Secure Source Code Review
That Finds Flaws
Before They Ship
Secure source code review
Expert Manual Review of the Code Your Business Depends On
iSpyCyber combines line-by-line manual review with static analysis, secrets detection and software composition analysis to find security flaws at their source. Every finding is validated, mapped to OWASP ASVS and delivered with code-level remediation your developers can apply immediately.
Why organisations choose iSpyCyber
Manual-first review
Experienced reviewers read the code that matters most, following data from input to sink to find flaws tools cannot.
Business-logic depth
We understand what the code is meant to do, then find where authorisation, validation and workflows can be bypassed.
Near-zero noise
SAST output is triaged by hand, so your developers only receive real, exploitable issues.
Developer-ready fixes
File and line references, vulnerable snippets and corrected code examples for every finding.
Secure handling
Code is accessed under NDA through agreed secure channels and handled within our ISO/IEC 27001 certified processes.
Continuous validation
Re-review confirms every fix, and iefyx, our AI-native VAPT and CTEM platform, keeps exposure visible between engagements.
Coverage
What We Review in Your Codebase
Our reviewers work through the OWASP ASVS requirements relevant to your application and go beyond them, tracing how data really flows through your code.
Authentication and sessions
Login, MFA, password storage, token generation, session handling and SSO integration.
Authorisation
Access control checks, object-level authorisation, role handling and multi-tenant isolation.
Injection and input handling
SQL, NoSQL, command, template and LDAP injection, plus input validation and output encoding.
Business logic
Workflow bypass, race conditions, trust boundary violations and unsafe assumptions in core functions.
Cryptography
Algorithm choice, key management, randomness, hashing and certificate validation.
Secrets in code
Hard-coded credentials, API keys, tokens and private keys in source, configuration and history.
Dependencies and SCA
Vulnerable open source libraries, outdated frameworks and licence risks across your dependency tree.
Unsafe functions and APIs
Deserialisation, file handling, SSRF, XXE, memory safety and dangerous framework features.
Languages and frameworks
Java, C#, Python, JavaScript, TypeScript, Go, PHP, Ruby, Kotlin, Swift, C and C++, among others.

Effort distribution
Where the assessment time goes
Most of every engagement is spent on hands-on manual review by experienced reviewers, not on running tools. Percentages are indicative for a typical review.
Quality built into every phase
Every finding verified
Nothing is reported until a reviewer has confirmed it in context.
Risk rated in context
Severity reflects reachability, data and exposure.
Secure code handling
Source code is protected under NDA throughout.
Closure confirmed
Re-review proves each fix actually works.
