Hand us your code. We'll find what's hiding in it.
White-box security review by people who read code for a living. You give us the source; we trace every path an attacker could take, surface the vulnerabilities and logic bugs black-box testing never reaches — and hand you the exact fix. Always under NDA.
What we review
Any language, any stack. Read-only access to your repository is all we need to begin.
Application & backend code
Java, Python, PHP, Node/TypeScript, Go, Ruby, C/C++ and Rust — we read the language your product is written in.
APIs & microservices
Authorization logic, input handling and trust boundaries traced across every service and endpoint.
Mobile app code
iOS & Android source — insecure storage, secrets, certificate handling and unsafe backend calls.
Infrastructure as code
Terraform, Kubernetes, Docker and CI/CD pipelines — misconfigurations and over-broad permissions in the config you ship.
Auth & cryptography
Password storage, token and session handling, key management and correct use of crypto primitives.
Dependencies & supply chain
Known-CVE libraries, risky transitive dependencies and the integrity of what you pull into the build.
What reading the code reveals
Tracing untrusted input to dangerous sinks surfaces the bugs a scanner — or an outside attacker — would miss.
Injection flaws
SQL, command, template and LDAP injection traced from input through to the vulnerable query or sink.
Unsafe deserialization & RCE
Dangerous sinks (eval, deserialize, dynamic exec) reachable from attacker-controlled data.
Broken access control / IDOR
Missing or inconsistent authorization checks at the function and object level, found in the logic itself.
Hardcoded secrets & keys
API keys, credentials, tokens and private keys committed into source or config.
Weak & misused cryptography
Broken algorithms, static IVs, ECB mode, weak randomness and home-grown crypto.
Authentication & session flaws
Unsafe password storage, broken token validation and flawed session lifecycle.
Business-logic bugs
Race conditions, workflow bypass and trust assumptions only visible by reading the code's intent.
Vulnerable dependencies
Known-CVE and end-of-life libraries, plus risky transitive packages pulled into the build.
Leakage & misconfiguration
Secrets in logs, verbose errors, debug endpoints and insecure defaults left in the code.
From repo access to a fix that holds
A structured white-box review — manual depth guided by tooling, mapped to OWASP ASVS.
Scope & access
We sign an NDA, take read-only access to your repo, and agree the languages, components and threat model.
Threat modelling
We map trust boundaries, entry points and where your sensitive data flows — so the review targets what matters.
Manual review + SAST
A line-by-line audit guided by static analysis, tracing untrusted input all the way to dangerous sinks.
Proof & impact
Where it's safe to, we prove a finding is genuinely exploitable — not just flagged in theory.
Code-level fixes
Every finding ships with the exact patch or diff for your stack — the change that closes it, ready for your devs.
Free re-review
Once you've applied the fixes, we re-review to confirm they hold and nothing new slipped in.
Fixes as code — not generic advice.
A report that says "sanitise your inputs" helps no one. For every finding we deliver the root cause, the exact line it lives on, the impact, and the patch — written for your language and framework. Then we re-review your fix, free, to confirm it actually closed the hole.
Let us read your code.
Send us a note about your codebase — language, size and what worries you — and we'll scope a review and get started under NDA.
