Scoping
Repository perimeter, languages, dependencies, confidentiality constraints. Convention and read-only access.
White-Box Manual Review
Flaws That Testing From the Outside Misses
A penetration test attacks what's exposed. A code audit reads what's written — including paths no one has taken yet.
- Manual review, not a static analyzer report
- Injections, deserialization, hardcoded secrets, missing access controls
- Business logic flaws — the ones no tool finds
- Fixes proposed as code examples, ready to implement

Why read the code
A vulnerability is fixed where it's written
Testing from the outside tells you there's a problem. Reading the code tells you which one, and where.
- An injection found in black-box testing shows a symptom. The same one found in the code points to the line, the fix, and other places where the same pattern repeats.
- Missing access controls are almost invisible from the outside: you need to know the roles to understand what should be denied.
- Hardcoded secrets — API keys, service passwords, tokens — are never visible from the web and end up in the Git history.
- Business logic isn't attacked randomly: you need to have read how the cart calculates a price to know how to exploit it.
Repository access is governed by convention. No copies are kept after delivery.
Process
From repository access to fixes
Four steps, eleven days on average between scoping and reporting.
Mapping
Entry points, data flows, trust boundaries. This guides the review towards the relevant areas.
Manual Review
Targeted reading of sensitive paths: authentication, authorization, input handling, system calls, secret management.
Report and Fixes
Each finding with its location, actual impact, and a suggested fix. Re-audit included after deployment.
Example Deliverable
What does a professional audit look like?
Anonymized example: executive summary for management, consolidated score, and priorities for your IT department or integrator.
- Executive summary and risk score on one page
- Prioritized findings with concrete remediation paths
- Internally shareable document (IT Director, CISO, Management)

We hired White-Hat to conduct a cybersecurity audit of all our servers, and we are very satisfied with the quality of their work. Philippe demonstrated professionalism, responsiveness, and excellent communication skills throughout the entire process. The recommendations provided were clear, relevant, and immediately actionable to strengthen our security. We highly recommend their services.

Excellent experience with White-Hat for a comprehensive security audit of our SaaS platform. The quality of service was truly outstanding: Philippe took the time to understand our application's architecture before starting the tests, which made all the difference to the relevance of the results. The report was detailed, with vulnerabilities categorized by criticality, concrete evidence of exploitability, and recommendations directly applicable by our technical team. The post-delivery follow-up to verify the patches was a real bonus. Professional, rigorous, and attentive: exactly what you need to secure a SaaS product.

We hired White-Hat for a comprehensive audit/advanced penetration test on our website, and it's clearly the direct contact with Philippe that makes all the difference. No salesperson between us, no unnecessary jargon: we communicate directly with someone who understands our challenges and can clearly explain the vulnerabilities found. The report was precise, with concrete evidence and recommendations that we were able to implement quickly. A truly trustworthy relationship; I highly recommend them.

We urgently contacted White Hat following a suspected compromise of several servers. The team was extremely responsive and addressed our request within minutes, with clear communication at every stage. Their vulnerability analysis was conducted very rigorously, resulting in a detailed report and concrete, easy-to-implement recommendations to strengthen our security. The investigation of the compromised servers allowed them to quickly identify the source of the attack and contain the incident without any major disruption to our services. Professional, knowledgeable, and readily available, I highly recommend this provider for any cybersecurity intervention, especially in emergency situations.
The Human Behind the Tool
About Your Contact
I am a cybersecurity consultant: I support IT teams and management on audit, penetration testing, and hardening topics. My background is field-oriented (SMEs, mid-sized companies, e-commerce, industry) with a simple requirement: actionable findings, not jargon.
Why this profession: making real risks visible to help make quick decisions — securing also means clarifying what matters for the business.
Expertise built since 2020 in various contexts; recognized certifications (OSCP, CISSP, OSEP) and continuous threat monitoring.
Pedagogy: translating technical details into business decisions (prioritization, budget, planning).
Frequently Asked Questions
What you'll be told before you ask
Do you keep a copy of our code?
No. Access is read-only on your repository, and all working copies are destroyed after delivery. This is stated in the convention.
What languages do you handle?
PHP, JavaScript/TypeScript, Python, Java, Go, and C#. For a language outside this list, we'll inform you during scoping rather than pretending.
Isn't that what our static analyzer already does?
An analyzer finds known patterns and produces many false positives. It doesn't understand your business logic. Manual review is precisely for that — and we don't charge you for re-reading a tool's report.
Do we need to stop development during the audit?
No. We work on a frozen reference (branch or tag) and your teams continue. Fixes are then applied to the current branch.
