Assessment
Inventory of exposed services, accounts, permissions, and update levels. Gap measured against CIS benchmarks.
Blue team — hardening
The pentest finds. We fix it.
An audit report that stays in a drawer protects no one. We apply the fixes to your infrastructure, and we verify they hold.
- Hardening according to CIS benchmarks: SSH, firewall, exposed services, permissions
- Correction of critical misconfigurations, not just reporting them
- Search for backdoors and forgotten accounts
- Post-mission support and update procedure left with the teams

Why harden
Most intrusions exploit no vulnerabilities
They occur through default configurations, forgotten services, or accounts that should not exist.
- An administration port open to the internet, a default password, an accessible database interface: these are the most common entry points, and none are software vulnerabilities.
- Overly broad permissions turn a minor compromise into a total one: a service account that can read everything gives everything to whoever steals it.
- An unpatched server will always eventually encounter a public exploit. The time between a patch release and its mass exploitation is measured in days.
- Hardening is the natural complement to auditing: one lists what's wrong, the other fixes it.
All modifications are carried out within an approved window, with the possibility of rollback at each step.

We hired White-Hat to conduct a cybersecurity audit of all our servers, and we are very satisfied with the quality of their work.

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 decide quickly — 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 we tell you before you ask
Will there be service interruption?
Rarely, and never without agreement. Changes requiring a restart are grouped into a pre-agreed window, with a rollback plan prepared.
What environments do you work on?
Linux servers, VPS, Docker containers, and the web applications running on them. For Windows Server or Active Directory, we'll specify this during scoping.
Do you need root access?
Named, temporary administrator access, revoked at the end of the mission. All actions are logged and included in the report.
And after, how long does it last?
The hardening lasts as long as the configuration doesn't drift. We provide the maintenance procedure; a six-month follow-up audit is offered, not imposed.
