaws in logic, secrets, and code paths that may never be reachable from the surface. They are complementary - together they give far broader coverage than either alone.
